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 [RFC2960]. 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.
