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 that can be centralized in a host computer or distributed among various switching nodes. 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 that are readily configurable by the system operator to route calls based on predefined routing criterion in the incoming or outgoing call. |
