Configure IMT
You configure the PortMaster 4 for Signaling System 7 (SS7) by setting the SS7 gateway address and TCP port, the TCP port on the PortMaster 4, and the switch type. You must configure each slot independently. The SS7 gateway address and target TCP port are provided by the SS7 gateway administrator. The TCP port of the PortMaster 4 is the base value that is used to generate the source TCP port number for the Quad T1 or Tri E1 board in each slot that has active intermachine trunks (IMTs). The actual port number is the base value plus the board's slot number.
To view and edit IMT, Click Boards in the control tree, select a Quad T1 board in the display, and click Edit. Then click IMT in the panel that appears.

Gateway |
SS7 gateway IP address in dotted decimal notation provided by the SS7 gateway administrator. |
|
Gateway Port |
SS7 gateway port is the TCP socket in the SS7 gateway that listens for SS7 clients. This socket is provided by the SS7 gateway administrator. |
|
Base Port |
Local TCP socket on slot 0 of the PortMaster 4, which is used to communicate with the SS7 gateway. When entering this value, use the same value for all slots on any single PortMaster 4. The PortMaster 4 also uses this as the base port on slot 0 and automatically increments this number by the slot number of the next slot connected to an IMT. |
|
Switch Type |
Default or 1a Enables the PortMaster 4 to interpret the loopback command from the SS7 gateway as a continuity check request either from a 1A switch or from all other switch types (default). Note - If you set the switch type to 1a, you must set signaling to robbed bit signaling (RBS) on the lines attached to the switch. |
