ABSTRACT:
A switch path reservation arrangement where any paths that are established for calls between two switching modules are reserved such that most future calls between the two modules are set up promptly using previously reserved paths with a minimum of inter-module message communication. Relatively few calls require a path hunt involving inter-module negotiation to determine a new path. Such new path is not only assigned for the call but also thereafter reserved for calls between the two modules. Path reservations are changed only when required to avoid blocking a call. Thus, the path reservation arrangement adjusts the number of paths between modules on a per-call basis to dynamically match the call traffic load.
