DEVICE FOR EXTENDING SIGNALING END POINTS AND SIGNALING ROUTES IN FULL ELECTRONIC EXCHANGE

摘要

PURPOSE: A device for extending SEPs(Signaling End Points) and signaling routes in a full electronic exchange is provided to accommodate SEPs up to 512, and to support 4 signaling routes for each SEP. CONSTITUTION: An ISUP(ISDN(Integrated Service Digital Network) User Part)(10) provides an interface with an ISDN subscriber or a trunk line. A memory(30) is built in an ASP(Access Switching Processor)_7, installed in an ASS(Access Switching Subsystem) processes NO.7 signals to control the No.7 signal processing. Also the memory(30) stores information on SEPs of a remote station and information on available signaling routes and alternate signals. An SMHP(Signal Message Handling Processor)(20) acquires information on the SEPs of the remote station and signaling routes for processing originated signals from the memory(30), if an ISUP message for call connection is transmitted from the ISUP(10), to transmits the ISUP message to the SEP of the remote station through corresponding signaling routes. And an ST(40) provides a link function between the SMHP(20) and the remote station.
