A Thought For the New Year
More and more as we move along from day to day we realize that it is a blessing
to all of us that time is divided into two periods, and especially that it is divided
into years. Mentally, at least, on New Years Day we can close the book of the old
year with its mistakes and troubles and open up a new book for the new year.
The traditional end-of-the-year wish for a prosperous New Year is a fitting one
for any industry, business or individual. But as we have learned from past experi-
ence, more than good wishes are required to make prosperity. This is especially
true in the telephone business where a prosperous 1972 is hoped for, despite the
problems and challenges that are facing the industry as it begins the new year.
We will admit the telephone industry has growth rates it can be proud of. Ac-
cording to the TEirM Market Research Department, U.S. telephones in service
have increased from 63.9 million in 1957 to 125.7 million at the end of 1971 for a
gain of 88.6 percent. During the same period, the telephone industrys investment
in plant has soared up from $22.5 billion to |76.3 billion, for a 206 percent increase,
and gross operating revenues have gone from $7.2 billion to $22.1 billion, for a
gain of 181 percent.
In our book, thats staggering growth for an industry with regulated rates, faced
with continuing demands for new and improved services and forced to cope with
such problems as inflation, regulation and competition. However, our book and the
books the public keep are not the same, and therein lies a worrisome difference
that we believe must receive more industry attention during 1972.
It is not enough for telephone people to know that telephone companies like
other businesses have been hit and hit hard by inflation and that a fair return on
telephone company service facilities is essential to each telcos ability to meet all
service demands.
Certainly, as we have said before on this page, one of the big jobs of today and
tomorrow is to obtain the publics understanding of the need for increased rates
and improved earnings. Today, hundreds of telephone exchanges are trying to get
along on rates and earnings that are insufficient in todays inflationary economy.
In many, many places, rates for telephone service have not been increased for over
20 years, despite the fact that costs of telephone company operations are the high-
est ever known.
We know, and you know, that no telephone company can long be prosperous
and continue to effectively serve the needs of its subscribers if it continues collect-
ing for its services on the rates of bygone days, and paying its expenses on the
level of todays operating costs. But, the evidence plainly indicates that many telco
customers do not understand such facts of telephone life.
To create such understanding appears to be one of the main jobs ahead for the
telephone industry in 1972. If the job is done promptly and correctly, perhaps a
telco customer will soon realize that if he paid his telco in dollars that had the
same purchasing power as 1953 dollars, many rate adjustments would be unneces-
sary. Thats one fact telco customers fail to recognize.

The Lynch B320 D2 Channel Bank
is human-engineered to simplify your

Thats why Lynch put as much
thought into the layout and design of

and strapping options. The result is
simplified installation and less labor re-

Up front, maintenance has been sig-
nificantly reduced by elimination of field
adjustments in the common equipment.
Channel units are equipped with a busy
indicating lamp and individual make-
busy switch. Line up and testing of the
system is simplified by using a digital
signal generator located in the auxiliary
shelf. The B320 has its own carrier

Gold in Central Florida
Building a city takes forever.
Look at New York. It still isnt
finished. Paris is still being built
200 years after its plans were
laid. Athens is still shaping up
after 2000 years.
The words arent particularly pro-
found but coming from a chap named
Steve Roth, they probably sound like
deathless prose to Florida Telephone
Corporation and General Telephone
of Florida.
As if both utilities dont already
have their hands full with growtli
problems (FTC has Disney World),
Roth is the director of planning for
GAC Properties, Inc., developer of a
new city called Poinciana on a 47,-
000-acre tract and projected for 250,-
000 residents within 10 years.
According to Max Wettstein, presi-
dent of Florida Tel, all of the initial
construction and next few years will
be in FTC territory (screened area in
map).
Its been several years now since a
close observer of the scene was calling
his friends to advise them to buy Flor-
ida Tel stock not as you might think,
for the long-pull, but because they
were a likely target for merger. None
of that has happened and with the
way Florida Tel stock is held, it fig-
ures to be politically almost impos-
sible for anyone who might even be
in a position to take on the giant-sized
capital requirements this company
faces to wrest or negotiate control.
So that leaves Poinciana right
squarely in the hands of Wettstein,

shy about saying they expect to play
an important role in establishing a
new modern telephone system for a
substantial part of this great new de-
velopment.
Independents Must Adapt
Some years ago, began Joe Gallo-
way, when I was a freshman at col-
lege, we were shuffling around in the
auditorium, confused in finding our
proper seating. Finally the Dean
rapped on the rostrum and said: Gen-
tlemen, the test of intefiigence is
adaptability to a new environment.
We found our seats quickly. I think
we in the Independent telephone in-
dustry are also having our intelligence
tested in a new environment.
The chairman of Winter Park Tele-
phone Company and second vice pres-
ident of the USITA then went on to
the heart of his speech at the recent
Florida Telephone Association con-
vention, which was reported in
TEh-Ms December 15 issue. The
points made regarding yet-to-be-re-
solved FCC and other regulatory de-
cisions affecting the telephone indus-
try were among the most perceptive
we heard in 1971 and if you missed

Who Wants Dial Phones?

Nevada who are complaining about

phones are an integral part of history
of the Bell System as well as of the
Comstock Lode. It seems outrage-
ous that a company that helped
create communications history in Ne-
vada would destroy what is so obvi-
ously an asset to them, says Pub-
lisher Johnny Gunn.
One has to wonder, however, how
much of the thunder was drummed
up after the customers learned that
contrary to what some believed, the
dial phones would not bring lower
rates. (But neither will the rates go
up.)

EEOC Filing Charges Bell System Discrimination
What must have been the most prodi-
gious initial case in regulatory hearing
was carried, in large boxes, to the
FCC, when the Equal Employment
Opportunity Commission unveiled the
details of its charges that AT&T and
Bell System companies have engaged
in widespread employment discrimi-
nation.
EEOC distributed to parties to the
FCC hearing case a presentation
amounting to about 2500 pages, and
backed it up by making available to
serious students some 20,000 pages of
material obtained from interrogatories
to the Bell System companies and its
own files.
Hearings before FCC Examiner
Frederick W. Denniston are due to
begin January 31, and presumably
will be devoted for a while to argu-
ments about the admissibility of por-
tions of the seven main exhibits of-
fered by EEOC. The FCC probably is
on its way to one of its longer and
more complex proceedings, if for no
other reason than the fact that EEOC
distributed direct testimony of 17 wit-
nesses, totaling some 500 pages. There
are, in addition, a number of other
parties to the case, and testimony of
other witnesses is to come later in ses-
sions on the West Coast.
Lost in the welter of pre-hearing
publicity, after EEOC distributed a
300-plus page summary of its case
to the press, was the fact that the
FCC Common Carrier Bureau staff
also offered extensive direct testimony
by two witnessesprominent econo-
mist Robert R. Nathan, and Dr. Bar-
bara R. Bergmann, who heads the
University of Marylands project on
the economics of discrimination.
The newspaper stories were based
on the EEOC snmmary, prepared by
EEOC Attorneys David Copus and
Lawrence Gartner, which Denniston
described as a brief in advance. Al-
though it was offered as an exhibit,
Denniston agreed with AT&T General
Attorney George E. Ashley that a
counsel exhibit could not be consid-
ered as evidence.
The statement charged the Bell Sys-
tem with being without doubt the
largest oppressor of women workers
in the United States. Although there
were substantial sections in the sum-
mary regarding employment of blacks
and Spanish-surnamed Americans,
well over half of the volume was di-
rected at the claimed systematic
sexist treatment of the Bell Systems
524,000 women employees.
AT&T Executive Vice President
Robert D. Lilley replied that the
facts suggest that the telephone com-
panies are a good place of employ-
ment for women as well as minority
people.
We believe the facts of the case,
as they evolve, will also show that
many of the specific kinds of allega-
tions made against us are ancient his-
tory, long since mooted by changes
weve already made. For example,
pension options are now identical for
women and men. Similarly, women
may, if they wish, seek employment or
ask to be transferred into crafts which
have heretofore been considered male
Many (of the EEOCs)
allegations . . . are ancient
history, long mooted by
changes: AT&Ts Lilley
jobs. Also, wage zone differentials
which the EEOC has considered dis-
criminatory have now largely been
eliminated through new collective bar-
gaining agreements.
Lilley declared that Already, we
have 7500 minority people in manage-
ment jobs. Not enoughbut we are
making good headway. That is more
than double the number of three years
ago.
We now have 524,000 women on
the payroll. Thats about 55 per cent
of our total employees. Presently,
about one in three of our management
jobs is held by women57,000 in all.
And last year alone, more than 8000
womena record numberearned
promotions into and within manage-
ment in the telephone companies.
Most of these are in lower levels of
management; we need more in higher
levels and plan to have them. This is
not a dismal picture.
Nathan, who noted that his organi-
zation has done work on several oc-
casions for both Bell System compan-
ies and the Communications Workers
of America, and thus has more than
a passing familiarity with the tele-
phone industry, reviewed in depth the
AAPs (affirmative action plans) of
Bell System companies intended to
combat employment discrimination.
He said the documents show a
substantial lack of uniformity, but
are alike in only one general and im-
portant sense: each expresses a strong
intent to provide equal opportunity to
all employees and applicants regard-
less of minority status or sex.
Dr. Bergmann took the position
that Research by a number of eco-
nomists has indicated that firms that
are sheltered from competition tend
to discriminate more than firms that
are subject to the full force of com-
petition ... It is incumbent on the
(FCC), in whose hands the regula-
tory power has been placed, to insure
that the fact of that regulation not be
permissive of discrimination, which is
outlawed by federal statute.
Basic to EEOCs contention was the
view that the operators job is the
least desirable major job in the Sys-
tem, largely because of the extremely
undesirable working conditions. Con-
sequently, turnover rates among op-
erators are quite high . . . The high
turnover significantly magnifies re-
cruiting and training costs.
Another section of the summary
continued, While the majority of the
employees in the Bell System are fe-
male, almost all jobs in the company
are sex-segregated . . . Male jobs in-
variably pay more, are more reward-
ing and provide greater promotional
opportunities than female jobs.
EEOC took the position that Bell Sys-
tem jobs were just about as segre-
gated in 1971 as they were in 1965,
when the Equal Employment Act was
passed by Congress.
Further, the filing said, Promotion
from female jobs to male jobs or
vice versa is severely inhibited by a
number of obstacles including the de-
liberate obfuscation of opportunities
and procedures, the maintenance of
sex-segregated lines of progression.

