Connecting A Terminal - Nortel 1000M Installation And Commissioning Manual

Connecting a terminal

Terminal guidelines
Communication Server 1000M and Meridian 1
Connecting a system terminal or modem
During the system installation and for continuing system operation, a
terminal must be connected to an SDI port in a network slot to provide an
I/O interface to the active CPU in the system (for local access). In addition, a
data terminal equipment (DTE) port (COM1) and a data communication
equipment (DCE) port (COM2) on the Call Processor Pentium IV (CP PIV)
card can be used for direct access of the cPCI Core/Network Module.
Typically, the CP card ports (COM ports) or COM1 and COM2 are
pre-configured on I/O addresses four and five.
The COM1 and COM2 ports are active only when the CPU associated with
the CP card is active. Therefore, the COM1 and COM2 ports should not be
used as the only I/O connection for the system.
When the initial installation is complete, you must leave a terminal or a
modem connected to the system. One SDI port in a network slot must be
permanently connected to a terminal or modem. On the COM1 and COM2
ports you can:
1 disconnect the ports;
2 leave terminals connected for local monitoring; and,
3 connect modems for remote monitoring.
The ABCDE-Switch, which provides up to four-to-one switching, is
available from Nortel as part number A0377992. The switch box can be used
to connect the SDI and COM1 and COM2 ports to a terminal or a modem. If
used, one switch box must be used for terminals and one for modems.
Commercial terminal servers can also be used to concentrate the serial ports
on the equipment in a telecom room.
During an installation, you can connect terminals to the COM1 ports for split
mode monitoring, or programming, or both. (Due to the speed of the system
messages displayed, personal computers are useful for file capture and
review.)
