Technical Summary This document provides an IP-based surrogate for MTP2, a link-layer protocol used in SS7 networks, in order to enable IP-based telephony signaling points t use MTP3 over IP networks in the same fashion that they use MTP3 over MTP2 in SS7 networks. The MTP2 User Peer-to-Peer Adaption Layer (M2PA) runs over SCTP, and relies on SCTP assocations to simulate SS7 links. This protocol would be used by signaling gateways that interwork between SS7 and IP networks, or possibly native IP replications of SS7 endpoints. Working Group Summary The SIGTRAN working group supported the advancement of the document, and provided significant inputs in the final stages of its development. Protocol Quality This specification was reviewed for the IESG by Jon Peterson.
