Verilink NCC 2130 (880-503285-001) Product Manual - Manual (Page 14)

Overview
1-6 Verilink NCC 2130 User Manual
Port Usage Table 1-3 describes the usage of the ports on the various rear
connector modules (CDMs) used with the NCC 2130 front module.
Table 1-3 NCC 2020 Connector Ports
Adapter Cables Because of the limited space on the rear connector modules, a mini
D-Sub 26-pin connector is used for the data port connection in all
cases. A short adapter cable is also provided. This adapter cable,
sometimes called a pigtail cable, presents the typical connector for
the specific electrical interface. See
Table 1-4 for a cross reference
of these adapter cables.
Table 1-4 Adapter Cables Used With NCC 2130
Port Located Usage
Craft Front Connect ASCII terminal for configuration, diagnostics, alarm monitoring,
and/or performance monitoring.
Bantam Jacks Front The bantam jacks on the NCC 2130 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 Connect directly to a node management PC or to a modem for dialup to a PC
running either of the Verilink management programs — Access Manager 2000
or Node Manager.
Management
Extension
Rear Connect a cable to an additional node at the same location. This feature is
only supported when Access Manager 2000 is used for node management.
Ext Timing Rear 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 will trigger on either a relay closure
(using NO and COM leads) or open (using NC and COM leads). The relay in the
NCC module supports Form C relay specifications.
