Routing messages through MSC to an ISC LTERM

You can route messages across an MSC link to an ISC half session.

Suppose you have a setup similar that shown in the following figure. IMS A and IMS B connected by an MSC link. SYS C is connected to IMS B with an ISC link. If you want to route input messages and output replies between IMS A and SYS C, place the ISC routing parameters in the IMS prefix portion of the message. The MSC link-processing preserves these routing parameters.

Begin figure description: Input Message flows from Terminal 1 to IMS A, then across MSC link to IMS B, then across ISC link to SYS C, and finally to Terminal 2. End description.
