SS7 MTP Level 2 User Adaptation Layer (M2UA)

This Internet Draft defines a protocol for backhauling of SS7 MTP2 User signalling messages over IP using the Stream Control Transmission Protocol (SCTP). This protocol would be used between a Signalling Gateway (SG) and Media Gateway Controller (MGC). It is assumed that the SG receives SS7 signalling over a standard SS7 interface using the SS7 Message Transfer Part (MTP) to provide transport. The Signalling Gateway would act as a Signalling Link Terminal.

This Internet-Draft provides information for the Internet community on the implementation of test cases for testing the SS7 MTP2-User Adaptation Layer [M2UA] Signalling Gateway (SG) based on the conformance test specifications for SS7 MTP Level 2 [Q.780..M2PATEST04].

This document presents the test specification for M2UA (MTP2 User Adaptation) prototcol (ver 03), which can be used to test M2UA implementations for conformance to the protocol definition. The list of test is exhaustive and covers almost all the categories of test. This draft can also be used in conjunction with M2UA specification by implementor of protocol as implementors guide, as the pictorial representation of various scenarios help easy understanding of the protocol.