Unreasonable and discriminatory ma-
ternity leave provisions further re-
strict the opportunities of female em-

It went on to comment that Bell
has at long last recognized the extent
of the discrimination it practices
against women in management and
the definite urgency regarding change
in this area. But a concerted and dra-
matic effort is required. EEOC con-
cluded that women in the 30 metro-
politan areas on which its statistical
study in the case was based, because
they ate not distributed equitably
through the whole range of available
jobs, (they) lose $422,000,000 every
year. Nationwide in the Bell System,
women lose $950,000,000 annually.
Tax Credit Amendments
Senate amendments relating to com-
munications in the new tax legislation,
providing a 4 percent investment in-
centive tax credit for most public utili-
ties, have been generally accepted by
joint House-Senate conferees on the
measure.
In the section of the report on
public utility property, the con-
ferees noted that included among the
utilities authorized the 4 percent
credit, instead of the 7 percent ap-
plied to industry in general, are reg-
ulated telephone companies and do-
mestic telegraph companies. The bill
as passed by the House extended this
limitation to regulated internal tele-
graph companies and other regulated
companies providing communication
services.
(The) Senate amendment restored
international telegraph companies to
their status under prior lawthe 7
percent tax creditbut extended the
definition of pubhc utility property to
include communication property of
any taxpayer if it is of the type used
by persons engaged in providing regu-
lated telephone or microwave commu-
nication services and if the taxpayer
uses the property predominantly for
communication purposes.
It was noted that, in connection
with treatment of the investment
credit for ratemaking purposes, the
Senate adopted the basic structure of
the House provision with several
changes. The basic structure, it was
explained, provided three elective op-
tions, the third of which applies only
to companies which already have
been flowing through accelerated de-
preciation tax benefits.
JANUARY 1, 1972
All regulated companies, it was
pointed out, must choose between op-
tions (1) and (2) within 90 days after
enactment of the bill. They are (1)
the credit may not be flowed through
to income but may be used to reduce
the rate baseprovided that this rate
base reduction is restored not less rap-
idly than ratably over the useful fife
of the property; (2) the credit may be
flowed through to incomebut not
more rapidly than ratably over the
useful fife of the propertyand there
must not be any adjustment to reduce
the rate base.
Nixon Nominates Wiley to FCC
To no ones surprise, Richard E. Wi-
ley, general counsel of the FCC, was
nominated by President Nixon to be
a member of the FCC. Wiley was
named to the term vacated by Robert
Wells, who resigned, for seven years
beginning July 1, 1970.
It had been reported earlier that
Wileys nomination would be sent to
the Senate before the adjomnment of
this session of Congress although
there is no expectation of immediate
action. As it now stands Wiley will
be given a recess appointment after
adjournment, and the move permits
him to be paid during the interim.
His nomination then is to be sent to
the Senate within 40 days after Con-
gress reconvenes in January. Presum-
ably, this will allow time to select a
black Democrat to succeed Commis-
sioner Robert T. Bartley, whose term
expires June 30. Bartley is not seeking
reappointment, and there have been
reports he will retire in the spring.
Preston Trucking Comments
The controversial proposal of the Pres-
ton (Md.) Trucking Co. to establish
a major shared motor carrier private
microwave system from the Buffalo,
N. Y., area to Philadelphia, and on to
Washington, was laid before the FCC
after a number of interested organiza-
tions filed reply comments.

initial statements in the inquiry, again
pointed up the basic positions of the
opponents and supporters of the plan,
which the opponents helieve should
be considered a common carrier oper-
ation.
Representing another group of eli-
gible shared private microwave users,
the Central Committee on Communi-
cation Facilities of the American Pe-
troleum Institute again leveled some
of the heaviest fire against the Preston
proposal. Recalling the Preston com-
ment that, with the demise of shared
telpak, the motor carrier industry will
provide the potential market for
Preston-type systems, API asked
what of the multitude of other bulk
users who may be unable to share tel-
pak facilities in the future?
It said it can find no reason to ex-
pect that these communications users,
among others, will not also present an
attractive potential market for third
party entrepreneur arrangements. We
must therefore reiterate our view that
the potential for growth in third par-
ty entrepreneur arrangements is so
great that the authorization of such
arrangements on an across-the-board
basis would create a very unhealthy
situationboth in terms of private
spectrum availability and the econom-
ic viability of communications com-
mon carriers.
Taking issue with Prestons com-
ments that the profit issue is not in-
volved, AT&T declared that On the
contrary, there is a profit being made
on communications services under a
schedule of charges related to use
which the customer is free to take or
refuse on relatively short notice (cus-
tomer private line services). While
Preston and TMC characterize this as
a lease of facilities, it is an extraor-
dinary lease where the lease is trim-
able at will and the rent is not related
to the facilities furnished, but only
the use made of them.
The initial Preston comments, the
U.S. Independent Telephone Associa-
tion observed, bring into sharp focus
the single issue now before the Com-
mission. Preston . . . concedes that its
primary interest and concern is mini-
mizing its expenditures for private
line communications service. TMC
. . . would undertake to finance and
furnish private line service to Preston
and others, in the expectation of real-
izing a profit.
The sole issue, then, is whether an
independent entrepreneur may pro-
vide leased private line communica-
tions services to users without being
subject to common regulation by the
Commission.
Answering/Recording Standards
Representatives of common carriers
and manufacturers of telephone an-
swering and recording devices agreed
have to consider possible participation
in an effort to generate technical stan-
dards for those devices similar to the
ones being developed for private
branch exchange switchboards.
At a nearly all-day meeting at the
FCC, they agreed to provide written
views on whether they would be will-
ing to engage in such a program; bow
it would relate to the current PBX in-
dustry advisory committee to the
FCC; and what kind of mechanism
should be set up for any such endeav-
or.
ALL YOU NEED
TO KNOW ABOUT
PHASE JITTER
The HLl family of SIX Phase Jitter Meters offers you a wide
range of instruments to meet your measurement requirements.
All are simple to operate, have complete level metering, and
five have a built in phase stable transmit test tone source.
And, there is no need to pay for operating modes which con-
fuse channel noise, spurious signals and T carrier quantizing
noise with phase jitter.
Take the Model 56for example. This compact unit is designed
to Bell System specifications and measures peak-to-peak phase
jitter on 3 and 30 full scale ranges. It accepts conventional
and T carrier test frequencies and operates with input levels
of -40 to +10 dBm. It has provisions for line hold and dial
thru and has a CAUTION light to warn of incorrect input
levels or frequencies. It can also be used in making noise free
frequency offset measurements and has a built in level meter.
Now where else can you buy a unit with all those features for
$965.00 in unit quantities?
Our free Applications Note No. 4 presents a factual discussion
of the relationship of channel noise and T carrier quantizing
noise to the measurement of phase jitter. Write for it, you
will find it timely and informative.

