Conversely, the signal received from the antenna is amplified, down-converted to an IF and passed to the DAMA group or demodulated and passed as digital data to the user terminal. b. AN~SC-5(V). This UHF transceiver may be the same used for other subsystems. One of the eight channels supported is an OTCIXS network, DAMA or non-DAMA. Non-DAMA OTCIXS requires an OM-43A/USC. The modem PSK modulates outgoing signals received from the user terminal and passes an IF signal to the radio. For incoming signals the modem PSK demodulates the IF signal and passes digital data to the interconnect group. In DAMA operation PSK modulating/demodulating as well as multiplexing/demultiplexing is performed by the DAMA group and an IF signal is passed between the DAMA group and the radio. The radio converts the transmit IF t~ P~F and the receive RF to IF; amplifies the signal power to appropriate transmit or receive levels; and passes RF signals to and from the antenna group. 5-2.5.2.3 Antenna Group. With the AN/WSC-5 (V), the antenna group is the hybrid AN/WSC-5(V) antenna, its combiner group, preamplifier-splitter and diplexer. The combiner group combines up to eight transmit UH~ signals. The preamplifier-splitter amplifies and separates the receive UHF signals onto separate lines. Coupling/decoupling by the diplexer make's possible simultaneous transmission and reception of signals on the same antenna transmission line. With the AN/WSC-3, the antenna group may be a HR9NP, Andrew series, TACO H-084 or TACO H-124 tailored to the site. These antennas provide the function of radiating and/or capturing uplink/downlink signals. 5-2.5.3 Satellite. The UHF uplink signal is received, translated and radiated as the downlink. The downlink is than the uplink frequency on FLTSATCOM/LEASAT satellites FILLER. Satellite channels are designated for OTCIXS use DAMA operation by policy and designations could change on amplified, frequency offset 41 MHz lower and 53.2 MHz on GAPand for DAMA or nonshort notice.
5-2.5.4 Ship Satellite Terminal. The OTCIXS ship satellite terminal is either a DAMA or non-DAMA terminal depending on the physical installation. DAMA suites can fall back to non-DAMA operation. The OTCIXS network operates half duplex; however, the DAMA suite radio configuration may be full duplex. 5-2.5.4.1 Antenna Group. The antenna group is the OE-82B/WSC-I (V) or OE82C/WSC-I(V). It consists of an antenna control unit, RF switching unit, amplifier-filter(s) and one or two co-operating antennas on the ship superstructure° The antenna group combines or separates the transmit and receive signals and provides signal gain ~ith a preamplifier and by the inherent design. The ship's gyro provides signals to the control unit for azimuth tracking once the antenna(s) are initially pointed at the satellite (elevation controlled manually). The antenna(s) are installed so that at any time, view of the satellite is unobstructed by the ship superstructure. The antenna group may also be used for other UHF SATCOM applications. 5-2.5.4.2 Radio Group. The shipboard radio group is some version of the AN/ WSC-3. The radio must be modified for DAMA operation. The radio group may be configured as non-DAMA, DAMA with one radio, or DAMA with two radios. The TD1271B/U may operate half duplex (one radio) only with the AN/WSC-3A. With two radios, the TD-1271B/U operates full duplex even though the end application is half duplex. In non-DAMA operation the radio receives digital data from the user terminal and modulates the signal. In DAMA operation the radio receives AMENDMENT 0007 K - 12

Conversely, ~he signal received from the antenna is amplified, down-converted to an IF and passed to the DAMA group or demodulated and passed as digital data to the user terminal. 5-2.5.4.3 DAM~ Grou~. The planned functional DAMA group is the TD-1271B/U multiplexer. The TD-~27~B/U can operate with either a half duplex or full duplex radio configuration. A half duplex configuration allows for opera~ion of a maximum of three circuits (due to transmit/receive time slot contention), a full duplex up to four. The shipboard DAMA group performs the same functions as the shore DAMA group. It PSK demodulates and time division demultiplexes an IF signal received from the radio group and passes the separate signals along their respective routes. It multiplexes and PSK modulates a digital data signal received from ~he user terminal interconnect group and passes an IF signal to the radio group. 