General Information

The digital nonsecure voice terminal (DNVT) is a ruggedized field telephone. It is operable as a tabletop device in tents, shelters, and office environments. It also may be operated outdoors while strapped to a tree or pole. The DNVT is designed for durability to exposure of the elements during operation and transportation. Voice communication is accomplished through the handset. Digital data from an external device interfaces through the TA-1042A/U’s digital data port (DDP). The DNVT transmits and receives full duplex, conditioned diphase digital voice and loop signaling information at 16 or 32 kb/s rates. The

DNVT is a nonsecure telephone with no encryption capability. It digitizes voice information using continuously variable slope delta (CVSD) modulation.

Digital communication transmissions, both to and from the DNVT, are accomplished using a conditioned diphase

(CDP) data transmission method. This is accomplished by using the DDP. The DNVT operates in both common battery mode and local battery point-to-point mode, but not simultaneously.

General Information

The SB-22/PT and the SB-22A/PT are tactical, manual switchboards that can be rapidly installed to provide field facilities for interconnecting 12 local-battery telephone circuits, remote controlled radio circuits, or voice frequency (VF) teletypewriter circuits. Two

SB-22/PTs may be stacked to provide a 29-circuit capability by removing one TA-221/PT

(operator’s pack) and inserting five TA-222/PTs (line packs). Replacing a line pack with a trunk pack permits one-way ring-down, and one-way automatic trunk circuits between the

SB-22A/PT and any other switchboard with common-battery signaling. The Tone-Signaling

Adapter TA-977/PT provides the operator with a two-wire push-button tone-signaling capability for interfacing automatic switches without operator intervention.

General Information

The SB-3614 is a tactical, ruggedized, 30-terminal automatic switchboard. It provides rapid, cordless service to various interfaces. It may operate as a 30-terminal, single-switching facility or maybe connected with additional switchboards to form a 60- or 90-line system. The switchboard operator can monitor, answer, initiate, extend, preempt, and release calls using the four-by-four key sender and other functional push buttons. Any connection can be broken down manually, through operator intervention and action, or automatically, through a subscriber going to an on-hook condition. A maximum of 18 terminals may be connected as either four-wire DTMF signaling trunks, or DC closure dial pulse or DTMF trunks, ear and mouth (E&M) dial pulse or DTMF lines or trunks. The switchboards provide fully automatic operation with touch tone subsets and two- and four-wire trunks and limited service with rotary dial pulse subsets. The SB-3614(V)/TT requires manual tandem dialing when dialing outside of your local switchboard. The SB-3614A(V)/TT automatically routes the call through the network using primary or alternate routes. For common-battery signaling or ring-down lines and trunks without DTMF capability, the switchboard provides call extension service.

DTMF subscribers have direct distant dialing (7-, 10-, and 13-digit) and Defense Switching

Network (DSN), Dial Central Office (DCO), and commercial access capabilities. Other features of the SF3-3614A(V)/TT include facsimile service, call forwarding, preemption by precedence, conference calling, and subscriber (loop) hunting.

General Information

The CV-1918A(V)/G is a transistorized, eight-channel telephone signal converter designed to interface between automatic and manual telephone central offices. The

CV-1918A(V)/G and the automatic telephone central office communicate with each other using electronic signal tones. The operator’s actions are translated into signal tone commands by the CV-1918A(V)/G. When installed on either the SB-249TT/C or SB-1398/GTA-14(V) switchboard, the converter provides two-wire to four-wire and four-wire to two-wire telephone signal compatibility. In addition to establishing a voice path between the two different telephones, the CV-1918A(V)/G generates the tones required to activate the automatic telephone central office switching functions. The manual switchboard operator can dial into the automatic switch using the DTMF dialing capability on the CV-1918A(V)/G. The three

CV-1918A(V)/G models differ only in the quantities of components used in their configuration.

