SUBJECT Communications Requirements Determination
1. Attached is a draft of the Phase III Requirements
Determination Report. The report has been prepared over a.
period of several months, with the assistance of the members
of the Communications Requirements Working Group. It is
self-explanatory with Section I providing background infor-
mation and Sections II through VI (prepared as a separate
Annex for each Directorate) containing the comments, new
requirements and projections received during this process.
Review and validation of the report by members of the working
group and other appropriate component levels is requested.
Although L is i Cpoi L now i'eprt cents the present and
projected communications needs of the Directorates made
known to the Office of Communications, we hope that further
input in terms of future communications needs and long-range
projections can be developed by the working group. We again
welcome any comments you may wish to include in your response.
3. The purpose of this determination report is to
provide the Office of Communications with a comprehensive
compilation of the Agency's communications needs in the areas
specified to be used for planning purposes. Changes in
communications service will continue to require a specific
request with the approval of appropriate authorities.
4. This exchange will constitute the final review and
validation of the attached document. New information re-
ceived will he incorporated in this document and copies
distributed for reference information and planning purposes.

A. Purpose
The Office of Communications has been charged
with determining the information and digitized data
communication requirements of the Agency and, as appro-
priate, the Intelligence Community. The purpose of such
a determination is to ensure that those requirements are
met by the Office of Communications in a timely fashion
and to permit that Office to ensure the appropriate pro-
gramming of the required assets.
Periodically, either on their own initiative or
in response to queries from the Office of Communications
or the Deputy Director for Administration, various
Agency or Intelligence Community components levy require-
ments on the Office of Communications for support to
individual programs or units. The possibility exists
for requirements-to be overlooked or to become known only
in a time frame not conducive to support in the most effec-
tive manner. The present requirements determination will

cation needs are known and. met, both individually and
collectively, and that they are met with the most effi-
cient use of resources. Thus, the study should be of
benefit both to the supporting Office and to the com-
ponents possessing the requirements.
A thorough understanding and review of the
communication requirements is especially desirable at
this time. Reduction in the number of Agency personnel
overseas has, in some instances, resulted in a transfer
of support functions from overseas to Headquarters with
a resultant increase in communication requirements for
support information. Efforts, both by this Agency and
others, to convert increasing percentages of their report-
ing from dispatch to electrical form result in yet other
increased requirements. The increased use of automatic
data processing in the day to day business of the Agency
with the proliferation of remote computer terminals in the
Headquarters area creates a whole new set of problems. The
growth of data. communications, until recently very limited
in scope, requires greater attention to the support of that
area. The need to improve personnel productivity overseas'
by precluding multiple keying and manual media conversion

of material to. be transmitted electrically requires the
application of new technology in several areas including
communications. Developing requirements for near real
time exchange of data between remote locations and Head-
quarters and for bulk transmission of data also present
new problems. The need to support such diverse and in-
creased requirements with severely limited assets makes
it necessary that those assets be utilized as effectively
as possible. The planning effort in that direction is
well served by early and thorough knowledge of the full
range of communication requirements.
B. Scope
This requirements determination is concerned
with the staff narrative message, data transmission,
voice, facsimile and video areas. Video requirements
surfaced thus far have been very minimal and therefore
are not addressed as a. separate category. Instead,
they are addressed with the data transmission requirements
in Section II.A. This requirements determination does

or covert communications. Communications mechanisms
supporting these requirements are recognized as a vital
function of the Office of Communications, but the require-
ments themselves are (and in many cases must be) deter-
mined by other means.
Requirements of the Agency itself are addressed
comprehensively. Requirements of the Intelligence Community
are addressed where the Office is charged with providing
support or where the element is housed in Agency facilities,
e.g., the Intelligence Community Staff.
For purposes of this study, the term "narrative
information" is used to denote communications which are
generated by and/or intended for use of a human, i.e., -
read-able narrative material. The term "data" is used to
denote communications which are generated by and/or in-
tended for input to a data processing system, i.e. -
digital ma-,:trial.

