ABSTRACTBased on a needs assessment of intra-state and
inter-state interconnection telecommunication services the VirginiaPublic Telecommunications Council (VPTC) envisions a pUblic servicesatellite system consisting of: (1) primarily broadband transceivercapacities to areas having state supported institutions of higher
cosse.s.carrier-smpplisd..n&rrotg?hala. ,extensions to various state agencies; and (2) narrow-band transceivercapacities located in areas lacking institutions of higher educationbut having a School Division Headquarters, with narrow-bandextensions (common carrier supplied) to various state agencies. This
---system-would-Interconnect-directly-w±th-compatible-transceiverswithin satellite range. Traffic protocols would be centrally managedfrom Richmond and coordinated with the national satellite operatingauthority. (DAG)

We envision in Virginia a PUBLIC SERVICE SATELLITE SYSTEM which consists of:
(a) primarily, broadband transceiver capacities in those 31 Virginia
"locality clusters" having state-supported institutions of higher
education, perhaps with common-carrier-supplied (or radio-spectrum)
narrow-band extensions to each nearby School Division Headquarters,
DMV local office, Highway Department Depot, State Hospital facility,
local hospital, Corrections installation, Health Department Office,
Welfare Office, Environmental Monitoring facility, Employment Office,
Public Telecommunications Entity*, public radio station**, State Police
Headquarters as well as the principal sites of local government and local
law enforcement administration. In those 8 localities where there are
several institutions of higher education in close vicinity, broadband
links can be used to inter-connect them with the nearby transceivers.
(There are 16 such installations in all).
(b) perhaps also, narrow-band transceiver capacitieS in all or certain of those
52Virginia '!locality clusters" lackIng-an-institution-of higher-education--
but having a School Division Headquarters,with common-carrier-supplied
(or radio spectrum) narrow-band extensions to each nearby DMV local
office, Highway Department Depct, State Hospital facility, local.
hospital, Corrections installation, State-owned radio station, Health
Department Office, Welfare Office, Environmental Monitoring facility,
Employment Office, State Police Headquarters as well as the principal sites
of local government and local law enforcement administration.
*The five regional Public Telecommunications Entities would actuallyprovide suitable broadband links from their Master Control Roams to andfrom the closest transceiver sites.
**Similarly, CPB-qualified public radio stations in Richmond, Norfolk, Roanoke,Harrisonburg and Fairfax would provide high-fidelity, audio-bandwidth linksto and from their own Control Rooms.
N.B. Broadband and/or narrowband extensions could also often be accomplishedthrougf local CATV systems.
'7
The regional multiplexing broadband facilities would be employed to
receive, send and relay duplexed video (cinematized), high fidelity or
voice-grade audio (including various slow-scan video formats), high-speed
and slow-speed data (including facsimile, telemetry, servo and alarm
signals).
The local limited-multiplexing narrowband capacities would be employed
to receive, send and relay duplexed voice-grade audio (including certain
slow-scan video formats) and slow-speed data (including facsimile, telemetry,
servo and alarm signals).
BTP terminal systems would include:
Video Monitors and/or recordersHigh-fidelity Audio Monitors and/or recordersHigh-speed Facsimile Print-outs and/or copiersHigh-speed Computer Inter-faces
Parallel Telemetry Mechanisms and recorders
NTP terminal systems would include:
Slow-scan Video Monitors and/or recordersAudio Monitors and/or recordersSlow-speed Facsimile Print-outs and/or copiersSlow-speed Computer inter-faces ( including Teletypewriters)Alarm MechanismsTelemeters and/or signal recordersServo Control Mechanisms
Concomitant Origination_Systems would include:
Video Cameras and MixersAndio-NAdeo reCorderSiOlayback machinesMicrophones and Audio Processors/MixersAudio recorder/playback machines and Rate Change DevicesFacsimile Encoders (Micro-form and other)TeletypewritersKeypunchers and ReadersCathode-ray writers and similar electro-optical device systemsData recorder/playback machinesEnvironmental Sensors and Meters (Heat Light, Chemical, etc.Stress and pressure sensors and metersSignal Activators (Manual and programmed)Computers (Digital or Analog)
Medical Sensor Instruments
9-7-
The envisioned Broband interconnection system would likely requare:
(a) 2 hours of broadband single-channel service between 8 a.m. and
5 p.m. each workday.
