Connecting Serial Ports
The Intuity system communicates with various devices through serial ports. Serial
ports are required for:
■ MERLIN LEGEND administration
■ Optional Remote Maintenance Modem
■ Optional Call Accounting System
■ Optional customer administration terminal(s)
Only MERLIN LEGEND administration and the Remote Maintenance Modem are
constrained to specific ports. Any other connections are made to available ports.
There are two built-in ports on the Intuity system processors. If three or more
devices are required, a Multi-Port Serial Card must be included in the
configuration.
■ Built-in Serial Port 1 (COM1, tty00) is used for administering the MERLIN
LEGEND system.
■ Built-in Serial Port 2 (COM2, tty01) is used for the second device. If the
Remote Maintenance Modem is present, it must be connected to this port.
The numbers in circles are the
punch-down connector positions.