Management Notes
by Don Wiley
Thats a Lot of Money
Theres no two ways about it, $166
million is a lot to ask for in a rate in-
crease, and, naturally, since Ohio Bell
asked for that much last August, it has
found itself the target of such custo-
mer remarks as Its an attempt to
gouge the public.
As nearly all companies do, Ohio
Bell substantiates its case with
well-reasoned testimony and docu-
mented exhibits. But heres where
many companys fall down on the job;
they forget to fully inform their best
goodwill ambassadorsthe em-
ployees. Every employee at one time
or another finds himself in a position
to explode misconceptions and mis-
understandings that friends, neighbors
and relatives have about why the tele-
phone company needsor doesnt
needanother rate increase.
In a special 32-page edition of the
companys employee magazine, per-
spective, Ohio Bell has done a tremen-
dous job of compiling facts about the
rate increase application so that all
employees taking time to read it will
be in a better position to support the
companys request. Rather than sim-
ply state the facts alone, the company
conducted a poll of 850 employees
selected at random throughout the
state, asking them about their feelings
on service in general, the rate struc-
ture, the profit record and other issues
that might come up in a rate case.
This information was then used as a
basis for the presentation.
The issue includes: an interview
with Charles K. Esler, vice president,
rates and revenues; how much local
rates will be increased; why there
isnt one local service rate for all ex-
changes; how EAS will be affected;
foreign exchange rates; the reasons
for higher service connection and non-
published number charges; an ex-
planation of the tax adjustment clause;
commissions on pay phones; long dis-
tance rates; legal steps in a rate case;
and, for those with a need to know
more, a tear-out form for specific
questions. One last touch is a small,
pull-out card that can be used as a
handy, quick reference on present and
proposed local rates.
In short, the issue is a well-thought-
out presentation that gives every
company employee the proper an-
swers they need to present the com-
panys rate case where it countswith
the bill-paying public.
Black ESS Project Completed
Despite opposition by some unions
and the refusal of contractors to bid
on the job, which had to be awarded
on a cost-plus basis, construction has
been completed on a $3.5 million ESS
office for New Jersey Bell at Newark.
The problem had centered around the
work force, which consisted of 70 per-
cent black workmen.
Company Building Engineer Rob-
ert Gardner said, We were told wed
never get enough skilled black work-
ers in this city to do the job and wed
have to train them brick by brick and
board by board, but the project
worked out very well.
The concept for such a project
came from Robert D. Lilley, then
New Jersey Bell president, and now
AT&T executive vice president. Lilley
had been head of the Governors Com-
mission on Civil Disorders, which, in
investigating the 1967 Newark riots,
concluded that a lack of job opportun-
ities for the citys predominantly black
population was a prime cause of the
riots.
Lilley formally proposed the pro-
ject in a 1969 letter to the Master
Builders Association, but met with
negative reactions and feelings that
the project would be doomed by
union opposition. It finally took a
black general superintendent of one
contracting firm and a government in-
vestigation of charges of budding
trade union discrimination on another
project to get the program started.
Now, despite union foot-dragging
and attempts to stage a walk-off, the
building was completed on time and
in line with original cost estimates.
Off-the-Job Accidents Rising
With the ratio of off-the-job deaths to
on-the-job deaths at almost three-to-
one and the number of off-the-job in-
juries reaching 3.2 mdlion annually,
company safety supervisors have
found that creating campaigns to pre-
vent accidents away from work as a
great a challenge as building a good
on-the-job saftey program.
A 30-page booklet called Ideas in
ActionPromoting Off-the-job Safety
is available from the National Safety
Council to show what other businesses
have done in dealing with the prob-
lem in an attempt to spark the imagin-
ation and trigger new ideas. Intended
as an idea book rather than a source
for complete, ready-to-use safety pro-
grams, the booklet conveniently
groups the activities described accord-
ing to their suitability for company-
wide, traffic safety, home safety and
public safety programs.
Copies of the Ideas in Action book-
let, stock number 194.01, are avail-
able from the National Safety Council,
Dept. TEM, 425 N. Michigan Ave.,
Chicago, 111. 60611. Prices are 88
cents per single copy; 58 cents each
for between 10 and 99 copies; and 50
cents for 100 or more.
Continental Award Program
A Merit Award of Service to honor
employees whose actions directly re-
sult in saving the life of another in-
dividual has been established by
Continental Telephone Corp.
The award plaque reads: In recog-
nition of outstanding service to his
fellow man . . . No award can be
enough for saving a life . . . Yet no
reward could be greater than accom-
plishment of the deed alone.
In addition to the personally in-
scribed plaque, the merit award in-
cludes a $100 U.S. Savings Bond.
Management Trainers Guide
A free, 15-page trainers guide, enti-
tled Modular Management Program
No. I, explores the principles of man-
agerial roles and goals by breaking
down the topic into four specific are-
as: performance appraisal, delegation,
decision-making and group problem

[TE<b-M, 7/15] in order to consider
lawful alternatives to the method used
by the commission in calculating in-
come tax expense.
The action was taken following a
state Supreme Court ruling that an-
nulled a 1970 interim decision by the
PUC permitting Pacific Telephone to
use accelerated depreciation with the
normalization method of accounting.
The court ruled that the PUC had not
considered other alternatives to the

General contends that a customer
opinion survey could not measure the
quality of service as well as other
methods, and although the commis-

Indiana Bell has filed for a $12,-
800,000 increase in intrastate long dis-

monthly service. Overall, the request
is for about a 5 percent increase in
revenues.
In Vermont, the Public Board has
approved a stipulation by New En-
gland Telephone Co., public counsel,
the state and the commission staff,
calling for a $1,900,000 rate increase,
principally from such optional ser-
vices and intrastate toU calls.
The Mississippi Public Service
Commission, acting on a South Cen-
tral Bell application for an additional
$20,100,000, has authorized a $12,-
900.000 rate boost.
With hearings still in progress on
Michigan Bells request for a $59,-
700.000 rate increase, the state Public
Service Commission has granted the
company an $18 million interim in-
crease, an increase of about 3.25 per-
cent in intrastate revenues.
AT&T has filed tariff changes with

specialized common carrier proceed-
ing represents an abrupt reversal of
long-standing FCC interpretation of
the regulatory requirements of the

In addition to making the argument

New York Tel Furnishing
Couplers for Areata PABX
In a solution to an immediate prob-
lem that is not to be construed as a
precedent. New York Telephone Co.
agreed to furnish CDS-type couplers
to link a PBX switchboard furnished
by Areata Communications, Inc., to a
new office location of Chemtex, Inc.,
in Manhattan.
The agreement, after New York Tel
earlier had pointed out that its priority
system during the plant employees
strike prevented such new installa-
tions, eliminated the immediate possi-
bihty of FCC action. Earlier, it had
been suggested, in the wake of a
deadline for discontinuance of Chem-
tex telephone service because Areata
had hard-wired the PABX to New
York Tel trunks, that the FCC Com-
mon Carrier Bureau might ask all con-
cerned to maintain the status quo un-
til some solution for such controver-
sies during the work stoppage could
be found.
RCA Satellite Application
Amended to Double Capacity
RCA Global Communications, Inc.,
and RCA Alaska Communications,
Inc., have filed an amended applica-
tion with the FCC, calling for the
doubling of the domestic communica-
tion satellite system proposed in early
1971.
The new filing proposes that the
number of transponders in the sys-
tems satellites be increased from 12 to
24, and, as the result of an agreement
with NASA, that augmented Thor-
Delta rockets be used to launch the
spacecraft.
It was noted that the increased sys-
tem capacity is designed to meet peak
television requirements on weekends
and to serve the communications
needs of common carriers and private
industry. Each transponder could han-
dle a TV channel or 1000 voice chan-
nels or a 34-megabit data stream.
Unusual Business User Class
Not Required Says PUC Staff
There is no adequate factual basis at
this time to warrant setting up a spe-
cial class of unusual users of busi-
ness telephone service, or to justify
the filing of such a tarifiF, the Califor-
nia Public Utilities Commission has
been told by a special committee of
its staff and other interested parties.
The committee had been estab-
lished as part of the general Pacific
Telephone Co. rate proceeding, in a
commission investigation into the
ramifications of data exchange service,
principally telephone service to time-
sharing computer companies. The
PUC may study voice and non-voice
business usage which substantially dif-
fers from average business usage,
either in terms of holding time or vol-
ume of messages. Consequently, the
committee was set up to identify and
consider the service and rate aspects
of unusual business use.
The report, based on a Pacific Tel
study, indicated that time-sharing
computer companies have a higher
use per line than the average business
customer. It did not show whether
there are other classes of users that
also substantially deviate from the
average. Reporting the committees
findings, PUC Attorney Richard Gra-
velle said it was concluded that there
is no emergency regarding unusual
telephone use in California.

STANDARD
TELEPHONES
PROGRAM FOR
SURVIVAL
Short on capital sources but long on
good management and morale, this
optimistic Georgia Independent is
out looking for new ways to serve its
customersprofitably!
Responsible for management of Standard Telephone Company
are (I. to r.) Dean Swanson, executive vice president, H. Milton
Stewart, Sr., chairman of the board and chief executive officer,
and H. Milton Stewart, Jr., president.
Survival? Theres an Independent telephone
company in the Appalachian foothills of
northeast Georgia which is acting like it never
heard that small telcos are supposed to be wor-
ried about their continued existence.
The Standard Telephone Company of Cor-
nelia, Georgia is too busy meeting the POTS
needs of its customers and implementing ways to
offer other telecommunications services (for a re-
turn on its investment, to be sure) to even doubt
seriously that it will be around just as long as it
chooses. And thats a long time, baby.
Telephone Engineer 6- Management recently
traveled the territory of this 20,200-station REA
commercial borrower, probing the operations
and management thinking. TEirM found that
there was no particular magic in the things Stan-
dard was doingsimply a confident, intelligent
approach to its job, a genuine sense of mission
by well-paid employees and a desire to capitalize
on growth potential through innovation. Com-
munity support was very evident.
And if there is a renewed bounce in the step of
H. Milton Stewart, Sr., 74, chairman and chief ex-
ecutive officer, it is because he can see that op-
erations are being managed capably by President
H. Milton Stewart, Jr., 33, and Executive Vice
President Dean Swanson, 39, his son-in-law. And
this comes at a time when many closely-held
family telcos are being pressured into mergers.
Lets take a closer look at this companyits
physical characteristics, management philosophy,
performance, problems and how it views its fu-
ture.
Covering a 1500 square mile territory about an
hours drive from Atlanta, an inflow of both per-
manent residents and vacationers has led to a
doubling of station count every six years in the
past 20 years. Thirteen exchanges have climbed

