M2UA: MTP2-User Adaptation layer
MTP2-User Adaptation layer (M2UA), a protocol in the SIGTRAN protocol suite, is for backhauling of SS7 MTP2-User signaling messages over IP using Stream Control Transmission Protocol (SCTP). M2UA is intended to be used on a Provider/User basis where MTP Level 2 resides on a Signalling Gateway (SG) and MTP Level 3 resides on an Application Server (AS). It is not intended for peer-to-peer operation: that is, it is not intended to emulate a signalling link between two SCTP endpoints.