General Information

The AN/FCC-98(V) uses analog-to-digital (AD) conversion and pulse code modulation

(PCM) techniques to multiplex and demultiplex nominal 4 kHz analog VF channels for transmission over digital communications systems. It provides data interweaving by replacing

VF channel modules with selected data interleaving modules. It features full-frame acquisition and monitoring and performs AD conversions and time division multiplexing

(TDM). This set provides AD conversion on 3-, 4-, 8-, 12-, and 24-channel increments of 24analog VF channels. Digital data is interweaved into an output bit stream in time slots assigned to replace VF channels. Demultiplexer circuit modules demultiplex received digital data and perform digital-to-analog conversion required to reconstruct the original analog signal. Digital data is extracted from the input data stream and distributed to digital channels which replace VF channels. Built-in test equipment (BITE) is an integral test module that measures, tests, and monitors signals in and out of channel modules and of operation of various internal circuits, It also is used to isolate faulty channel modules and for alignment of replaced modules. Monitor and alarm circuitry give audible and visible alarm indications when there is a loss of frame or timing or failure to receive or transmit data for a nominal 100 milliseconds or more.

General Information

The AN/GRC-109 is a compact, portable high frequency (HF) radio set used for continuous wave (CW) communications under a wide range of climatic conditions.

Transmissions can be made using the built-in hand key, an external hand key, or an external, high-speed automatic keyer such as Coder-Burst Transmission Group AN/GRA-71. Two power supplies and a voltage regulator permit operation from a variety of power sources. Current tactical speech security equipment is not compatible with the AN/GRC-109; therefore, secure voice is not a mode of operation.

General Information

The AN/GRC-193 is a medium/high-power vehicular configuration of the Improved

High Frequency Radio (IHFR) system. It will satisfy those mission requirements which need an HF radio capability greater than the low power/IHFR system. The high-power vehicular/airborne adaptive configuration consists of a basic receiver-transmitter with required coupling device, amplifier, and other ancillary devices for CW voice or teletype operation; near vertical incidence sky wave (NVIS) antenna, whip antenna, data I/O device, and external power sources. The radio will have the capability of selectable power (100 W,

400 W). Normal operation will be below 400 W. The AN/GRC-193 uses the KY-99 for securing voice traffic and the TSEC/KG-84 for securing data traffic. The antenna may be remoted up to 61 m (200 ft) from the radio set, using the antenna siting bit which is part of the basic configuration.

General Information

The AN/GRC-213 is a low-power manpack/vehicular configuration of the IHFR system.

It provides a much needed, reliable, full HF coverage capability of 2 to 29,9999 MHz to tactical commanders. It has a requirement to pass secure, command and control information over medium to long distances and over varying degrees of terrain features which would normally preclude the use of very high frequency (VHF)/FM combat net radios (CNR). Use of broadband or NVIS antennas enhances the communication capability of IHFR. The

AN/GRC-213 consists of AN/PRC-104A (complete), audio amplifier and power conditioner, antenna switch (for use with long-wire antennas), and vehicular mounting tray to allow its installation in Army combat vehicles (tracked and wheeled). It gives the commander a complete low-power communications system.

General Information

The AN/PRC-74 is a low-power, transistorized, SSB radio set used for voice and CW communications. It is designed primarily as a manpack set in areas where direct line of sight

(LOS) communications are not possible. Except for the difference in the frequency range of the AN/PRC-74B and AN/PRC-74C, all models are essentially the same. Current tactical speech security equipment is not compatible with the AN/PRC-74; therefore, secure voice is not a mode of operation. Coder-Burst Transmission Group AN/GRA-71 can be used with all lettered models.

General Information

The AN/PRC-104A is a low-power vehicular configuration of the IHFR system. It provides a much needed, reliable, full HF coverage capability of 2 to 29.9999 MHz to tactical commanders. It has a requirement to pass secure, command and control information over medium to long distances and over varying degrees of terrain features which would normally preclude the use of VHF/FM CNR. Use of broadband or NVIS antennas enhance the communication capability of IHFR. The AN/PRC-104A consists of a receiver-transmitter with up to 20 watts of power, the associated accessories (microphone, antenna, battery, backpack), and the appropriate secure device. The AN/PRC-104A has a frequency range of 2 to 29.9999

MHz in 100 Hz steps yielding 280,000 channels and operates in the USB, lower sideband

(LSB), and CW modes. It provides the communications system.

