METHOD AND APPARATUS FOR INTEGRATED SERVICES DIGITAL NETWORKUSER PART (ISUP) SIGNALING LOOPBACK

摘要

A method and apparatus are provided for processing Integrated Services Digital Network User Part (ISUP) signaling within a switching system. ISUP signaling messages associated with a plurality of ISL trunks are processed within a switch ing system by provisioning the ISL trunks, identifying the ISUP signaling messages t hat are associated with the ISL trunks, and routing the identified ISUP signaling me ssages within the switching system to the far endpoints of the trunks using layers 1, 2 , and 3 of Open System Interconnection (OSI) protocol.
