Table 1-4 IDCSU Connector Ports
Port Located Usage
Modular Front The modular connector on the front of the TAC 2130 module is not used. To
configure an IDCSU, connect to the controller module.
Bantam Jacks Front The bantam jacks are present only on the TAC 2130. They will never reflect
actual signals on the T1 circuit. Do not use these bantam jacks.
Network Rear Connect the T1 line to this port.
Data Rear Connect the supplied adapter cable, which in turn connects to the customer
data equipment. The DTE must support the synchronous serial interface type
for which the selected CDM is designed.
Management
Port In
Rear Some of the rear connector modules have management ports which are not
used when the front module is a TAC 2130 or TAC 2130-S.
Management
Extension
Rear Some of the rear connector modules have management ports which are not
used when the front module is a TAC 2130 or TAC 2130-S.
Ext Timing Rear External timing is supported in the TAC 2130, not in the TAC 2130-S or TAC
2130-T. Connect an optional external clock source, using either a TTL level (0
to +5V) or balanced (RS-422) signal. The clock must be at 1.544 Mbit/s.
Alarm Relay Rear Connect an external alarm system which triggers on either a relay closure
(using NO and COM leads) or open (using NC and COM leads). The relay in the
IDCSU module supports Form C relay specifications.