General Information

The AN/PRC-112A(C) provides full voice encryption using Motorola’s field proven

INDICTOR module. Designed for covert and hostile environment operations, the AN/PRC-

112A(C) provides interoperability with key COMSEC devices including the Sunburst II

Processor (AN/CSZ-1A) and VINSON (KY-57). Slightly larger than the standard AN/PRC-112, the AN/PRC-112A(C) will slip easily into uniform pockets, rucksacks and other transport compartments. The AN/PRC-112A(C) is an NSA endorsed, Type I secure voice, ground-to-air communications radio. A mode control switch selects between two key variables for secure voice, a zeroize-key function and a clear “plain text” voice mode. This radio will automatically receive and process clear “plain text” voice transmissions even when configured in a secure voice mode. The built-in transponder beacon supplies ranging and personnel identification information via the airborne AN/ARS-6 interrogator system.

General Information

The AN/TRC-133A is a transportable, tactical HF, nonsecure SSB radio terminal set mounted in an S-280A type shelter. The shelter contains five radio positions which can be connected to separate doublet antennas provided as part of the radio terminal. Positions 1 and 2 can be operated with separated 15-foot whip antennas, which are used when the radio terminal set is needed for mobile operation and powered from the 28-volt DC vehicular electrical system. In addition, Radio Frequency Amplifier AM-3979/FRC-93 is provided to allow any one of the five positions to transmit on increased output power to extend the operating range of the position so selected. Current tactical speech security equipment is not compatible with the AN/TRC-133A; therefore, secure voice is not a mode of operation.

General Information

The AN/GRC-222 is designed as a short range wideband digital radio. The transmitter and receiver are tunable in 100 kHz steps over the 4.4 to 5.0 GHz frequency range. The modular design of the radio set reduces the amount of time necessary to troubleshoot and return the radio set to full service. If a problem occurs in a module, the procedure is to replace that module with an identical spare module. The faulty module is then returned to the factory for repair. The power supply module provides the DC power required to operate the radio set.

General Information

The AN/TYC-39(V) switch provides secure, automatic message switching of narrative record and data traffic at major corps and theater Army nodes in conjunction with multichannel LOS and demand assign multiple access (DAMA). The switch also includes tactical satellite communications (TACSATCOM), and tropospheric scatter communications media. This sheltered, tactically mobile equipment will be collocated with the AN/TTC-39 to provide circuit switching on data traffic as required. The difference between the models is in their cryptographic equipment. The (V)3 uses only integral TRI-TAC COMSEC equipment.

The other models can operate with TRI-TAC or inventory COMSEC equipment. The (V)3 is not in general field use because of the tactical need to interoperate with available terminal equipment. The 400 Hz design of the (V)4 fits it for use in aircraft or at US Air Force installations. The 50-line switch consists of two shelters: the communications interface shelter

(CIS) and the message processing shelter (MPS). The 25-line switch has both elements in a single shelter.

Technical Characteristics

The AN/TYC-39(V) automatically accepts, processes, stores, delivers, and accounts for narrative and data traffic through 50 lines, in ACP 127 and ACP 127 modified or JANAP 128 and JANAP 128 modified format only. Capabilities include processing multiple and collective addressed messages; mode, code, speed, and format conversions; handling six levels of precedence; message retrieval for retransmission; and message accountability and service functions. The AN/TYC-39(V) provides COMSEC for trunking and subscribers. Its interfaces include currently fielded record traffic terminals, modular record traffic terminals (MRTTs), modular tactical communications centers (MTCCs), unit level message switches (ULMSs),

Automatic Telephone Central Offfices AN/TTC-39, and DCS AUTODIN I. The AN/TTC-39(V) can interface with data adapters and the communications nodal control element (CNCE).

