Abstract
Apparatus and a concomitant method of providing a technique, within each central office (CO) in a digital CO cluster, for translating a destination number for a signaling message into a destination point code. Such a CO generally contains a switching system, for providing an interface to various station lines (telephone lines) and links to other DCOs, and/or an A-link consolidator (ALC), and an SS7 signaling processing system for providing a software based control system to properly format, address and route signaling messages. Through the invention, the SS7 signaling processing system first translates a destination number into a destination point code. The destination point code is then incorporated into a signaling message. The signaling message is subsequently routed to a destination node that corresponds to the destination point code. The destination point code indicates either a CO within the cluster or an STP outside of the cluster. Advantageously, use of the invention eliminates the need to translate the destination number into the destination point code without accessing an SS7 node outside of the CO cluster.
