Defining MSC links

If an XRF IMS system communicates with another IMS system over MSC links, you can change the priority with which IMS establishes new sessions on these links.

The BACKUP keyword in the MSPLINK definition controls the automatic recovery of MSC physical links and sets the priority for the establishment of new sessions on these physical links at takeover. Consider raising the priority that IMS uses to establish new sessions across these links. The default is BACKUP=4.

You can use the BACKUP keyword in the MSLINK definition to override the BACKUP option you specified on the MSPLINK definition for the logical link definition. The default is BACKUP=4.

Physical links can be defined dynamically. The specification of BACKUP in the definition of a logical link overrides any switching options that are specified in the definition of the associated physical link.