The AN/TCC-65 is an air- or vehicular-transportable PCM telephone terminal. It provides four 12-channel or two 24-channel two-wire/four-wire voice secure/nonsecure telephone systems. The AN/TCC-65 will be modified to integrate the TD-1065 high speed serial data buffer and the TD-1069 TDDM as part of the system. This adds the ability to transceiver high speed data in addition to radio. Due to space restrictions, two of the four

TD-754 cable combiners will be deleted. The TD-1065 will occupy the same space as the existing CV-1548s. Therefore, the new ability will be two 12-channel two-wire/four-wire voice; or two 12-channel four-wire voice/data; or two 24-channel two-wire/four-wire voice; or two 24channel four-wire voice/data. The AN/TCC-65 is used in the division and corps area communications systems.

Section V. Multichannel Satellite Communication Terminals

General Information

Satellite communications (SATCOM) systems have been used since 1967 to provide vital communications service to United States forces throughout the world. SATCOM has advantages which are not found in other systems:

SATCOM can provide reliable service without gaps in range or need for more than one ground relay station.

The SATCOM site does not have to be situated on high terrain or within LOS of the distant terminal.

SATCOM can provide thousands of voice and data channels originating at many ground terminals simultaneously.

SATCOM is multimodal. The ground station can transmit and receive numerous RF carriers simultaneously. Each carrier may be independent in source and in distribution from other carriers.

Set-up time for a new terminal, tactical or contingency, is very fast. Often, within one-half of an hour of arrival at a site, the terminal will be fully operational and communicating.

SATCOM consists of ground terminals and of one or more satellites. The satellite acts essentially as a repeater in the sky. It employs a transponder which receives, amplifies, and retransmits communications signals. Although a single ground terminal can only communicate with one satellite at a time, it normally has the capability to change from one satellite to another as required. The Army is currently involved in two major SATCOM programs:

The Defense Satellite Communications System (DSCS) program will provide global, strategic, multichannel communications to support the DCS.

The Ground Mobile Forces (GMF) program which is designed to provide singlechannel and multichannel communications for combat forces within a theater Army.

The chapter also discusses satellites and ground terminals currently in use or being developed to support the two programs discussed above.

6-64

FM 24-24

Defense Satellite Communications System Program

The DSCS's mission is to provide global communications capability to support the

National Command Authority (NCA)/Joint Chief of Staff (JCS) under the operational control of Defense Information Systems Agency (DISA). The US Army has the responsibility for the acquisitions and fielding of both ground terminals and SATCOM control equipment.

Modulation techniques include time division multiple access (TDMA), frequency division multiple access (FDMA), and spread spectrum multiple access (SSMA). Future modulation techniques will include demand assigned multiple access (DAMA).

The DSCS radio frequency portions are undergoing many upgrades to support its mission well into the 21st century. Some of the upgrades include:

Heavy/Medium Terminal Modification: This upgrade affects the AN/FSC-78 and

AN/GSC-39 terminals. These terminal’s RF components will be replaced with solid state devices for the transmitters and receive amplifiers. Included will be computer monitor, test and measurement, and control of the terminal functions.

Super High Frequency (SHF) Tri-band Range Extension Terminal (STAR-T): This developmental terminaI will replace AN/TSC-85B/93B terminals at echelons above corps

(EAC). The terminal will be mounted on a HMMWV. Its primary mission is to provide multiband communications and interface with commercial and military assets (dial central and satellite); DGM; TRI-TAC terminals at EAC; and with MSE terminals and ECB.

The DSCS Operational Control System (DOCS) controls all DSCS user terminals operating on DSCS spacecraft. This system also is undergoing upgrades that will allow higher control capability using less equipment and manpower resources.

The ground mobile forces (GMF) will use the DSCS II and DSCS III spacecraft to fulfill multichannel SHF initial system worldwide operational requirements. The DSCS II and III satellites are positioned in geostationary orbits and are continuously available for use by earth terminals located within 5,000 nautical miles of their subsatellite points. The

SKYNET IV satellite will be available for GMF use in Europe.

DSCS II:

These satellites have two transponders, each having a bandwidth constrained by the nominal 2009 MHz bandwidth of the total usable bandwidth of 410 MHz.

