Describes the extensions required for the support of the Generic Addressing and Transport protocol (GAT) mechanism over the public Network Nodal Interface (NNI). This application makes use of the Application Transport Mechanism (APM) described in ITU-T Q.765 (2000) for bearer related signalling, and the Transaction Capability (TC) for signalling involving no bearer.
