Parameter Specification
T1 connector (rear panel.) RJ48
PC control interface:
Two types of connectors. (RS232 with RJ11 on
the front and RJ45 Ethernet on the rear of the
ICB)
RJ11 (RS232) craft interface (directly connect PC on front
panel)
Default: data rate 9600, 8 data bit, 1 stop bit, No parity.
RJ45 network management interface (10/100 Base-T,
Full/Half Duplex Ethernet for connection into an Ethernet
network.)
The network management PC interface can control and
monitor functionality for both local and remote environ-
ments.
T1 monitor bantam jacks (On front panel only) This is to monitor the primary T1 signal (monitor transmit
and monitor receive) without interference.
Alarm interface and contacts The alarm contact connector is a 4-lead connector rated for
1 amp. One set of isolated contacts each for the audible
and visual alarms per PUB-43801. A typical connection is
expected to be 18 or 22 gauge wire.
The system provides visual and audible alarm contact clo-
sure when the channel bank is in alarm or there is a loss of
power. When the ACO (Audible Alarm Cut Off) is activated,
the audible alarm contacts return to open circuit.
Composite clock termination (jumper selectable,
rear panel)
IN—135 Ohm termination on composite clock input.
OUT—No termination on composite clock input.
ACO switch (front panel) Use to silence the audible alarm contacts

OCU, CSU, DSU non-latching loopback for 56 KB/s and
subrates
V.54 loopback code for 56/64KxN
Voice port test pattern generator and detector
(software selectable on a per-channel basis)
