TM resources: MSNAMEs
MSC networks use MSNAMEs to define remote IMS systems and logical link paths between remote and local IMS systems in an MSC network. For MSNAMEs, Resource Manager (RM) enforces only resource type consistency for message destinations, but not resource name uniqueness.
When IMS initializes, IMS defines to RM each MSNAME that has a remote SYSID. Because resource name uniqueness is not enforced, the same MSNAMEs can be defined on multiple IMS systems.
Creation and deletion of the MSNAME TM resource
An MSNAME becomes a TM resource to RM at IMS initialization. RM saves the MSNAME in the resource structure. MSNAMEs are not deleted from a resource structure once they are defined and cannot be reused unless the resource structure itself is deleted.