We feel the telco canand shouldfree itself from
providing non-essential communications services on immediate demand.
Continued
from 6369 telephones in January 1961 to 20,209
in October 1971. During this decade, company-
owned toll channel miles increased from 8 to
5100, EAS circuits from 3259 to 21,944 and gross
plant investment climbed from $1,800,000 to $10,-
800,000. At the same time, unserved applications
dropped from 1100 to 35. Observers recognize
that these statistics exceed national averages.
(See box for other company figures.)
In reviewing the financial history of the com-
pany and looking ahead, Stewart, Sr. had this to
say: Until 1945, we survived literally by stretch-
ing every dollar and each mile of plant, and es-
pecially through the faith of local bankers. In
1944 a crisis was averted when our banker ar-
ranged for a RFC loan. From 1945 to 1954 both
the RFC and Stromberg-Carlson supplied credit
for plant improvements and we used internally-
generated funds to pick up deteriorating adjoin-
ing properties. We spotted further growth com-
ing in 1954 and received our first REA loan for
$900,000 and were just notified by Herman Tal-
madge on December 9 that our H loan for
$850,000 was approved. We needed it badly.
Theres no doubt that huge (for us) new capi-
tal outlays will be necessary to serve about 15,000
new subscribers over the next 10 years. Including
extensions, we look for at least 40,000 stations by
1980. Frankly, with any immediate REA loans
not adequate to do all that wed like to do, and
the infant Rural Telephone Bank under tremen-
dous pressure, were reviewing our internally
generated funds to improve this source of financ-
ing.!
As a step in this direction. Standard Tel in
early 1971 submitted a depreciation rate review
to the Georgia Public Service Commission. The
study utilized a mortality dispersion factor (Iowa
Family of Curves) to show that an increased de-
preciation rate was justified. No decision has
been handed down. Recently, the company sent
its director of settlements, Conley Cathey, to the
first USITA Cost Separations School. In 1972 a
full cost separation study will be conducted to

determine if going cost will provide an increase
in settlements over the present average sched-
ules.
Its cautious optimism notwithstanding, long-
term financing has to be one of Standards nag-
ging concerns.
And what has the company been doing with
these dollars?
In 1964, Standard committed itself to full area
coverage with one and two party service in the
base rate areas and four party flat rate rural ser-
vice. The program was completed in 1969.
Among the highlights during this period, the
company acquired or built all of its present toll
routes, constructed a Farinon microwave station
atop Brasstown Baldthe highest mountain in
Georgiato deliver three phone circuits to the
U.S. Forestry Service and tourist center, and got
into the CATV business on a lease-back basis.
Forecasting Station Growth
Forecasting, admits Milt Jr., is still less than
perfect science.^ Weve found that for overall
growth, straight line projections have been ac-
curate. Its not so much the total, but where, that
gives us trouble. We expect that household
growth is going to accelerate and that as afflu-
ence increases and available grades of service
improve, were going to get more rural applica-
tions. Using 1970 census figures, a residence
growth study indicates telephone saturation from
1960 to 1970 increased from 35 percent to 67 per-
cent. Adding 7552 residence main stations re-
duced the number of unserved households by
1427, reflecting that the number of new house-
holds increased by 6125 in the decade. Within
two miles of base rate, 90 percent of establish-
ments have service and beyond two miles, 50 per-
cent have service. The upswing in rural service,
plus rising costs in general, will accelerate the in-
vestment per station.
Standard is quick to foresee that its achieve-
ments of the 60s will be dwarfed by the com-
plexities of the 70s. Its strategy, as the younger
Stewart and Swanson tell it, stresses flexibility:
Like the rest of the telephone industry, our situ-
ation is compounded by an unstable economy,
consumerism, federal regulatory uncertainty,
new service demands and accelerating equip-
^Standard has on application a $2.5 million REA loan to help
finance its anticipated $1 million construction budget in 1972 and
beyond. Like many others, it looks for Telephone Bank appropria-
tion.
-One method Standard plans to use in 1972 to better pinpoint
both where its development is now, and to plot future cable
facilities, is to take periodic aerial photographs along major ca-
ble routes. Ex-Navy pilot Swanson flies the territory regularly in
his sniall plane.
'^As of October 1971 the embedded investment per main station
was $732 and if including extensions, $540. By comparison, the
average costs figured for just the ijears 1966-70 were $1050 and
$672 respectively.

ment obsolescence. Then along comes Carterfone
plus the renewed realizationwe saw what hap-
pened to Penn Centralthat utilities are not nec-
essarily a safe investment.
Sure, were e.xcited about the opportunities for
increasing revenues from new communications
service. But lets face it, the squeeze for addi-
tional capital plus qualified personnel is also
more acute. We feel that a real danger from the
opportunities comes when a telephone company
spreads its resources so thin through meeting
new service challenges that deficiencies arise in
its basic objective; that is, the ability to provide
and maintain top quality basic telephone service.
To stretch the point, assume that all of the
resources of a telephone company may be neces-
sary to provide the very best Quality of Plain Old
Telephone Service and that the use of the com-
panys resources to provide non-essential services
may not he in the overall public interest, no mat-
ter how much these services are in demand by
small segments of the public. Perhaps it is this
logic that has shaped many recent regulatory de-
cisions, especially after viewing the many service
failures of some of the nations largest utilities.
We feel the telephone company can, and
should, take the initiative of (1) freeing itself
from the obligation of providing various non-es-
sential communication services on immediate de-
mand and (2) receiving revenue to be derived
from marketing these services through competi-
tive enterprise. These two objectives need not be
contradictive.
At this point, management shifts from theory
to action.
Forming Communications Subsidiary
Standard Telephone is in the process of form-
ing a subsidiary corporation to the parent com-
pany, which may compete directly in some areas.
The Stewarts point to a number of reasons for
their decision, in addition to relieving the telco
from the obligation of providing other than basic
communication service as a matter of public
convenience and necessity:
1. It will open up a new source of capital free
of the first mortgage position held by REA. (e.g.
Leverage is increased and additional debt capi-
tal may be obtained from public and private
sources.)
2. It will have the dual effect of meeting inter-
connect competition through (a) the parent
Telephone Companys regular lease-service
agreements and (b) the subsidiary companys
sales/lease-service arrangements in the com-
petitive market.
3. Stock of the subsidiary can be sold to the
public without affecting the membership control
of the parent telephone companv. This has a
further benefit of attracting good management
personnel through the offering of stock options
by the subsidiary.
4. Special services could be separated from

basic services in fact as well as in pricing con-
cept, requiring cost studies and accurate pricing
of special services so they could stand on their
own unsubsidized value to the general public.
5. The subsidiarys sales territory would not
necessarily be confined to the certificated area of
tlie telephone company.
6. Profits from the subsidiary, operating in the
competitive market can be maximized to the ex-
tent of free market limitations.
Standard is quick to point out that what it is
proposing is not new to the Independent indus-
try. We keep our eyes and ears open to what
other companies are doing, says Swanson, and
try to measure up to the leaders and innova-
torssuch as Rochester Telephone, Winter Park
Telephone and Chillocothe. Asked if they really
intend to compete against themselves in the
case of interconnect, Swanson put it this way:
As a telephone company we havent lost a cus-
tomer yet. Our customers know our special Busi-
ness Customer Team by name and that they can
reach us for maintenance on PBXs and keysets
anytime day or night. With the distance we are
from Atlanta this is still a major consideration.
But its certainly probable that more interconnect
competition will come out our way and we plan
to be ready. If a customer is adament about put-
ting in his own system, rather than let the busi-
ness go elsewhere, our subsidiary will sell him
the equipment and even a maintenance contract.
Were going to outhustle these fellows.
Phase 1 of the program would transfer owner-
ship of the companys CATV plant, its burglar
alarm and intercom sales and service to the sub-
sidiary. The subsidiary would also install and ser-
vice two-way radio and IMTS. Phase 2 would in-
volve new product lines, MATVs, CCTV, ETV
via coaxial cable (already being discussed in
Georgia), data communications still in slight de-
mand in Standards territory, PABXs and facsimi-
le-all envisioned with the flexibility of straight
sale, sales with maintenance contracts, lease op-
tions, or maintenance only. Even now the telco
accepts many electrical shop type functions on
a non-tariff, cost-of-labor basis. These would be
directed to the subsidiary.
Obviously, separate books and careful watch
on transfer of personnel will be in effect from the
start. While some telco employees will be in-
volved in the early stages, the subsidiary will
have some permanent staff. Sure, were ready to
make changes as necessary, affirms Stewart, Jr.,
and we may get shot down by regulation not
yet made or spelled out. But well try anything
once rather than sit on our hands. The technical
experience all of us have gained out of CATV,
for instance, outweighs the frustration we feel at
the prospect of possibly losing our hard-earned
investment.^
An Outstanding Training Record
Getting back to the telephone company. Stan-
dard works hard at doing a lot of taken-for-
granted industry practices at above-average lev-
els. For example;
1. Training. In the past two years, 86 of its II7
employees have been sent to USITA and supplier
sponsored schools and seminars throughout the
country, representing 3226 classroom hours . . .
not counting internal workshops and manage-
ment seminars. In this same period, 38 employees
have attended local colleges on their own ini-
tiative with the incentive of knowing that the
company promotes vigorously from within where
qualification exists. We are blessed, says Milt
Jr., by having the North Georgia Technical and
Vocational School just 10 miles from Cornelia.