This report does not address the mechanisms by
which the Office of Communications supports the require-
ments. It is intended to be a compendium of the require-
ments themselves.
The means of satisfying those requirements vary
from the provision only of secure transmission means, with
the customer providing and operating the terminal equip-
ment, to the provision of media conversion, retrieval
capability, transmission continuity assurance and other
diverse services.
This requirements determination is being conducted
in three phases. Phase I dealt with those requirements
which were the object of already existing or planned
communications systems. Due to the nature of those require-
ments, the Phase I Report was performed largely within the
Office of Communications. It was then forwarded to all
Agency components for validation and comment via their
individual renresent.ativeq to the C.npimii-i tinnc Regnire-
mor,ts Working Group. Phase ii of the
deiCtlll -LilaLioii
addressed those requirements projected by the Office of
Communications or recently developed by users but not yet
addressed by existing or planned communications systems.
Due to the long period of time required for most Agency
components to conduct an in depth r?view of their present
and future communications requirements, and fully
coordinate their responses, the users were requested to
provide long range projections on future communications
requirements at the time they validated the Phase I
Report. This effectively served as a means to gather the
information necessary for the Phase II portion of the
requirements determination. The comments, new requirements
and projections received during this process, as well as
the secure voice survey, have now been incorporated in
this report. Phase III, the subject of this report, will
serve as a validation process of all listed requirements
identified thus far. In addition, 'I-t. again serves as a
solicitation. from all Agency components for information
concerning requirements which may possibly exist but
which heretofore have not been statE.d and/or additional
information concerning requirements which have been pre-
viously stated but which have not been well defined 'or
quantified. Subsequent to completion of the final report,
the capabilities and plans of the Office of Communications

will be compared with the total requirements for communi-
cations support and recommendations may be made for
modification, elimination or addition of communications
programs.
D. Observations
Requirements often do not become defined until
the means of achieving them are available. Rapid develop-
ments in technology, either within or outside the
communications area, often make possible services which
are worthwhile but which were not previously requested
since they were thought to be unachievable. This often
limits the ability of customers to project or define
requirements beyond a short time frame.
Only in recent years have management
techniques been increasingly employed which permit and
often require longer range, more detailed, and better
quantified projections of requirements.
In the context of this communications requirements
determination, the observation of a frequent lack of firm
LL'in t. 1V11 d11U 1tU0.1141111.R41U11 L. 11C1 X17 is not V Ll vYca as
a negative result. Rather, it is viewed as a validation
of the desirability of the current review and the probable
usefulness thereof, both initially and on a continuing
basis.
E. Requirements Considerations
There are many means by which communications
requirements can be characterized, even when fully defined
and quantified. These include the broad categories of
volume of information to be handled, the medium in wich
the information must be accepted by and output by the
supporting system, and the criticality and sensitivity
of the information.
In unique instances, due to the need to inter-
face with existing systems or for other technical reasons,
the requirement as levied by the customer is quite specific.
with respect to speed of transmission, information code
employed, link control procedures or similar technical
parameter- More characteristically, the requirement can
and should be stated in terms of tht. result desired, in-
cluding liriting factors only to the extent necessary,
leaving to the technical support office the discretion
of determining the precise means of assuring that result.

In this manner the technical competence as well as the
available and developing assets of the supporting office
can best be used.
An almost universal requirement parameter is
information or data volume. It is frequently not one
of the more vital considerations when the supporting
mechanism is a totally new system. In that instance,
while the volume consideration affects the sizing and
cost of the system, it often does not impact greatly on
the technology required or the difficulty of satisfying
the requirement to the extent that the information medium,
criticality, sensitivity and end use do. It is, con-
versely, of great importance in imposing additional
workloads on existing systems which may result in a need
for significant modification or even replacement of a
system before its obsolescence.
It is thus vital that newly developed support
systems be sized to accommodate not only current volumes
but also reasonably predictable increases. This can best

practice the art of long range planning to the maximum
feasible extent and provide their requirements to the
support component, even in rough.form, at the earliest
possible time. The support systems can then be developed
with sufficient flexibility to accommodate future expansion.
Due to the variety of means of which communications
requirements can be characterized, and since the needed
specificity of the requirements varies greatly with the
particular application, the compilation of communications
requirements in Section II through VI of this report
contains varying degrees of detail and varying numbers
of parameters.

SECTION II - DIGITIZED DATA COMMUNICATIONS REQUIREMENTS
The following requirements are those considered
to fall within the broad area of communications generated
by and/or intended for input to a data processing system
rather than that of human readable narrative material.
A. Interconnection of Headquarters Building Remote
Terminal Devices with ADP Centers
THERE IS A REQUIREMENT FOR AN
EXTENSIVE NUMBER OF REMOTE
TERMINAL DEVICES LOCATED IN
USER AREAS TO COMMUNICATE
DIRECTLY WITH THE AGENCY ADP
CENTERS.
This requirement commenced with a series of
individual requests for the interconnection of various
remote terminal devices throughout the Headquarters
building with the several ADP centers. It grew to the
extent that it became necessary for the Office of
Communications to develop a standard means of vrovidine
si1C h GE?l"1T1 t'P, T_ p Headquarters Data Distribution Crid
system resulted. In preparation for that system, it was fore-
cast that remote devices would be installed in
the building through FY-1976 for information up to an in-
cluding TOP SECRET. This was accepted as a reasonable
projection. The Data Distribution Grid system, as installed,
has a maximum capacity of Oterminals. However a practical
capacity, due to clustering and other factors, is iI
The number of remote terminals installed has increased
from In FY-1969, to n FY-1971, to I un FY-1973,
to its present level o While certain portions of the
system are fully utilized, it continues to enjoy unused
capacity as a whole. Current projections by OC encompassing

all of the Agency's needs indicate that a maximum of = 25X1
terminals will be required by the end of FY-1975 and a
maximum of in FY-1976. The maximum data rate of the
Grid system in its present form is 9600 bps. In addition
to the Grid system several remote terminals requiring
coaxial cables, which the Grid system in its present form
cannot accommodate, have been provided on a one-for-one
basis.

