<p>The principle object of the present invention, is to provide flexibility in the routing functions performed in the switching system. Another object is to provide a router (200) that can be centralized in a host computer (24) or distributed among various switching nodes (32b-32f). The router is easily programmable by the system operator to provide different routing algorithms for various calls. The router can be used in a system with a single switching node. However, it is particularly adopted for use in a multiple-switching-node system, either as a central, host resident unit, or as a distributed router resident on the switching nodes. A router embodying the invention uses router tables (201) that are readily configurable by the system operator to route calls based on predefined routing criterion in the incoming or outgoing call.</p> |