three-year electronics technician. Standard
claims its low turnover in all types of employee
is because most people are local and want to
live in this area. We firmly believe in giving peo-
ple jobs they enjoy doing, train them well, help
them improve, and pay them above scale.
2. Public Relations. Stewart Sr. has long been
held in high esteem by Independents for his com-
mitment to good corporate relations. A past di-
rector for 12 years of the USITA and chairman of
its Public Relations Committee, his methods were
cited many times by the Telephone Advertising
Institute as models for other small telcos to fol-
low for being modest in expenditure and effec-
tive in results. The companys employee news-
paper, The Standard Bearer, is printed monthly
on a Xerox 2400 copier with a pre-printed color
letterhead and logo. It contains all the usual fea-
tures designed to keep the employees informed.
In addition, periodic luncheon meetings are held
on a departmental basis to bring the executives
into personal, informal contact with everyone.
Standard Tel points to more than lip service in
saying tliat quality of service is the cornerstone
of good external public relations. The Georgia
Public Service Commission receives less than a
half dozen letters of complaint a year from Stan-
dard subscribers, even though station growth
rate has annually been exceeding 10 percent.
After acceptable performance, muses Stewart
Sr., our PR program really boils down to civic
participation. Rather than playing up Standards
problems and activities to the public, we get in-
volved in public affairs. The result is a company
humanizing process in which much is learned
about the people and the people get to know
Standard Telephone not as a cold entity, but as a
group of citizens involved in the community.
This approach takes time to successfully develop,
but once established, the subscribers become
understanding toward our problems in much the
same way we responded toward their problems.
Milt Jr. is presently president of the Chamber
of Commerce and the Lions Club and various
others have participated in the full range of civic
groupsfrom developing a recreation park to a
county airport. Swanson, incidentally, just com-
pleted a term as president of the Georgia Tele-
phone Association, a position held by Stewart Sr.
in the 40s.
3. Industrial and Community Development.
^Multi-View TV Inc. . is a 600-suhscriher system covering 23
miles in the Cornelia area. Potential hookups are estimated at
1000 out of a total of 1400 homes and the company has just
turned profitable after being in business three years. Stock is
held privately by Stewart Jr., Swanson and the owner of the local
radio station. Unless their planned waiver is granted, the telco
officers would have to sell their interests by 1974 under FCC
riding. Multi-View would still have the option of retaining its
contract with Standard or putting up its oion cable under joint-
pole rental. But, points out Stewart, whats to stop somebody
from bidding for another CATV franchise and leasing the plant
from the telephone company?
^Standard Tel has 25 college trained employees on its payroll.
Its only full graduate engineer is Stewart, Jr. (Georgia Tech),
although Annapolis graduate Swansons BS and additional military
training is the equivalent of an engineering background.
*^The company does advertise in local newspapers and carries on a
close editorial news liason with the press.
While this also becomes a part of public rela-
tions, in Northeast Georgia it has exploded into
big business. Not only has northern textile moved
to the South and other plants pushed out from
Atlanta, but tourism is blossoming. Coming
through now is the under-construction Appala-
chia Developmental Highway (Georgia route
400) with the approved 187-mile extension of the
Blue Ridge Parkway soon to also bisect Stan-
dards territory. Expansion will follow. An exam-
ple of how the area is gearing for growing recrea-
tion development and Standards role is illus-
trated in the small town of Helen.

Capsule History of Standard Telephone
M. C. York, a Clarkesville (Ga.) businessman, and several associ-
ates founded Standard Telephone in 1904 and built exchanges in
Clarkesville and Cornelia. Meanwhile, H. M. Stewart entered the
telephone industry in 1916 as a night operator while still in high
school in his hometown of Centerville, Alabama. After several
years with Southern Bell, he joined Kellogg Switchboard and
Supply as a sales representative. In the early '30s, Stewart was
named secretary of the Texas Telephone Association and later
held the same position in Pennsylvania. He purchased the two
Georgia exchanges and their 419 telephones in 1939. Stewart
went on to work for the Gary Group in Fort Wayne as a vice
president-public relations before moving to Cornelia permanently
in the early 40s. In 1944 he bought the Dahlonega exchange
and a year later reactivated the abandoned Hiawasee exchange
and its 11 stations. The familiar pattern followed until the 13th
exchange in a six-county area was built in 1963. Standard ob-
tained its corporate charter in 1951, crossed the 5000 telephone
mark in 1958 and installed its 20,000th station in Sept. 1971.

Until a few years ago, say the Stewarts,
Helen was a faceless town with marginal
growth. Leaders decided to completely renovate
the village with a Bavarian theme in keeping
with the mountainous setting in order to attract
tonrists. On request of these town fathers, the
telephone company, at its own expense, placed
all its facilities underground and installed two
Bavarian style paystations to fit in with the over-
all theme. Visitors have reached staggering pro-
portions and the resulting trade is rapidly repay-
ing the residents, who performed the entire reno-
vation with their own private funds. Standard is
also experiencing repayment from its part, as
gross revenues from the exchange jumped 30
percent higher then the year prior to renovation.
Another of our towns, Dahlonega, which is the
scene of the nations first gold rush, has since
started a similar renovation program using a
Western theme. Again, we placed our plant
underground and assisted in other ways.
In another avenue, so-called problems can be
turned into an opportunity. In Dahlonega, chil-
dren were using the companys central office and
pole yard grounds for play area due to a lack of
playground facilities in the low income neighbor-
hood where the office is located. The children
were causing considerable damage such as glass
Standard Shares in Leased Computer
Sixteen Independent telephone companies in the states
of Georgia, Tennessee, Mississippi, Alabama and Florida
are both stockholders and customers of Teledata Corpo-
ration. The Atlanta computer center was formed in 1968
to handle the subscriber billing and toll processing
needs of Independents. With a data processing profes-

breakage, sign and light damage as well as pos-
ing a question of liability in the event of an acci-
dent. Standard responded by spending $4000 to
turn part of the pole yard into a paved basketball
court and playground. As hoped, the vandalism
dropped immediately.
Another example of being a good neighbor oc-
curred at the Cleveland office. A conference
room which can be entered from the outside of
the building is being prepared so it can be locked
off from the remainder of the office. This will
help alleviate a problem civic and church groups
in that town have in finding meeting space, since
all such groups are invited to use Standards
room free of charge. All that is required is that
the group leader make a specific reservation for
the use of the room, pick up the key from the
Cleveland District Operations Manager and re-
turn the key the following day.
4. Operations
While, again, much of what Standard does is
routine for telephone companies, it evidences a
firmness of purpose and practice based on dis-
covering what works well in its own bailiwick.
The company, for instance, opens a new business
office whenever a location reaches 1000 stations,
hires a local girl, and has a district manager who
runs the central office. Weve found that our
customers like to talk to the telephone company.
Our COs operate like little telephone companies
and, says Swanson, I wouldnt even have to go
to many of them if I didnt want to. We do give
our managers a wide latitude of purchasing and
decision making. Once a month the district man-
agers come to Cornelia for a meeting.
Standard has found that paystations are a
growing part of its revenue. Its 135 booths aver-
age about $50 a month after the A station set-
tlement. While vandalism is not serious, profes-
sional thieves who pass through the territory on
their way south every year provide a yet-to-be-
solved problem. The company is also subject to
its share of misleading yellow page directory in-
voices and plastic directory cover salesmen.
(When we know theyre in town, we rush a let-
ter out to our business customers advising them
that if we find the covers on the books of our
subscribers, we will remove them.)
Reasonable Rate Structure
Not an incidental reason for its satisfied custo-
mers is the companys rates. In its EAS groups,
typical charges are residential city 1-party $4.50,
2-party $3.75; business city 1-party $7.40, 2-party
$6.40; residential rural multi-party $4.75, busi-
ness $6.15. One and two party command an ad-
ditional mileage charge. Where there is no EAS,
residential city 1-party is $4.25, 2-party $3.50;
business city 1-party $6.40, 2-party $5.40; resi-

dential rural $4.40, business $4.65. Residential
extensions go for $1.25, business $1.75. New in-
stallation charge is $6 for business, $4.50 for res-
idence. They drop to $3 when apparatus is in
place. Standard makes no charge for white, beige
and black instruments and has a $5 tariff for all
other colors.
Naturally, Plant occupies the companys most
careful plairning. With a look toward tone dial
and other options which require sophisticated
CO apparatus, the cost of an electronic office
credited with salvaged step equipment and re-
duced floor space is being weighed against the
cost of sendeiizing present S x S equipment. This
has particular significance as the company looks
toward full area coverage with one-party service
at a flat rate. Standard hopes that this program
may be begun by 1975 with completion by 1980.
By this time, adds Plant Manager Tim Craven,
perhaps the state-of-the-art will allow maximum
usage of station carrier and concentrators to cut
costs and relieve congestion as the ground be-
comes staturated with various utility services. As
another hedge against ground congestion, the
company is studying various methods to allow
easy reinforcement of buried plant once the first
cable is placed. One of these is vertical and hori-
zontal space allocation while another is the plow-
ing of an empty duct with the initial cable.
Lightning brought about by summer storms,
is probably the companys biggest natural buga-
boo. Poor grounding conditions requires careful
outside plant planning, especially as more fine
gauge wire with carrier derived circuits are
brought into service. For example, Standard has
agonized over a toll cable placed in service in
1961 with N1 carrier initially and reinforced with
N3 carrier in 1970. A lightning surge counter was
installed on a ten mile test section of the cable for
a recent ten month period, and the total number
of surges exceeding 100 volts during the period
was 14.879. Repeaters were generally protected
from damage using a floating method in con-
junction with gas tubes which performed their
function so well that surges failing the tubes also
dropped the carrier systems momentarily causing
loss of conversations. This occurred numerous
times over the ten month period, and even
though equipment damage was light, the incon-
venience caused to the customer, plus loss of toll
revenue, was intolerable. Consequently, Stan-
dard plans to file an application with the FCC to
establish a diversity system utilizing its present
microwave tower on Brasstown Bald. A new path
will be plotted via this station to the toll center
owned by Southern Bell in Gainesville, Georgia.
Trying New Cable Techniques
Standard has more than a passing interest in
keeping up-to-date on cable technology. It has
been direct burying on a broad scale since the
early 60s with more than one-half of its present
plant underground. The rock soil condition dur-
ing installation does do scattered damage to
sheath, which in turn leads to water entry and
widespread cable damage during summer light-
ning hits. (This, however, does not deter Standard
from its goal of eliminating aerial plant by 2000,
and it has set up its annual charges accordingly.)
Havens also plans to take a close look at grease
filled cable by specifying it on an upcoming con-
tract. His wry comment when questioned on
aluminum cable was: We hope the Bell manu-
factures and uses a lot of it so that more copper
is freed up for our use. One interesting tech-
nique now being used is keyed to the future.
When Plant has to go into a buried cable to re-
pair trouble, the men encapsulate the splice and,
before closing, put a tube through the splice to
allow passage. Based on a report that AT&T is
developing a system which is designed to force a
special liquid under pressure through the cable
and purge the cable of water and then setup to
turn into jelly. Standard plans to be ready.
In fact, being ready might well be the subtitle
for this aggressive telephone company which
plans to move ahead, serving as its motto states:

White Pages Editors Improve
Usefulness of Directories
Coordinating suggestions
from both employees and
customers produces a better
bookand fewer DA calls.
The average telephone directory is Uke a li-
brary. A great number of facts are there, be-
tween its covers, just as a great number of books
are found in most libraries. But unless you can
find the specific fact or book you need easily,
both are useless.
Obviously, the present-day directory repre-
sents information which must be well organized
to realize its full value. The sheer number of list-
ings have made this necessary.
Thats only part of the problem, however. The
rise of complex business structures, the increase
in government agencies, and the development of
corporate images through advertising have con-
tributed some rather confusing data to the peo-
ple who make up the white pages directory.
Since the end of World War II, the federal gov-
ernment alone has added over 17 major agencies.
Many businesses use shortened names for effec-
tiveness in advertising and corporate identifica-
tion, names such as MONY (Mutual of New
York), C&S (Citizens and Southern Banks) or
GENESCO (General Shoe Company).
For the customer, this means difficulty in locat-
ing a number, frustration and less reliance on the
white pages directory as a source of information.
For directory assistance operators, it means addi-
tional customer calls for help. In fact, the rise in
calls to directory assistance has been greater than
the growth of telephone users and the D.A. oper-
ators are becoming overburdened. And while
they are experts in locating hard-to-find listings,
they also experience diflBculty from time to time.
Until recently, responsibility for reviewing and
improving directory listings was divided between
communications advisors, service representatives
and directory sales people. The result was lack of
coordination and, too often, superficial interest.
A directory editor concept emerged from a
System Listing Improvement Gommittee which
was formed by AT&T to define problem areas
and ways to overcome them. The first Editor
Workshop was held in New York in 1968, with
System editors representing nine companies at-
tending.
The basic objectives of the directory editor
are:
A continuing program to improve the useful-
ness and reference features of telephone direc-
tories in support of their purpose as the primary
source of telephone numbers.
Interdepartmental coordination to develop
and control listing quality.
Reducing calls to directory assistance.
To meet these objectives, directory editors
must bring a wide variety of talents to their jobs.
They first of all must have knowledge of the di-
rectory itself and of associated items such as
business and government, as well as know the op-
erations and practices of other departments in-
volved in making up the directory. The ability to
communicate is also important, for they are ba-
sically coordinators between these departments.
Directory editors must have imagination to find
new and easier ways of listing information. And
finally, they must have good judgement, the abil-
ity to weigh problems and solutions and come up
with answers.
Directory editors have many sources of input
to discover where the problem areas lie in direc-
tory listings. Gustomer complaints and stockhold-
ers letters are some. Another, and probably the
most important of all, is the directory assistance
operators. Since their jobs put them into direct
contact with the problems of directory listings,
they are eminently qualified to offer suggestions
to the problem, as well as alert the directory edi-
tor to trouble spots in the directory. Keeping
aware of the operators problems is an important
part of the directory editors job.
Listing problems in the white pages can be
boiled down to three basic categories:
1. listings that dont exist but should.
2. listings that exist but are difficult to find.
3. listings that exist but shouldnt.
An example of listings that dont exist but

should can be found in trade names familiar to
the public, normally as a result of advertising.
The Aluminum Corporation of America would
certainly be found in the directory, but its more
familiar name, ALCOA, might be left out. Gov-
ernment listings can be a problem too, for al-
though the directory lists all government agen-
cies in its area, many government functions fall
under agencies whose oflBcial titles are uninfor-
mative and misleading to the average person.
Many listings exist but are difficult to find, pri-
marily because of alphabetising rules. A compa-
ny whose name starts with Northwest and a
company whose name starts with North West
are going to appear in different places in the di-
rectory. People with names beginning with Me
and Mac have similar troublesthe names Mc-
Coy and MacCoy sound exactly alike and yet in
an average sized directory they will not appear
together. Another problem in this area comes
with cute spellingsDee-light Bakery or Pair
o Dice Lounge are almost impossible to find if
one has only heard, rather than seen, the names.
The last eategoryof names that exist but
should notis probably best exemplified by com-
panies who might list a name in the white pages
in order to occupy a favorable position in the yel-
low pages. A-Aalco Moving and Storage Co.,
for instance, is obviously titled so that it will be

the first listing under Moving and Storage in the
yellow pages. Finding it in the white pages, how-
ever, is extremely difficult. Businesses might also
confuse the customer with a name that sounded
like a well-known brand name, Kenmore Wash-
er Service, for example.
All of the problems shown above are ones that
the directory editors must solve if they are to im-
prove listing quality.
The problems are being solved with the help
of the editors, using a variety of methods that in-
clude frequently called number boxes, cross-ref-
erencing, eliminating unwanted listings, adding
others and generally putting the white pages di-
rectory in the language of the man on the
street.
Government listings, always a problem, are be-
ing improved through quick reference lists. Set
apart from the normal listings, quick reference
lists give the most commonly called local, state
and federal numbers. The listings are by pro-
gramsnot departments or agenciesand thus
you can expect to find such nonoflBcial listings as
Draft Board, Marriage License, Federal Income
Tax, Traffie Court and Welfare. These quick ref-
erence lists should go far in improving the white
pages, since last year over two million calls were
received by D.A. operators in the Bell System re-
questing government related numbers.
Cross-referencing is another way in which the
directory editors are seeking to eliminate custom-
er confusion. Cross-referencing can be particular-
ly helpful in cases where the name is known but
the spelling is not. A cross-reference under the
listing for the name Cain should indicate: See
also Caen, Cahen, Caine, Cane, Cayne, Kain,
Kaine, Kane, Kayn. A cross-reference might also
help you locate a company that has changed its
name, or is now part of another organization.
The directory editors are not the first to notice
and attempt correction of these problems. Com-
munications advisors, service representatives and
director sales people still bear the primary re-
sponsibility, but the directory editors jobs put
them into a position where they can coordinate
the directory problems of TraflBc, Commercial
and Marketing. This is particularly important
when you consider that uniformity is one of the
goals of any reference book.
Basically, there is no limit to what the direc-
tory editors can do. Change of listings, however,
should have the approval of the customer, and it
is up to the direetory editor, working through
various departments, to show the customer how
his listings might be improved.

LINE CONDITIONING
FOR
DATA TRANSMISSION
Distortion
and Its Effect
By Ralph E. Willey
Part 2 explores various
types of distortion and
their characteristics.
A s mdicated in Part 1 (December 1), there are
** fundamentally three types of distortion: at-
tenuation distortion, phase distortion and non-
linear distortion.
Attenuation distortion is more accurately
known as amplitude-frequency distortion. This is
the distortion caused by variation of transmission
attenuation or loss with frequency. The attenua-
tion of typical cable pairs used in telephone
communication is proportional within the voice
band to the square root of the frequency. Where
runs of several miles are necessary, it is generally
the practice to add lumped inductances, com-
monly called loading, at uniform intervals. This
gives a lower and a more uniform frequency loss
characteristic. However, this makes the line act
as a low-pass filter with an abrupt cutoff. The
amplitude versus frequency characteristics of
typical loaded and unloaded cable pairs are
shown in Figure 2-1.
Most carrier telephone systems derive many
voice channels by frequency-division techniques.
The bandpass filters associated with such sys-
tems result in a steep cutoff at both the high and
the low end of the voice band. Typical attenua-
tion versus frequency characteristics of carrier
systems are shown in Figure 2-2.
In switched networks, there are at the switch-
ing points repeating coils, series capacitors, and
shunt inductors used in signalling and supervi-
sion. These cause voice channels to have a low
frequency cutoff even where the connecting fa-
cility is capable of transmitting DC components.
The overall attenuation versus frequency charac-
teristic of a typical switched telephone network
has a low end cutoff starting at about 300 Hertz.
The range 3001100 Hertz is relatively flat. The
range 11002900 Hertz shows a linearly rising
loss. Above 3000 Hertz the loss increases rapidly.
The effect of non-uniform attenuation on data
communication is to distort the received spec-
trum and, in turn, the data signal waveform. For
a particular channel a reasonable amount of such
distortion can be allowed for in the design of the
overall transmission characteristic. Under certain
limitations, it is theoretically possible to construct
linear compensating networks which equalize at-
tenuation distortion over the signal band. This
will be discussed in Part 5.
Phase-Frequency Distortion
By phase-frequency distortion we mean dis-

