.SECTION I - IN'i'RODtJCTIO\
A. Ptiz?pose
The. 0-Mice of Communications has been charged
with determining; the infer;nation and Digitized data
communicaticn reauirerents of the Agenc}' and, as appro-
priate, t}:e Intelligence Co,;ununity. The purpose of such
a dctermin~~tion is to ensure t}cat those reauirements are
met b}' 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 ar
in response to queries from the Ofi.ce of Communications
or the Deputy Director, for Administration, ;carious
Agency or Intelligence Community corlponents levy reauire-
ments on the Office of Communications for support to
individual programs or units. The possib:~ii.ty exists
for reauirements to be overlooi;ed or to become i;r~own only
in a Limo frame not conducive tc support i.n t}"ie most effec-
tive manner. '?'he present requirements determination will
be beneficial in assuring t}cat-the broad range of communi-
cation needs are known anct met, both incliviciually and
collectively, and that they are met ~~;ith the mast effi-
C1e7lt use of resources. Thus, the stud}r s}could be of
benefit both to the supporting Office and to the com-
ponents possessing the reauirements.
A thorough tinderstandi'zg ar_d revie~e of i.he
communication reauirements is especially desirable at
this time. Reduction in the number of Agency personnel
overseas has, in some instances, resulted in a tx~zZlsfer
of sut;port functions Pram o?~rerseas to Iieadauarters .with
a resultant increase in ~ommuni.catic;i r~uuiremer.ts.for
support information. Efforts', both by this Agency ar~ci
of}~ers, to convert increasing percentagos of their report-
ing from dispatch to electrical form result in yet ot}ier
increased rcc{uira;l;.ents. Tl;e increased s~se of automatic
data processing in the day to d,zy business of the F:gency
wit}1 the proliferation of re,:~ote corir_ut.er tzrminals in the
fleadau..Lrtcrs area creates a i~hcle ne~~ set of problems. '?'he
growth of data cc^lr,;unicatio~~s; ul~tii r~ccntly very limited
in scope, reaiaires ;reat~r attention to t}~e sup>>or.t of t}gat
area. The need to improve person;ial -orD~ductivity overseas

of material to be transmitted electrically requires the
application o~l ne;~ tec:hnolo;gy in se~reral areas i nc? udinl;
COIllrllllI11C=1t"lens. Developing requirements for near real
time exc};an4;e of data b~.,~t;ti~een re.?ate locations a.nd Head-
quarters and for bulk t;?~ansrni5si.on of data also present
new problems. The need to :~ul?port such diverse and in-
creased requirements ;with severely limi ted assets ;makes
it necessary t}.at those assets be utilized as effectively
as possible. The plannin effort irz tha~~ direction is
well served by early and thorough knowledge of the full
ranbe of communication requirements.
B. Scope
This requirements determination is.ccncerned
with the staff narrative message, da-La transmission,
voice, facsimile and video areas. 1'ideo reouirements
surfaced thus far have been very minimal and therefore
are not addressed as a separate category. Instead,
they are addressed ;with the data transnlis:sion rpqu`irements
in Section II.A. This requirements determination does
not address certain compartmented prr~jec4 requirements
or covert commz.zni.catiolis . Communications meC}1~tIZ1SIns
supporting these requirements are recaanZGed as a ~rital
function of thu Office of COlllnlunlcatlo.is, but the require-
ments thems?l.vcs are (and in many cases must be} deter-
mined.by other means.
Regtzirem'ents of the Agency itself are addressed '
comprehensively. Requiremer_ts of the Intelligence Community-
are addressed where the Office is charted ;~~ith providing
support or ;where the element is housed in Agency facilities,
e.g., the Intelligence Community Staff,
Fox purposes of t}~iis study, th? term "narrative
information" is used to denote communications k-hich are
generat:cd by and/or intended for use of a human, i:.e. , -
readable narrative ;naterial. The ~ernl "data" is used to
denote corrmunicafiions w}_ich a-re generated by and/or in-
tended for input to a data processing system, i.e. -

This report does no< ac'.dress the mechanisms by
which t}lc Office of Ccinrn~unic~~ t ions sup}?ort:s the require -
ments. It is intended to bo ri compendium of the require-
mei:ts themselves.
The Ttieans of satisfying-those requirements vary
fron, the pro~ri.sion oni}- of secure transrn:issior. means, with
t}le.customer providing and operating the terminal equip-
ment, to the provisior. of media ccnversicr,, retrieval
capability, transmission continuity assurance and other
diverse services.
C. Method
This requirements determination is being conducted
in three phases. Phase I dealt ti~~ith those reauireraeilts
which were t}ie object of already existing o-r planned.
communications systems. Due to the nature of t}rose require-
ments, the Phase I Rer.ort was performed largely within the
Office of Communications. It was then fai?warded to all
Agency components far validation and comment via their
individual representatives to t:he Communications Require-
ments titi'orl:ing Group. Phase II of the determination
addressed those requirements projected by the Office of
Communications or recently developed by users but not yet
aclclrersed by existing or planned communications systems.
Due to the long period of. time required far most Agency
components t.o conduct a;i indepth revie~~r of their present
and i'uture communications requirements, and fully
coordinate their responses, the users ti~ere requested to
provide long range,proje:ctions on future communications
requi.rerr.ents at the time they validated the Phase I
Report. This effectively served as a means t.o gather the
information r.ece,ssary for the Phase II portion cif the
requirements determination. The commer_ts, nel~T requirements
ai:d projections received during this process, as ~ti~ell as
-the secure voice survey, have noz~; been incorporated in
this report. Phase II:i served primarily as a validation
process of all listed requirements although some new
roc{ui.rements iti~ere identified as hell as a feiJ minor modifi-
cations anr} corrections which have been included in .this
the I~'inal Report. The Office oz Conjmunications is presently
engagod in the planning, det~Teiopricnt, and. inszalation of
new commu~iications systems and the upgrading of presently
existing ~~systcrns -and services based on the infor;r:atiori
contained in this Report as ti~~ell as other sources. The
present calaabilities and plans of the Office of Coir~municatiens