5-2.5.5 Ship Use~ Terminal. The OTCIXS ship user terminal is the AN/USQ-64 (V)7, which includes its ON-143(V)6/USQ interconnect group, and a TSEC/KG-36 cryptographic key generator or TSEC/KG-84 general purpose encryption equipment. The OTCIXS interconnect group provides automatic crypt~D synohroraization, store and forward of data and control of the OTCIXS satellite link. The C-11430/USQ control-indicator may be mounted on ~he ON-143(V)6/USQ front panel but is normally remotely mounted. Functionally, the ship user terminal is the same as the shore user terminal which is tabulated in Table 5-10. 5-2.6 TACTICAL DATA INFORMATION EXCHANGE SUBSYSTEM (TADIXS). (See F0-26.) All references to TADIXS in this manual address TADIXS A. TADIXS provides the capability to broadcast OTH-T data from shore sites to shipboard TDP systems in support of cruise missile operations. Implementation of TADIXS is being accomplished in four phases. In Phase I, a developmental communications system was used for satellite li~k testing of emerging TDP systems, in Phase II, OTCIXS replaced the developmental system and supported both OTCIXS and TADIXS functions. In Phase III, TADIXS is established as a dedicated link, apart from OTC!XS. In Phase IV, sophisticated gateways will be ins~ailed ashore to provide enhanced data routing and broadcast capabilities for TADIXS. Shipboard TADIXS terminals operate receive only and handle only TDP formatted data. Shore-to-ship, ship-to-ship and ship-~o-shore teletype formatted TADIXS messages and shipboard TADIXS tra.nsmissions take place via OTCIXS. DAMA implementation of TADIXS is under review. A non-DAMA TADIXS net will occupy I 25-kHz satellite channel. A DAMA TADIXS net will be multiplexed with other systems onto I 25-kHz satellite channel. 5-2.6.~ Shore User Terminal. The TADIXS shore user terminal is the USQ-64(V)8, which includes its own ON-143(V)6/USQ interconnect group, and TSEC/KG-84 general purpose encryption equipment. The TADIXS interconnect group provides automatic crypto synchronization, store and forward of TDP data and control of the TADIXS satellite link. a. Terminal Configuration. There are two types of shore configurations: broadcast sites and gateway sites. Broadcast sites interface wlth a peripheral TDP capable of both transmitting and receiving OTH-T messages. The TDP systems ashore create, generate and process OTH-T data, display processed data and pass data to and from a TADIXS interconnect group. The TADIXS IG for

the broadcast site also interfaces with ~ OTCIXS IG this allows OTH-T messages and data acknowledgements to be received fr~ afloat subscribers over the OTCIXS network. Gateway sites provide an interface between two adjacent satellite-coverage areas. Each gateway site is a subscriber in its own TADIXS net and an adjacent area TADIXS net; the two subscriber interconnect groups interface each other. A message addressed to a member of the adjacent area TADIXS net may be passed from one IG to the interfaced IG and then be transmitted directly on that net. Gateway sites permit worldwide exchange of messages using TADIXS. The C-11430/USQ control-indicator is normally mounted near the TDP operator's console to facilitate the entry of guard list parameters and to monitor the TADIXS link and ON-143(V)6/USQ status. b. Functional Overview. interconnect group. Network operation is governed by the
TADIXS
Network Timing. The network operates on a query/response net polling scheme. The current net operating speed is 2,400 bps.
(2)
Network Control. One shore subscriber in the net must be set as the Net Control Station. The net control function allocates link time to network participants as part of the net control discipline. The NCS sequentially polls each active net trans~ittero Sttbscrihers with data to transmit must wait their turn in the polling cycle and may transmit only after being polled. Time is periodically allocated to allow inactive subscribers t~ request they be added to the polling list (i.e., become active). Subscribers that do not respond to the poll after a specified number of tries will be removed from the polling list (i.e., become inactive). Network Operation. TADIXS network subscribers consist of a combination of shore broadcast and gateway sites, capable of beth transmitting and receiving, and afloat platforms, capable of receiving only. When broadcast data is transmitted the sending subscriber is immediately polled again for redundant transmission(s), Messages sent over the TADIXS link are currently limited in addressees to up to two subscriber identification number (SIDs) (although TADIXS will accept up to five). Receptions are screened for only those messages that are addressed to the subscriber's own unique three-digit SID and any other SID that may have been entered in the guard list. Each transmission received is checked for accuracy using the redundant transmission(s); a composite message is formed selecting the best elements of each transmission received° The data is then passed to the connected TDP.

