Enabling MSC in an IMS system

Multiple Systems Coupling can be enabled in an IMS system either by coding the MSC=Y execution parameter in your startup procedure or, unless MSC=N is specified, by defining at least one MSC link during IMS system definition.

Recommendation: To ease operations when dynamic MSC is enabled and MSC resources are no longer defined using the system definition process, specify the MSC=Y execution parameter, even if MSC resources are defined with the system definition process.
