MTP3 User Adaptation
MTP3 User Adaptation (M3UA) provides transport for ISUP/SCCP messages over an IP infrastructure. M3UA extends the reach of the SS7 network into the IP network. The signaling gateway running M3UA is addressable in the SS7 network. The signaling point is a fully distributed entity, with processing in both the SS7 and the IP network.
