Signaling System 7 Message Transfer Part 3 - User Adaptation Layer

Overview

RFC 4666, “Signaling System 7 Message Transfer Part 3 - User Adaptation Layer”, is a Proposed Standard document published in September 2006 by K. Morneault, J. Pastor-Balbas. It obsoletes RFC 3332. The canonical text is published by the RFC Editor.

Abstract

This memo defines a protocol for supporting the transport of any SS7 MTP3-User signalling (e.g., ISUP and SCCP messages) over IP using the services of the Stream Control Transmission Protocol. Also, provision is made for protocol elements that enable a seamless operation of the MTP3-User peers in the SS7 and IP domains. This protocol would be used between a Signalling Gateway (SG) and a Media Gateway Controller (MGC) or IP-resident Database, or between two IP-based applications. It is assumed that the SG receives SS7 signalling over a standard SS7 interface using the SS7 Message Transfer Part (MTP) to provide transport. This document obsoletes RFC 3332. [STANDARDS-TRACK]

What “Proposed Standard” means

An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
