Abstract
In a multiservices digital network (FIG. 1), comprising separate narrowband switch (607) and wideband switches (505, 606), the network control complex (612) includes a program-controlled call processing arrangement (800) that is program-independent of a resource management arrangement (803) and of the physical network. The call processing arrangement views the network as comprising logical channels and logical call paths interconnecting logical channels. It does not distinguish between narrowband and wideband communications; it responds to subscriber (102) messages requesting subscriber functions for both narrowband and wideband communications by directing the resource management arrangement to establish and dismantle logical call paths and to create and destroy logical and physical connections between the logical channels and the logical call paths. The resource management arrangement distinguishes between narrowband and wideband communications; it responds to the directions by allocating and deallocating either narrowband or wideband network physical resources, as appropriate, for physical channels and physical call paths corresponding to the logical channels and the logical call paths, and directs either wideband switch controllers (507, 610) or narrowband switch controller (611), as appropriate, in creating and destroying the requested logical and physical connections between the channel and call path resources. The call processing arrangement is thus made independent of network physical resources, while the resource management arrangement is made independent of subscriber functions.
