external frequencies by at least 20dB (if the other
frequency is a 10 watt transmitter), and 30dB (if
the other frequency is a 100 watt transmitter).
2.3 Ordering Information
The TC–10B carrier is functionally compatible
with earlier type carrier equipment (e.g., KR, TC,
TC-10, TC-10A). That is, you may use the
TC–10B with these other carrier types at the
opposite end of the line, with or without voice
function. You may use the same telephone handset
unit with any of these ON-OFF carrier sets.
You may use the TC–10B carrier set with the
following types of relay systems:
• All Directional-Comparison Blocking
Systems
• Phase-Comparison Blocking Systems,
e.g., SKBU-1 (Requires 45-Vdc power
supply — please see Table 2-5.)
Simplified schematics of typical electro-mechan-
ical systems are shown in Figure 2-5 through
Figure 2-13 (schemes A thru K). These schemes
indicate the different jumper positions required for
particular applications. Simplified connections
between the TC–10B and a microprocessor based
relay are shown in Figure 2-14 (Scheme L).
Figure 2-15 shows the output circuit for micro-
processor based relays (1 amp maximum output).
Figure 2-16 shows the resultant output circuit for
48, 125, and 250Vdc systems.
Two variations of TC–10B are available:
(1) Plug-in Voice Adapter Module with signaling
as a push-to-talk maintenance voice channel -
(see Chapter 17). A telephone jack is provided
on the Voice Adapter Module, but you may
also use a remote jack or hookswitch. (See
Figure 18-4, Scheme J, for the connection
diagrams.)
(2) Plug-in Universal Checkback Module for
periodic testing of the carrier channel at
programmable intervals (see Chapter 17).
(See Figure 3–3 for connection diagrams.)
The equipment identification number (catalog
number) is located in the middle of the front panel
(just to the left of the 10W PA Module). The
TC–10B catalog number comprises eight (8) char-
acters, each in a specific position. This number
identifies the unit's technical characteristics and
capabilities, as well as any optional modules
installed in the unit.
Table 2-2 provides a complete listing of the
options for ordering a TC–10B, as well as a
sample catalog number. To order one or more
TC–10Bs, simply identify the features and
optional modules you want for each chassis. For
example, the typical catalog number shown in
Table 2-2 —
S 1 A 1 W V A S — orders a
TC–10B with the following features:
Basic TC–10B Transmitter/Receiver
Power Output: 10 watt
Universal Checkback: Universal Checkback
Module, PC programmable
dc/dc Converter Power Supply: 110/125Vdc
battery input
Bandwidth (Filter Range): Wideband filter
Voice Adapter: Voice Adapter Module with
signaling
Alarm and Carrier Level Indication: with loss-
of-dc-power alarm relay, R.F. output alarm
relay, received-carrier-level-margin alarm
relay, detect alarm, instrument indicating
carrier level (-20dB to +10dB), carrier level
analog output (0–100 µA) for external instru-
ment
Outputs: Dual transistor-switched outputs (for
use with electro-mechanical carrier auxiliary
relays and microprocessor relays)
Table 2-3 provides a further breakdown of the
TC–10B catalog number by style numbers.
The accessories available for the TC–10B are
listed, along with their style numbers, in Table 2-4
and Table 2-5. To order an accessory, simply give
its style number.