a. AN_~SC-3. The AN/WSC-3 UHF transceiver may be configured as non-DAMA, DAMA with one radio or DAMA with two radios, The radio must be modified for DAMA operation. The TD-1271B/U may operate half duplex (one radio) only with the AN/WSC-3A. With two radios, the TD-1271B/U operates full duplex~ one radio transmits and ~he other receives, even though the end result is a half duplex application. In non-DAMA operation the radio receives digital data from the user terminal and modulates the signal. In DAMA operation the radio receives a multiplexed/modulated composite IF signal from the DAMA group. The radio amplifies the signal and passes an up-converted UKF signal to the antenna. Conversely, the signal received from the antenna is amplified, down-converted to an IF and passed to the DAMA group or demodulated and passed as digital data to the user terminal. b. AN~SC-5(V). This DqgF transceiver may be ths same used for other subsystems. One of the eight channels supported is a TADIXS network, DAMA or non-DAMA. Non-DAMA TADIXS requires an OM-43A/USC. The modem PSK modulates outgoing signals received from the user terminal and passes an IF signal to the radio. For incoming signals the modem FSK demodulates the IF signal and passes digital data to the interconnect group. In DAMA operation PSK modulating/demodulating as well as multiplexing/demultiplexing is performed by the DAMA group and an IF signal is passed between the DAMA group and the radio. The radio converts the transmit IF to RF and the receive RF to IF; amplifies the signal power to appropriate transmit or receive levels; and passes KF signals to and from ~he antenna group. 5-2.6.2.3 Antenna Group. With the AN/WSC-5(V), the antenna group is the hybrid AN/WSC-5(V) antenna, its combiner group, preamplifier-splitter and diplexer. The combiner group combines up to eight transmit UPLF signals. The preamplifier-splitter amplifies and separates the receive UHF signals onto separate lines. Coupling/decoupling by the diplexer makes possible simultaneous transmission and reception of signals on the same antenna transmission line.

The radio group may be configured as non-DAMA, DAMA with one radio or DAMA with two radios. Even though shipboard TADIXS operates receive only, a transmitter is still required to send DAMA ranging signals. In practice the other subsystems multiplexed with TADIXS use the transmitter also. The TD-1271B/U may operate half duplex (one radio) only with the AN/WSC-3A. with two radios, the TD-1271B/U operates full duplex even though the end application is half duplex. The signal received from the antenna is amplified, down-converted to an IF and passed to the DAMA group or demodulated and passed as digital data to the user terminal. 5-2.6.4.3 DAMA Group. The planned functional DAMA group is the TD-1271B/U multiplexer. The DAMA group receives an IF signal from the DAMA modified AN/ WSC-3, demodulates and demultiplexes the DAMA signal and passes the separated digital signal to the user terminal. 5-2.6.5 Ship User Terminal. The TADIXS ship user terminal is the AN/USQ-64 (V)8, which includes its ON-143(V)6/USQ interconnect group, and a TSEC/KG-84 general purpose encryption equipment. The TADIXS IG provides automatic crypto synchronization, store and forward of TDP data and control of the TADIXS satellite link. It also routes data between the TDP and OTCIXS IG for ship-toship and ship-to-shore data exchange over the OTCIXS link. The TDP systems aboard ship process OTH-T data received from TADIXS, display processed data, pass data to and from OTCIXS and, in some cases, pass data %o a weapon system. The c-11430/USQ control-indicator may be mounted on the ON-143(V)6/USQ front panel but is normally remotely mounted near the TDP operator's console. 5-2.7 SUBMARINE SATELLITE INFORMATION EXCHANGE SUBSYST~ ¯ (SSIXS) ¯ (See FO-27.) The SSIXS network provides a means for the transmission of message traffic from submarine-to-shore and shore-to-submarine. In addition, via the shore terminals, submarine-to-submarine capability exists. The subsystem is designed to provide a high-speed digital data communications link. DAMA implementation of SSIXS is currently under review; approved submarine equipment is not yet available. 5-2.7.1 Shore User Terminal. The shore user terminal is the AN/USQ-64(V)I and its interconnect group. Submarine Operational Control Centers (OPCONCENs) have at least one SSIXS terminal installed. Equipment redundancy is provided to limit the impact of equipment failures. 5-2.7.1.1 Interconnect Group. The SSIXS interconnect group is comprised of an ON-~43(V)4/USQ and a TSEC/KG-36 (or TSEC/KG-35) cryptographic key generator. The IG regulates the flow of the cryptographically protected data signal across the satellite terminal. The ON-~43(V)4/USQ can deal with SSIXS K- 16

