Signal Data Recorder-Reproducer
The RD-397(V)/U, figure 3-34, is used in baseband
equipment installations with CUDIXS, NAVMACS, and
TACINTEL (ship and shore). The (V)3 version is used at
SSIXS shore locations. This tape perforator/reader can
punch tape at 63.3 characters per second and read tape at
up to 300 characters per second. The equipment is self-
contained; that is, complete with control logic, buffering,
and power supplies.
Navy Standard Teleprinter AN/UGC-143(V)
The Navy Standard Teleprinter (NST) is the standard
teleprinter terminal set for surface platforms. The NST is
used for netted circuits and for broadcast, ship-to-shore,
and ship-to-ship communications circuits. The various
configurations of the NST provide for information
preparation, editing, printing and receiving of serial data,
and buffering and storage of information. An AN/UGC-
143A(V) 4 NST is shown in figure 3-35.

Audio Digital Converter CV-3333/U
The Audio Digital Converter CV-3333/U is called a
vocoder or voice digitizer. This unit is a solid-state, all-
digital speech processor, providing speech output at a data
rate of 2400 bps. It is capable of fill-duplex or half-duplex
operation, figure 3-36. It can be used to provide a single
digitized voice circuit, or have its output multiplexed with
other data-bit streams to provide simultaneous voice and
data transmission. It is used primarily as an analog-to-
digital converter in Fleet Satellite Secure Voice
Switching Unit SA-1704/UG
The Switching Unit SA-1704/UG is used in baseband
equipment shore installations of SSIXS, CUDIXS, and
TACINTEL subsystems. It is a passive patch panel that
shows the equipment configuration in use. Each
subsystem unit is slightly different. In CUDIXS, the
switching unit maybe used to switch in equipment from
the spare system; whereas in SSIXS, it is used to switch in
Switchboard is the planned replacement for this unit.
Time-Division Multiplexer TD-1150/USC
The TD-1150/USC time-division multiplexer is
installed at broadcast keying stations ashore. It is used in
the Fleet Satellite Broadcast subsystem and consists of
two units, one online and the other in standby. It accepts
up to fifteen 75-bps data channels and multiplexes this
information into a single 1200-bps output data stream. A
TD-1150/USC is shown in figure 3-37.
Multiplexer (DAMA) TD-1271B/U
The Multiplexer (DAMA) TD-1271B/U is used
in the DAMA subsystem and provides time-division
