6.4.2.1 Definition
This service is used between MSC-B and MSC-A (E-interface) indicating that the radio path has been
established by MSC-B to the MS. MSC-A retains then the main control of the call until it clears.
The response is used by MSC-A to inform MSC-B that all resources for the call can be released in
MSC-B, either because the call has been released in MSC-A or because the call has been successfully
handed over from MSC-B to another MSC.
The MAP_SEND_END_SIGNAL service is a confirmed service using the primitives from table 6.4/2.
