Abstract

   This document defines a protocol for the backhauling of Signaling
   System 7 Message Transfer Part 2 (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.