Network Operation. Shore broadcasts can be scheduled (group), operator requested (special), or subscriber quested (response). At the beginning of a schedule, group broadcast message is prepared by the shore system and transmitted as the first message of the broadcast. This message lists all messages to be transmitted by subscriber priority and message precedence under each subscriber; a "No Traffic" notice is listed for those with no traffic. Subscriber operators will know from this summary message if any traffic in that broadcast is intended for them. A subscriber temporarily stores messages of concern in a buffer in the terminal computer. The shore terminal counts characters transm/tted to each subscriber during a broadcast; if the count shows the subscriber buffer to be full, a "More to Come" message is the final message sent to that subscriber in the scheduled period. A~y overflow traffic is transmitted immediately after the scheduled broadcast. If "there is more traffic than allotted time, a notice is sent and the remaining traffi~ is handled as overflow. If there is more time than traffic, extra time is filled by padding. When the broadcast is finished the net is available for query/response. Subscribers may randomly enter the net, send acknowledgments for messages received, send messages, or request other actions (such as FLTSAT NBSV service). Except if the query contains certain codes, any time a subscriber queries, the shore terminal automatically sends all unacknowledged traffic for that subscriber o The shore terminal automatically acknowledges messages received from a subscriber. Under control of the shore operator, a limited number of messages may be sent between subscribers (via the shore broadcast). satellite terminal is

b. Functional Overview. he suomarine terminal operator must know the SSIXS net schedule. Most message handling actions take place at specific operator command rather khan automatlcaily. AS a SSIXS subscrlber, the submarine termlnal receives broadcasm messages, automatically screens for ~hose addressed and ignores the rest. The operator will also know from the summary message whether a broadcast has any traffic for his submarine. The terminal can send messages to the OPCONCEN message'center, a limited number of messages ~o other subscribers (if permitted) or operator-co-operator one-line control er request messages. The subscrlber terminal uses a buffer in the computer to temporarily store incoming or outgoing messages. When the buffer is full, desired data must be printed before more data can be entered. If no additional data is to be entered (either send or receive), then the submarine may submerge and the operator can print the data later. Following the scheduled and overflow broadcast (if any), a subscriber with data to send may randomly enter the net (make a query) after the link has been idle six seconds and transmit its traffic or other message. If the shore acknowledgment for message traffic is not received within ]0 seconds, traffic is automatically sent a second time (if the net is idle). Unless certain codes are in the submarine's query, ~he shore terminal automatically transmits any unacknowledged traffic (or a "No Traffic" notice) to that subscriber following its query. 5-2.8 SINGLE CHANNEL TELETYPE (SC T~Y) SUBSYSTEM. (See FO-28.) The TTY network provides a means for 75-baud teletype messages to be transmitted ship-to-shore or ship-to-ship. This low speed network backs up the ship-toshore function of the CUDIXS/NAVMACS and TACINTEL networks. During SC TTY transition to DAMA, both DAMA and non-DAMA equipped ships will be able to communicate in a "merged net." Merged net operation is accomplished using a DSD in the shore satellite terminal. The SC ~TY operating concept is half duplex, "listen" before transmit. 5-2.8.1 Shore User Terminal. The shore user terminal is a TSEC/KW-7 cryptographic device and a Model 28 (or equivalent) teletype configuration which may vary but will include a reperforator. On the net, the terminal operator receives messages for relay and sends message acknowledgements and net control information. This terminal normally operates in the torn ~ape mode where an operator provides a physical interface to other systems such as NAVCOMPARS. The teletype terminal normally has a C-11 330/WSC-5(V) controlindicator mounted nearby. The terminal will also have either a KWX-8/TSEC remote phasing device or a C-8657(P)/UG teletype transmitter control (automatic phaser) for the TSEC/KW-7. 5-2.8.2 Shore Satellite Terminal. The satellite terminal for SC _~TY some configuration of the AN/WSC-5(V). A special DSD will be installed allow merged net operation during transition to DAMA. is
5-2.8.2.1 DAMA Group. The functional DAMA group is the TD-1271B/U multiplexer. The TD-1271B/U time division multiplexes the SC TTY signal into a composite signal and demultiplexes a composite signal into separate signals. The composite signal may contain multiple discrete signals. This equipment also PSK modulates/demodulates an IF signal. A multiplexed, modulated IF is passed to and from the radio group. The demodulated, demultiplexed signals are passed along their respective routes; in SC TTY, the signal goes to the user terminal cryptographic equipment.

