|Publication Date:||1 December 1999|
Scope, Purpose, and Application
The Intermediate Network Selection (INS) network capability
allows an application process in the origination network to specify
a single intermediate signalling network for non-circuit-associat
The INS capability may be invoked by a variety of services and network capabilities. The end user can interact with an end-user service that may invoke the INS capability. The specific enduser service that invokes INS is not within the scope of this capability description. Therefore, the INS capability is not visible to the end user, but allows an end-user service to take place. Thus, there is a "layering" of services and capabilities, and the visible end-user services may need the INS capability to complete.