ality of phase shift to frequency. Such distortion
constitutes the most limiting impairment to data
transmission, particularly over telephone voice
channels. The main sources of phase distortion
are loaded cables and carrier channel filters. The
effect is most severe at the band edges where
there is a steep rise in attenuation.
The unavoidable capacitive and inductive re-
actances associated with various types of com-
munications channels introduce delay, because
they require a definite time to react to different
frequencies. For instance, a capacitor does not
charge instantly; it requires a definite time, de-
pending on the capacitive reactance of the ca-
pacitor and the applied voltage. Since capacitive
reactance varies inversely with frequency, the
charging time will vary with frequency. Similar-
ly, an inductance requires a certain amount of
time to build up its inductive field, and this time

also varies with frequency.
Phase distortion may also be caused by echoes
from imperfect line terminations. This is called
echo ripple and will be discussed in a later sec-
tion.
In Figure 2-1, we showed the relation of atten-
uation for cable facilities to frequency. In reality,
we consider the propagation constant which for
these media is composed of two parts. They are
attenuation and phase constant and can be
shown to be
P = a -H/3 = V(R + jwL) (G -f j(uC)
where a is the attenuation constant in nepers and
yS is the phase constant in radians. In this expres-
sion
R = Conductor loop resistance in ohms
L = Inductance of conductors in Henries
G = Leakage conductance in mhos
C = Shunt capacitance in farads
tt) = 2 77 f f = frequency under consideration
Solving the equation for a and y8, we have
= V2 [V (R"" + (G2 -h ft,2C2) + RG - oj2LC]
Id- = 1/2[VR^T^I^^L2HG2Tw2C2) - RG + ftj2LG]
If R, L, G and C are given on a per mile basis
the attenuation constant a computed will be on
a nepers-per-mile basis. It can be transformed
into decibels by multiplying the value obtained
by 8.686.
Likewise the phase constant /3 will be in radi-
ans per mile. It can be converted into degrees by
dividing by 2 tt.
It has been shown that distortion-free trans-
mission from phase delay can be obtained in a
network only if
/3 = KW + C
where K is a constant and C is equal to 27rr.
This means that phase delay versus frequency
must be linear as shovra in Figure 2-3.
A normal telephone line does not meet this
criteria. A more general type of phase curve ex-
perienced in telephone facilities is as shown in
Figure 2-4. It will be observed that the phase
characteristics of this line do not meet the
general requirements set forth for distortion free
transmission.
Even though the curve oi Figure 2-4 is not
straight, it may be assumed to a certain degree of
approximation to be straight within certain fre-
quency limits. This is shown graphically in Fig-
ure 2-4. Therefore, we may say that the phase
versus frequency (/3 vs. co) curve is a straight line
between the frequencies Wa and cOe-
However, if we take the yS curve segment from
Figure 2-6. Waveforms in and out of 10 miles of 22H88 cable.

CO and co^ to be the J3 characteristic, we must con-
sider the J3 curve intercept to be the intercept of
the extension of this line and the zero frequency
axis. It is quite unlikely that this intercept (point
j3s on Figure 1-1) will be 0 or 27rr. Failure to
meet this requirement may be expected to cause
distortion. It has been found convenient in dis-
cussing non-ideal systems to define the envelope
delay or more simply delay as the slope of the
phase-frequency curve and to speak of the de-
parture of the envelope delay from a constant
value as delay distortion.
As can be seen from the above, if yS and co do
not change in direct proposition, the phase delay
will change with frequency. Therefore, a com-
plex wave form made of many differing fre-
quencies could be severely distorted in transmis-
sion due to the time difference of arrival of each
component at the output. The distortion caused
by this effect is called delay distortion and it is
the direct result of a non-linear phase shift char-
acteristic in the transmission medium. Since the
several components of a complex wave are un-
equally attenuated and delayed, the envelope
shape is distorted.
The effect of phase distortion on baseband sig-
nals can be illustrated by considering the trans-
mission of a 2000 bit-per-second data test signal
through a section of 22H88 loaded cable. Let us
consider the 2000 bps data signal composed of al-
ternate Is and Os. Such a signal is made up of
all odd harmonics of 1000 Hz. When this signal is
sent through the 22H88 section of cable only the
1000 Hz. fundamental and the third harmonic
will arrive at the output. All higher harmonics
will be eliminated by the filtering action of the
facility. These two components will encounter
phase shifts which are not proportional to their
frequencies. The output waveform will be dis-
torted both by the removal of the higher har-
monics and by phase shifts. This effect is illus-
trated by Figures 2-5 and 2-6.
The phase shift characteristics of one mile of
22H88 loaded cable is shown in Figure 2-5. Fig-
ure 2-6 shows the fundamental and third har-
monic of the input wave forms. Only these are
shown since all others will be attenuated severely
by the loaded cable. The frequencies IkHz and
3kHz are indicated by arrows on Figure 2-6. The
phase shift at IkHz is 0.5185 radians/mile and at
3kHz is 1.8084 radians/mile. If the cable circuit
is ten miles long the IkHz component will be
shifted 5.185 radians and the 3kHz component
will be shifted 18.04 radians. The output voltage,
neglecting attenuation, will be
62 = 3 Sin (27t lOOOt - 5.185 =
Sin (27t 3000t - 18.04)
Since the phase shift at 3000 Hz is not three times
the shift at 1000 Hz the third harmonic com-
ponent is delayed relative to the fundamental by
, _ 18.04 3(5.185) _ 2.529 radians
2tt 3000 OOOOtt radians/sec
Td = 134 microseconds delay distortion
This value corresponds to the difference in veloc-
ity of propagation at the two discrete frequencies
for ten miles of 22H88 loaded cable. The wave
forms in and out of this length of cable are drawn
to scale in Figure 2-6. The waveform distortion is
readily apparent. Attenuation has been neglected
to emphasize the effect of the phase distortion
(delay distortion).
Non-Linear Distortion
Amplitude-frequency and phase-frequency
distortion as previously described are essentially
linear effects. They obey the principle of super-
position in that responses to individual inputs
add directly to form the response when the indi-
vidual signals are added to form a composite in-'
put. It is this property of linearity which makes
the resolution of signal waves into components at
different frequencies so potent a tool for analysis
and measurement. Transmission channels are
also subject to non-linear distortion. While good
design tends to make non-linear effects small,
they are a source of phase distortion and must be
considered in data transmission.
Worthy of special mention is a form of non-
linear amplitude distortion which can arise in
telephone channels having compandors. A com-
pandor consists of a pair of gain-adjusting cir-
cuits which act to maintain a more favorable sig-
nal-to-noise ratio over a line facility. At the in-
put of such a channel, one unit compresses the
amplitude of the voice signal. The narrowed
range enables transmission through a noisy fa-
cility at a relative high level without overload-
ing. At the channel output a complementary unit
expands the amplitude range to that of the orig-
inal input. The action is not instantaneous but
is governed by the envelope of the signal waves
over a time comparable with the duration of a
speech syllable. The variable gain in the two cir-
cuits is designed to have equal attack-time char-
acteristics to preserve the original voice wave-
form. However, the compression and expansion
may not be exactly complementary, and the re-
ceived waveform may, therefore, be different
from that originating at the transmitter terminal.
Such effects may inpair data signals, particularly
high-speed AM signals, even though voice sig-
nals would not be noticeably affected, (to be con-
tinued next month)

