M2UA Signaling Extender (SX) Configuration

Simple SS7 Migration to IP

The Signaling Extender (SX) configuration provides an SS7 signaling extension capability by backhauling ISUP over M2UA (MTP2 User Adaptation Layer). The SX routes SS7 traffic over an IP network to an IP-enabled device, or routes IP traffic over an IP network to an SS7 device. M2UA backhauls provide transparent connectivity between traditional, circuit-switched SS7 signaling points and next generation, IP-enabled signaling elements. By leveraging MTP2 to M2UA interworking, the SX provides this functionality with no additional point codes and requires no modifications to the MTP3 addresses or routes on either side. The SX provides a method of communication for an MTP3 layer on an SS7 device to reach Media Gateway Controllers, as well as databases and other applications with peer MTP3 layers that run on IP-enabled devices.

Protocol Stack for M2UA backhaul

The SX utilizes M2UA to backhaul SS7 traffic over IP. M2UA provides an interface between MTP3 and SCTP that enables MTP3 applications to transparently operate over an underlying transport service of SCTP and IP instead of MTP2. This interface provides transparent connectivity between traditional circuit switched SS7 signaling points and next generation, IP-enabled signaling elements, such as a SoftSwitch or Media Gateway Controller.
