SS7 TCAP User Adaptation Layer (TUA)

This document defines a protocol for the transport of any SS7 TCAP-User signalling (e.g, INAP, MAP, etc.) over IP using the Stream Control Transport Protocol. [RFC 2960] The protocol should be modular and symmetric, to allow it to work in diverse architectures, such as a Signalling Gateway and IP Signalling End-point architecture. Protocol elements are added to allow seamless operation between peers in the SS7 and IP domains.