Alabama-Mississippi Approves
Merger for Exhibit Purposes
By John G. Reynolds
Publisher
Meeting at the Admiral Sem-
mes Hotel, Mobile, Ala.,
members of the Alabama-Mississip-
pi Independent Telephone Associ-
ation approved plans for the con-
solidation of their annual conven-
tion for trade show purposes with
one or more neighboring telephone
associations.
Presenting plans for the consoli-
dation, Joseph D. Fail, first vice
president of the association, ex-
plained Were not trying to com-
bine the associations. Each associa-
tion will have its own annual busi-
ness meeting and continue to have
its present identification.
Our plans, Fail said, envision
a three or four-state trade show,
patterned after the very successful
Western Conference and known as
the Southern Conference. We be-
lieve the regional concept of tele-
phone industry trade shows must
come. It will produce larger confer-
ences and provide larger audiences
for the suppliers and exhibitors.
Voicing her approval of Fails
comments, Mrs. Jean S. Brandli,
president of the Alabama-Missis-
sippi association, emphasized that
Suppliers prefer the regional con-
ference plan, and urged member-
ship approval of a program that
will take several years to accom-
plish.
The suggested regional confer-
ence plan was approved by a vote
of 16 to 3, with W. S. Howard of
the Tennessee Telephone Associa-
tion reporting the tentative ap-
proval of the Tennessee group.
Leading off the first general ses-
sion of the Alabama-Mississippi
convention, Charles E. Nahabed-
ian, of Bell Telephone Laborator-
ies, reported on new communica-
tion developments and the methods
used to improve telephone service.
We are studying present equip-
ment and their components, he
said. Included in our overall ob-
jectives are: (1) Transmission im-
provement; (2) new services that
will give the customer a telephone
that will do more than transmit and
receive voice signals.
Explaining that communication
is developing from person-to-per-
son contact to machine-to-machine
contact, Nahabedian stated We
have only scratched the surface of
the Picturephones capabilities and
versatility. Although, today, we say
the telephone is the next best thing
to being there, the Picturephone
will soon take over many of the
communication jobs that customers
are demanding.
USITAs Director of Settlements,
James T. Naylor, appearing as the
second general session speaker,
urged company-by-company par-
ticipation in present nation-wide
studies of separations. Reviewing
the early years of toll settlements,
Naylor defined settlements as the
amount of cost that passes from one
company to another and credited
USITA and the Bell System for
the progress made in the area of
toll settlements.
Addressing the final general ses-
sion, William L. Chappelle of the
U.S. Department of Labor, urged
the managements of telephone
companies to take their questions
and problems direct to the depart-
ments representatives.
It is our wish, Chappelle said,
that companies will contact us and
seek answers to their problems.
Some businesses are under the im-
pression that the Department of
Labor makes investigations. This is
wrong. Call us when you need help
and we will help.
The final convention speaker,
Mrs. Juanita McDaniel, of the Ala-
bama Public Service Commission,
told the conventioners that the
majority of people believe theyre
being represented by the commis-
sion only when rate increases are
turned down.

the Independent telephone indus-
try, Mrs. McDaniel said Indepen-
dent telephone companies serve
over one-half of the geographical
area of our country. Your average
investment per phone is $605 and
your average revenue per phone is
$143. Since I960 the growth rate of
the Independents has surpassed the
Bell growth rate. This is staggering
growth and you are responsible for
it.
Concluding the three-day ses-
sion, President Brandli urged the
association to (I) create a strong
Legislative Committee; (2) con-
sider two-year tenns for the associ-
ations officers; (3) develop a pro-
gram that will encourage the atten-
dance and participation of PSC
members at schools and seminars
conducted by the telephone indus-
try; and (4) encourage its mem-
bers to invest in the new REA Tele-
phone Loan Bank.
The greatest demand for loan
funds remains in the southeast,
Mrs. Brandli reported. And the
greatest financial support for the
bank should come from the south-
east. Stock can be purchased now
and it is a proper investment for a
REA borrower...

80-Line Electronic PABX Uses TDM Switching
A systems engineering study and exploratory development
progi-am undertaken in mid-1968 by Bell-Northern Re-
search of Ottawa, Canada, to define in detail the require-
ments for future PBX systems has resulted in a new 80-line
electronic PABX that draws many of its advantages from
the use of time division multiplex switching.
According to Tony Stansby, manager of PBX develop-
ment, Although TDM switching has found previous ap-

Figure 1. Principles of telephone switching by time-division multi-
plexing (TDM) combined with pulse-amplitude modulation (PAM).
As a first step the analogue telephone signals (1 and 2) are sam-
pled by sampling pulse trains (3 and 4) and converted into pulses
at fixed time intervals. The strengths of the analog signals are
conveyed by varying the amplitude of each pulse. Thus numerous
analog signals can be combined into a composite digital signal
(5), which is sent over the speech highway. At the receiving end,
the original waveforms are regenerated by extracting the two
pulse trains (6 and 7), and low-pass filtering (8 and 9).
plications in military communications equipment, in No. 1
ESS and in intercom equipment, the PULSE EPABX is
the first self-contained PBX based on the TDM principle.
Explaining various phases of development, Stansby said
that Electronic switching techniques, both space division
and time division, were evaluated and shown to be capable
of realization at lower cost than electromechanical switch-
ing networks using crossbar switches or reed relays.
He said that other factors favoring adoption of electronic
switching included: solid-state technology, which has
achieved reductions in cost-per-function; compatibility
with a solid-state common control from the network would
permit the economic inclusion of memory capability; and
greater flexibihty in growth of line and trunk capacity
would be possible because the TDM network could easily
be decentralized and physically distributed on a per-line
basis.
Tracing the technology behind the new EPABX, Stans-
by said, It was Claude Shannon of Bell Laboratories who
first pointed out that if a speech waveform, or any other
time varying function, is sampled regularly at a rate at
least twice that of the highest frequency component of the
function, then the samples contain all the information con-
tained in the original function. This means that the infor-
mation in a continuous waveform can be transmitted as a
series of short samples, and the time between samples can
be used to transmit samples from other waveforms. Figure
1 shows how samples of several waveforms can be obtained
and interleaved in time sequence on a single path, known
as the TDM speech highway. Any of the original wave-
forms may be regenerated by gating its samples from the
highway.
In the PULSE EPABX the voice information is con-
tained in the amplitude of the samples; this method is
known as Pulse Amplitude Modulation. The sample pulse
energy can be efficiently transfeiTed from transmitter to
receiver by making the resonant period of the transmitting
and receiving network elements equal to twice the dura-
tion of the sampling pulse. Thus, during the period when
the sampling switch is closed, all the energy stored on the
transmitting side of the resonant circuit flows into the re-
ceiving side and is then prevented from returning by the
opening of the switches. This technique is known as Re-
sonant Energy Transfer (Figure 2).
The central control consists principally of a single wired
logic control block including a 25-word recirculating mem-
ory. Each 48-bit word is permanently associated with a
time slot, and contains binary coded information on the
calling number, the called number, the state of the call
and other calling sequence information of the call in pro-
cess which is assigned to that time slot. As a word is shifted
out of memory, the logic circuitry is activated to direct the
necessary operation in the switching network and peri-
pheral units. After the word is read out and operated on,
it may or may not be changed in its configuration prior to
being read back into the input side of the memory. When
a call is terminated, the data in the memory word associ-
ated with that call are erased, thereby making that time
slot available for the next call. Continued on next page

A programmable diode matrix provides the class of ser-
vice for lines and trunks. This matrix is accessed by the
control logic to determine the kinds of calls in which any
particular line or trunk is allowed to participate.
The speed of control operation enables line scanning not
only for off-hook detection and supervision, but also for
dial pulse detection. Detection of dialed digits is performed
by scanning the lines, and, with appropriate timing mea-
surements, determining dial pulses and inter-digital times
for dialed number compilation. This approach replaces the
use of dedicated and traffic-sensitive dial pulse receivers.
Pulse reception is realized with a receiver dedicated to the
line during dialinga compact circuit package being
achieved by replacement of the LC filters by gyrators.
Transmission over the single TDM highway is realized
in a two-wire unbalanced configuration, added Stansby.
The time partitioning of the TDM highway is 25 time
slots in one frame interval, and each time slot is 3.33 micro-
seconds long. Twenty-four time slots are allocated for calls
in process, and one for scanning; hence, the system ac-
comodates up to 24 simultaneous telephone conversations
on the single highway, the frame interval is 3.33 x 25 =
83.3 microseconds. The switching capacity is 7.9 ccs (hun-
dred call = seconds) per line for the 80 line system where
40 percent of all originating calls are intercom, increasing
to greater than 30ccs per line at 20 lines. .
During the 3.33 microseconds time slot period, approx-
imately half the time is used for the interconnection of two
peripheral circuits (line to line, line to trunk or line to at-
tendant, and so forth). The remaining time is used to
clamp the highway to ground, thereby eliminating cross-
talk between adjacent time slots. The 83.3 microseconds

It is then prevented from returning by opening the switches.
sampling period (i.e. 12 kHz rate) ensures a high trans-
mission performance quality for voice or voiceband data.
During time slot Number 25 of each frame, one line is
scanned by the central control to determine its state, i.e.
on-hook or off-hook. This means that the scan rate for lines
in the maximum size system is one scan per 83.3 micro-
seconds X 80 = 6.5 milliseconds. If the scanning require-
ments for all trunks and lines are included, the worst case
scan rate is approximately 10 milliseconds for detection of
request for service.
The basic unit, which has a capacity of 40 lines and 15
trunks, includes the cabinet, five of the eight possible
equipment shelves, and the basic complement of printed
circuit cards which are common to all systems. Two addi-
tional connectorized equipment shelves expand the system
capacity to its maximum of 80 lines and 30 trunks. Option-
al service features are plug-in, and most can be installed
directly in the basic unit.

Thats our new PH circuit breaker. No
bigger than the PA breaker, it has the
highest AlC ratings of the Square D
molded case breaker line: 125,000
amperes at 240V., 85,000 amperes at
480V., and 65,000 amperes at 600V.
In addition, the PH has all the
quality features youve come to ex-
pect on Square D circuit breakers.
Its the most compact 2000 ampere
frame breaker you can get. The
breaker ratings can be changed with-
out disturbing any live partsa
Square D exclusive. The PH breaker
is UL listed, and can be fed from
either end. Naturally this better new
breaker has the exclusive push-to-
trip feature that lets you test the trip-
ping mechanism at any time. Also
available as factory installed options
are shunt trips, undervoltage trips,
bell alarms, auxiliary switches and a
motor driven operator. These are
factory installed so they can be ac-
curately and thoroughly tested under
ourown rigidly controlled conditions.
So, if youre looking for overcurrent
protection at the 2000 ampere level
as service entrance, branch device
or main disconnect equipment, look
into the up-rated PH circuit breaker.