Each transponder is subdivided by filters in the RF diplexers to provide two operational channels, for example, four operational channels for each satellite. Four antennas are mounted on the despun platform. Two of them are earth coverage horn (ECH) antennas, one for uplink and one for downlink. The remaining two are parabolic dish type antennas. A single biconical horn is used to support the dedicated S-band telemetry and control link. It is mounted on the lower end of the spinning section of the satellite.

DSCS III:

The DSCS III program is a vital part of the comprehensive plan meeting national military communications needs. A six-channel communications transponder with each channel operating through its own RF amplifier serves the users.

This allows compatible grouping of users for efficient use of the SHF frequency spectrum of 7.9 to 8.4

GHz. The DSCS III satellite carries two communications payload packages. The primary payload is at SHF, satisfying the space link requirements of standard military communications networks. The secondary payload is an US Air Force SATCOM UHF single transponder used to transmit emergency action messages between military command posts

(CPs) and force elements. The communications system is supported by one receive multibeam antenna (MBA), two receive ECH antennas, two transmit MBA’s, two transmit ECH antennas, and a gimballed dish antenna (GDA). Each of the six independent repeaters operates in the SHF region to relay telephone, data, wideband imagery, and secure digital voice signals using FM, BPSK, quadrature phase shift keying (QPSK), staggered quadrature phase shift keying (SQPSK) and frequency hopping pseudo noise (PN) spread spectrum modulation. Each terminal has access to any channel and each channel can relay, with minimum performance degradation, signal transmissions consisting of FDMA, TDMA, and spread spectrum multiple access (SSMA) via the PN carrier modulation technique. Linear, quasi linear, and saturated modes of operation are provided by means of selectable gain steps.

The MBA with the beam forming the network can shape antenna patterns to arbitrary selected coverage areas.

General Information

The AN/FSC-9 terminals have been used since the earliest days of military SATCOM.

Two of these terminals were built and much of the research leading to the development of all present SATCOM systems (commercial and military) was conducted using these two terminals. The AN/FSC-9 terminal at Camp Roberts, California, is the only AN/FSC-9 terminal in operation and provides communications via satellite from the Pacific area to the continental United States (CONUS).

General Information

The AN/TSC-86 can provide simultaneous communications with up to four other terminals. Included in the terminal is modulation, demodulation, multiplexing, and signal conditioning equipment necessary for processing multiple, medium-, wideband-digital voice, data, and teletype signals. The electronics are housed in an S-280 shelter with mobilizer.

A power pallet containing two 30 kW generators is employed as part of the terminal. The terminal also consists of two antenna groups: the 8-ft group, AS-3036 and the 20-ft group,

AS-3199.

The communications subsystem accepts VF, teletypewriter, and baseband digital signaIs from external cable transmission networks and combines them with on board teletype and voice orderwire signals to form a composite, multiplexed, digital signal called the mission bit stream. This bit stream is applied to a bulk encryption device before routing to the digital data modem by the modulated 70-MHz panel for conversion to SHF and transmission.

Received signals are processed in a similar manner, except in the reverse order.

General Information

The AN/GRC-122 family consists of medium-power, vehicular-mounted HF-SSB radio sets used primarily for RATT operations; however, they are capable of AM and SSB voice and

CW operation. With the addition of a Navy standard one kW Radio Frequency Amplifier AM-

3924/URT and Antenna Coupler AN/URA-38A, the AN/GRC-122 becomes an AN/GRC-

122(V)2. This modified version provides the capability for long-range communications of

3,862 km (2,400 mi). The AN/GRC-122 and the AN/GRC-142 are both shelter mounted. The

AN/VSC-2 is mounted in a jeep and the AN/VSC-3 in an armored personnel carrier, The

TSEC/KY-65 (Parkhill) and the ANDVT (minimum term KY-99) will be used for secure-voice operation with the AN/GRC-106.

NOTE

: The only difference between the AN/GRC-122 and the AN/GRC-142 is that the

AN/GRC-122 has an additional receiver-transmitter and teletypewriter set allowing duplex operation.