5-2.8.2.2 Radio Group. The radio group is comprised of the AN/WSC-5(V) UHF transceiver, an OM-43A/USC PSK modem (in non-DAMA operation) and a C-11330/ WSC-5(V) control-indicator. This transceiver can support communications on to 8 sepa'rate 25-kHz channels. In non-DAMA operation the modem receives encrypted digital data from the user terminal and PSK modulates; or, in DAMA operation, a multiplexed, PSK modulated signal is provided by the DAMA group. In either case, an IF signal is passed to the radio where it is up-converted to UHI ~ and passed to the antenna group. The radio receives a UHF signal from the antenna group, down-converts, passes an IF signal to the modem or the DAMA group where it is demodulated (and if DAMA, demultiplexed) and passed to the user terminal as encrypted digital data. The C-11330/WSC-5(V) provides remote transmitter keying as well as signal acquired and transmit indicate lights. 5-2.8.2.3 Antenna Group. The antenna group is the hybrid AN/WSC-5(V) antenna, its combiner group, preamplifier-splitter and diplexer. The combiner group combines up to eight transmit U~F signals. The preamplifier-splitter amplifies and separates the receive UHF signals onto separate lines° Coupling/decoupling by the diplexer makes possible simultaneous transmission and reception of signals on the same antenna transmission line. 5-2.8.3 Satellite. The UHF uplink signal is received, amplified, frequency translated and radiated as the downlink. The downlink is offset 41 MHz lower than the uplink frequency on FLTSATCOM/LEASAT satellites and 53.2 MHZ on GAPFILLER. Satellite channels axe designated for SC ~Y use and for DAMA or nonDAMA operation by policy and designations could change on short notice. 5-2.8.4 Ship Satellite Terminal. The SC TTY satellite terminal is either a DAMA or non-DAMA terminal depending on the physical installation. DAMA suites can fall back to non-DAMA operation. The shipboard SC ~TY terminal configuration is normally half duplex. 5-2.8.4.1 Antenna Group. The antenna group is the OE-82B/WSC-I (V) or OE82C/WSC-I(V). It consists of an antenna control unit, RF switching unit, amplifier-filter(s) and one or two co-operating antennas on the ship superstructure. The antenna group combines or separates the transmit and receive signals and provides signal gain with a preamplifier and by inherent design. The ship's gyro provides signals to the control unit for azimuth tracking once the antenna(s) are initially pointed at the satellite (elevation is controlled manually). The antenna(s) are installed so that at any time, a view of satellite is unobstructed by the ship superstructure. The antenna group may also be used for other UHF SATCOM applications. 5-2.8.4.2 Radio Group. The shipboard radio group is some version of the AN/ WSC-3. The radio must be modified for DAMA operation. The radio group may be configured as non-DAMA, DAMA with one radio, or DAMA with two radios. The TD~ 27~B/U may operate half duplex (one radio) only with the AN/WSC-3A. With two radios, the TD-1271B/U operates full duplex even though the end application is half duplex. In non-DAMA operation the radio receives digital data from the user terminal and modulates the signal. In DAMA operation the radio receives a multiplexed/modulated composite IF signal from the DAMA group. The radio amplifies the signal and passes an up-converted UHF signal to the antenna. Conversely, the signal received from the antenna is amplified, down-converted to an IF and passed to the DAMA group or "demodulated and passed as digital data to the user terminal. The radio uses a remote C-9899/WSC-3 controlindicator that provides the operator remote keying and indicator functions. AMENDMENT 0007 K - 22

multi-
plexer. The TD-~271B/U can operate wiuh either a half duplex or full duplex radio configuration. A half duplex configuration allows for operation of a maximum of three circuir-s (due to transmlt/receive time slot contention), full duplex up to four. The shipboard D~MA group performs the same functions as the shore D~A group, it PSK demodulates and time division demultiplexes an IF signal received from the radio group and passes the separate signals along their respect-lye routes. It multiplexes and PSK modulates a digital data signal received from the user terminal cryptographic equipment and passes an IF signal to the radio group. 5-2.8.5 Ship User Terminal. Like the terminal ashore, the shipboard SC TTY terminal is a TSEC/KW-7 cryptographic device and some configuration of Model 28 (or equivalent) teletype which may vary but will include a transmitterdistributor. The C-9899/WSC-3 control-indicator is normally mounted near the teletype terminal as is a KWX-8/TSEC remote ~nasing unit for the TSEC/KW-7. The shipboard operator keys the transmitter using the C-9899/WSC-3, transmits messages on the net via the transmitter-distributor (and may make inquiries via the keyboard), and unkeys the transmitter when finished. Acknowledgements and net control information are received on a teleprinter. 5-3 DETAILED FUNCTIONAL DESCRIPTION, SHORE SATELLITE TERMINALS. This section contains detailed level discussions of satellite terminal functions covering the major control signals and signal data flow.