(b) 2 hours of broadband single-channel service between 5 p.m. and 11 p.m.
each weeknight.
(c) 2 hours of broadband single-channel service between 11 p.m. and 8 a.m.
each day.
If double-channel broadband capacities were made available, overall time
requirements might be halved.
Narrowband requirements would be:
(a) 24 hour instant access to an emargency channel
(b) 10 minutes per hour on a data conditioned channel (to be used largely
...in,a.p.olling.,....shareme.mo4P for critical update_relayin8).
(c) 2 continuoushours it, the 8 a.m. - 5 p.m., 5 p.m. to 11 p.m. and 11 p.m.
to 8 a.m..time periods each day.
(d) 1 minute in every 5 for relay of telemetered data on a conditioned channel
(to be used ih a polling, share-time mode)
All figures are minimums.
NOTE: It is presumed that Narrowband facilities would be devised and used
only where, and to the extent that, CCO-supplied circuits or con-
ventional microwave or radio links are unavailable, more expensive,
significantly less reliable, or technically inferior.
10
SYSTEM REACH
The envisioned intra-and-inter-state Interconnection System should be
designed to allow any Virginia Transceiver to interconnect directly with
any other technically compatible transceiver within satellite range but
under strict traffic protocols which are managed from a central organiza-
tional point in Richmond and which are in turn fully integrated with overall
traffic configurations determined by the national satellite operating
authority.
11
STRIICTURAL OUTLOOK
The VPTC believes that there is strong merit in the ronCept that the
five Public Telecommunications Entities in Virginia become jointly the
principal intra-state operators of the public service satellite system
elements described herebefore, interfacing them where logical with CCO and
state-owned radio-spectrum or computer facilities. Such an arrangement
might best be effected by having the entities incorporate with the VPTC
(acting on behalf of the Commonwealth government) as an ADDED VALUE NETWORK
ORGANIZATION (AvN0). In this way, the interconnection system would be
"synergized" through the regular accessing of media production, storage,
maintenance, design, and management resources.
The AVNO, centered at Richmond, would be responsible for clearing and. . . .
implementing all intra-state and inter-state switching protocols with the
national satellite operating organization.

PHASING PRIORITIES
Assuming the demonstrated cost-effectiveness of the capacities and
facilities to be involved at each installation phase, the VPTC tentatively
anticipates the following priority schedule for the development of the
iLterconnection system envisioned:
(a) Main BTP at Richmond interconnected through satellite to comparable
State BTPs elsewhere (but especially in the East)and BTPs at Norfolk.
Roanoke and Fairfax (4 BTPs)
(b) BTPs at Harrisonburg and Wise (2 BTPs)
(c) BTPs at Danville, Fredericksburg, Wallops Island, Williamsburg,
Farmville, Abingdon, and Charlottesville (7 BTP8)
(d) BTPs at Franklin, Warsaw, Petersburg, Alberta, Middletown, Lexington,
and Wytheville (7 BTPs)
(e) BTPs at Clifton Forge, Lynchburg, Richlands, MArtinsville,
Blacksburg*,Newport News*, and Leesburg* (4-7 BTPs)
(f) BTPs at Keysville*, Weyers Cave*, Dublin* and Glenns* (up to 4 BTPs)
(g) NTPs at Greensville County, Halifax County, Lee County, Highland
County, Louisa County, Culpeper County, Grayson County, Lancaster-
Northumberland Counties (8 NTPs)
(h) Other NTPs as required (up to 44 NTPs)
*Engineering studies might obviate need for these BTPs by extendingbroadband services from other locality clusters nearby.