B. Interconnection of Computer Terminals Located
at Various Locations in the Headquarters Area
Several Agency components located throughout the
Washington metropolitan area have requirements for data
exchange with ADP Centers located in the Headquarters
Building.
THERE IS A REQUIREMENT FOR A LIMITED
NUMBER OF DATA ACCESS CENTERS (DAC)
IN THE HEADQUARTERS AREA TO COMMUNICATE
WITH THE ADP CENTERS LOCATED IN THE
HEADQUARTERS BUILDING. THE UPPER LIMIT
COMMUNICATIONS SPEED REQUIREMENT FOR ANY-
SINGLE DEVICE WITHIN A DAC IS CONSIDERED
TO BE 9600. BPS.
DAC's were installed to meet the occasional data
exchange needs of components not having convenient access
to the Headquarters ADP Centers. They contain a variety
of equipment primarily intended for the transfer of quantities
of data too large for exchange via small, low speed remote
..Vim?nals and fo the use o components not possessing their
own terminals.
THERE ARE REQUIREMENTS FOR REMOTE
TERMINALS OF VARYING TYP'S LOCATED
1 THROUGHOUT THE WASHINGTON METROPOLITAN
AREA TO EXCHANGE DATA WITH ADP CENTERS
LOCATED IN THE HEADQUARTERS BUILDING.
THE UPPER LIMIT COMMUNICi~TIONS SPEED
REQUIREMENT FOR ANY SINGLE DEVICE WITHIN
ONE OF THESE REMOTE TERMINALS IS CON-
SIDERED TO BE 9600 BPS.
In addition to the DAC's covered above, numberous--
Agency components located outside of the Headquarters
,Building have specific requirements for exchange of
data with the ADP Centers within the Headquarters Building.
These requirements range from small, si:igle user, inter-
active terminals for accessing the Agercy's timesharing
system, to large special purpose remote computer terminals
which interface computer centers at their locations with
computers in the Headquarters Building.

C. Terminal and Control Switch and Resource
Allocator
THERE IS A REQUIREMENT FOR REMOTE
TERMINAL DEVICES TO BE AUTOMATI-
CALLY TERMINATED IN THE OJCS COMPUTER
CENTER, FOR THOSE DEVICES SINGLY OR
IN GROUPS TO BE SWITCHABLE FROM ONE
COMPUTER SYSTEM TO ANOTHER, AND FOR
QUALITY CONTROL TO BE EXERCISED AT
THE INTERFACE POINT.
The large and growing number of remote terminal
devices which must be interconnected with the OJCS com-
puter center greatly exceeds that which can be terminated
in any one of the six large scale computer systems in that
center. It also exceeds that which can be terminated in a
single front-end processor such as may be utilized in that
center. A need exists, in the event of failure of one or
more large scale computers or front-end processors, for
their workload to be switchable in whole or in part to
anothe. JySLe111. FULUce 11tuiLi-pUi1JUbe use of the 1.erniiiiais
further requires termination control. A further need exists
to be able to perform quality assurance checks and trouble-
shooting on the terminal circuits. That composite require-
ment is to be met by the OJCS Terminal and Control Switch
and Resource Allocator currently being defined by OJCS and
OC.
ACCOMMODATE AN EVENTUAL
REMOTE TERMINALS AND TO INTER-
FACE WITH UP TO SIX LARGE SCALE
PROCESSORS OR THREE FRONT-END
PROCESSORS. THAT IS CONSIDERED
TO BE THE CURRENT MAGNITUDE OF
THE REQUIREMENT.

D. Interchange of Data Transmissions Between
en Head uarters and Other Agencies and
Remote Locations
THERE IS A REQUIREMENT FOR THE
AGENCY HEADQUARTERS TO EXCHANGE
DATA TRANSMISSIONS ON A NON-REAL
TIME RECORD BASIS WITH DISTANT
AGENCY LOCATIONS AND WITH OTHER
AGENCIES AND CONTRACTORS. 1"1111
It is anticipated that in the not to / distant
future, Agency components may well have requirements
for the exchange of data with distant Agency locations.
One such OL projection is discussed at the end of this
section.
A relay function is required on the part of one
or more communications facilities to effect eventual delivery
from the originator to the recipient. Some transmission
originators or recipients are directly connected with the
Headquarters building data communications (DATACOM) facility