are being compared i~~ith the total requirements for communica-
tions support .and reconanendaticr.s may be made for modi.fi;a-
tion, elimination or addition of communications programs.
D. Obscrvati.ons
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, open make possible services which.
are ti~~orthwhile but whicl: were not previously rcquc seed
since they were thought to be unachievable. This a}ten
limits the ability of customers to project or define
requirements beyond a short time frame.
Only ir_ recent years have management techrLiques
been increasir_oly employed whic}~ permit and often rt~quire
longer range, more detailed., and better quantified pro-
jections of requirements.
In the context of this communications requirements
determination,_the observations of a frequent lack of. firm
definiticn and quantification of needs is not vie~.ti~ec~ 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 Considerazion.s
There are many means by which communications
requirements can be characterized; even when fully
defined any auanti.ficd. These include the broad cate-
gories of volume of information to be har_dled, the
medium in which the information must be accepted by
and out}:ut by the supporting system, and the o'riticality
and sensitivity of the information.
In unique instancr.s, due to the need to inter-
face with existing syst:~~:~Ts or fo-r ot'ier tec}~nica]. reasons,
the requireme;it as levied by the cus~aTzer is quite speca.fic
with respect to speed of transmission, iniormatiori code
employed, link centre]. procedures or si*niiar technical
paramete`i?s. 'More characteristically, z}ie require?nent ca.n
and should be stated in terms of the result desired, in-
cluding limiting factors on]y to the uxte,rt necessary,
leaving to tl:e teehr,icwl support office the discretion
of determining they precise means- of- assurinz that result.

In this manner the techlt ica l con~pi~tence as 1.Te17. as the
availab3e end de?relnpin assets a:~ the supporting office
can best be used.
~n almost ur.ive;rsal requirement parameter is

the technology required car the difficulty of satisfying

criticality, sensitivity and end u.se do. It is, cor_-
versely, of sreat impart~~Iice in imposing additional
workloads on existir.R s~?~~te~ms lti~hich ma}' result in a need
for significant modi.iicat:ion ar even replacement of a
system before its obsolescence.
It is thus vital that ne"~ly devnloned support
systems be sized to accommodate pat on1}T carrent tiolumes
but also reasonably predictable increases. This can best
be achieved if components requiring ccr..s~unication_~ =unport
practice the a.rt of long range plannin, to the ma;:i^rtznl
feasi.}-sle etitent and provide their requirements to the
support co,:~~~onent, even in .rough forr.;, at the oar? lest
possible time. The support system_=. cr:z ti;en be devel.o~,od
with sufficient f.lexi.bility to accomr:adute future exrazsio_,,

SECTION II - DIGITIZED DATA CO1~S~iU\'ICATIONS RLQUIREAIENTS
The following requirements are those considered
to fall within the broad area of communications genexated
by and/or intended for input to a data processing system
rather than that of huma.ri readable narrative maaerial.
A. Interconnection of Headquarters Building Remote
Terminal Devi~~ith :},lil' Centers
TIIERE IS A RE~UIRE;~IENT FOR AN
1;?:Tk:NSIVE N11jIBER OF REMOTE
TERA4INAL DEVICES LOCATED IN
USER AP.EAS TO CO~Ii~IUNICATE
DIRI~CTLY 1VITII TIIE 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 st~.ndard means of providing such
service. The Ieadquarters Data Distribution Grid system
resulted. In preparation for that system, it ~?aas forecast
that rerr.ote devices would be installed irr '~}1e
building through FY-1976 for information up to and including
TOP SECRET. This tvas accepted as a reasonable projection.
The Data Distr.i.bution Grid system, as installed, has a
maximum capacity of Oter.minals. however, a practical r"-'
capacity, due to clustering and other factors, i.s
The number of remote -terminals installed has increased
from Qin FY-1969, to 0 in FY-1971, to Din l;Y-1974.
While certain portions of the system are fully utilized,
It ~GO11t1.nlle5 to enjoy unused capacity as a tivhele. Current
projections by OJCS encompassing ail of the Agency's needs
indicate that a maximum of Oterminals will be required
by the end of FY-1975, a rnaxirnum of 0 in FY-1976, and
a maximum of 0 in FY-1977. .'The maximum. data rate of the
Grid syste;n in its present form is 9600 bps. In addition
to the Grid system several. remote terminals included in
the above projections, renuirirg coaxial cables, which the
Grid system in its .present forr~ cannot accommodate, have
been provided on a one-for-one basis.
