Port Assignments

The communications system assigns logical IDs and extensions to each port on the MERLIN Messaging System module. The first logical ID and extension assigned to the MERLIN Messaging System module is assigned to Port 1, the second to Port 2, etc. The communications system assigns 12 logical IDs and extensions to the MERLIN Messaging System module.

In Release 2 or later, if a Message-Waiting Light (MWL) update or Outcalling action needs to be performed, the following ports are used:

In Release 2, the Remote Maintenance Device (RMD) is not assigned to a dedicated logical ID and extension. For system configurations using 10 or less licensed ports, the RMD can be alternatively accessed on the twelfth port.

The following table defines the Port Assignments for the MERLIN Messaging System Release 2 or later.