MSE provides rapid, secure communications and has replaced the existing mix of

INTACS and ATACS communications equipment in the corps and division. It is designed to meet the requirements of a five division corps for a mobile, flexible, reliable, and survivable common-user area communications system. MSE system features meet the needs of the commander who conducts operations in war and operations other than war. MSE’s six functional areas provide a self-organizing network that includes automatic affiliation, deducible telephone numbering, and flood search routing techniques. These six functional areas are:

Subscriber terminal—consisting of telephones, facsimile terminals, and interface for data subscribers.

Mobile subscriber access—consisting of a mobile subscriber radio telephone terminal

(MSRT) that is equipped with a telephone terminal, a VHF radio, a data interface capability, and possibly with a facsimile terminal.

Wire subscriber access—consisting of large extension node (LEN) switches and small extension node (SEN) switches to be deployed at a call service position (CPS) to service static (wire) subscribers.

Area coverage—consisting of a node center (NC) switch, a radio access unit (RAU), and associated LOS assemblages which provide a tandem switched network and the interface between the mobile subscriber access and wire subscriber access functional areas.

System control—consisting of an automatic planning and management capability for MSE (including current system status).

Packet network—consistingof packet switches in a system control center-2 (SCC-2),

NCS, LEN, and SEN for data distribution.

MSE communications assemblages are in an S-250( )/G shelter mounted on an M-1037 high mobility multipurpose wheeled vehicle (HMMVW). The HMMWV can be transported by rail, ship, or air. All ancillary equipment (such as antennas, masts, cables, or reels) is mounted in or on the shelters or associated trailers.

A communications assemblage’s 30-minute set-up tear-down time enhances the mobility of MSE. Using back-up batteries provided in every shelter to power the systems for

10 to 15 minutes can reduce this time. The batteries are charged/recharged by the generator or the 200-amp kit contained in the HMMWV.

General Information

The AN/GRC-224(P) consists of an RF unit and a control unit. The RF unit includes a receiver and transmitter mounted on the two feet diameter parabolic reflector antenna. The control unit is a throw-on-the-ground component or can be mounted in the AN/TRC-190(V),

(V)1, (V)3, (V)4, and MSE switching assemblages. The radio set provides intra-nodal connectivity between the switch and LOS assemblages and reduces the RF signature at the command post (CP) location by using down-the-hill (DTH) application. The radio set offers convenient flexibility for simple and efficient network planning and frequency management.

The operating frequency range is 14,50 to 15.35 GHz divided into ten subbands. Transmit and receive frequencies in each subband can be seIected independently from between 29 (C/F

Band) to 49 (L/M Band) possible radio channels, depending on the chosen frequency plan.

General Information

The AN/TTC-46 LEN is configured in two S-250s, the Switching Group ON-305/TTC-

46 and the Operations Group OL-412/TTC-46. Each shelter is transported on an M-1037

HMMWV. The LEN is configured basically the same as the NC switch with basic differences in termination configuration for trunks and the LEN is not a tandem switch. The switching shelter provides the external interface, circuit switching and associated functions. The operations shelter provides the central processing and operator interface functions. The LEN performs all access switching and control functions for an MSE network. Power to both assemblages is provided by a PU-753/M, 10 kW, trailer-mounted, diesel generator set towed by the operation shelter’s prime mover.

NOTE: The following six configurations show the shelter layouts for all four versions.

General Information

The AN/VRC-97 MSRT consists of a VHF radio and DSVT. Depending on the mission, the AN/VRC-97 can be installed in one of nine US Army vehicles or used in stand-alone tripod configuration. Both the radio and the DSVT are designed to operate on the ground without protection from the environment. The radio transmits in the low band and receives in the high band and interfaces at 16 kb/s to the DSVT which provides secure discrete addressability. The radio front panel is accessible to the user for inserting COMSEC crypto variable and frequency fill. Inserting the personal code and the directory number is completed by using the keypad on the DSVT. Since the radio operates automatically, all subsequent calls, both initiating and answering, need only use the DSVT.
