Serial Data Interface Ports - Avaya Nortel Communication Server 1000 Reference

NTDW56 and NTDW59 Common Processor Media Gateway card
If a fatal self test error occurs during bootup, an error code appears and the PASS and LOAD
messages do not display.
During normal operations the LED displays the IP Media Gateway (IPMG) superloop and MGS
shelf number. If an error occurs the display cycles between the shelf number and the error
code. Each item is displayed for 20 seconds.

Serial data interface ports

The two RJ45 serial ports (TTY1, TTY2) provide serial connections to the Common Processor.
The CP MG card serial ports are factory configured to 9600 bps 8-N-1. You require an
NTC325AAE6 CP MG serial port adapter kit, a customer provided straight through Cat-5
Ethernet cable, a 9 pin and a 25 pin serial cable, and a maintenance terminal to establish serial
connections. The NTC325AAE6 CP MG serial port adapter kit includes a 9 pin and a 25 pin
adapter. The 9 pin adapter provides TX, RX, and ground for null modem. The 25 pin adapter
provides a full set of signals without null modem for DCE. The CP MG serial port adapter kit
is required to connect to a 9 pin or 25 pin serial cable. The adapter kit pin mapping is shown
in Table 258: CP MG serial port adapter kit pin mapping

Ethernet connections
The CP MG card provides four external Ethernet LAN connections. Two connections are on
the faceplate, and two connections are on the backplane. Dual homing is supported on each
pair of LAN connections. The CP MG card does not support a High Speed Pipe (HSP)
connection.
