scope:

This Recommendation covers the requirements of equipment that interconnects GSTN networks at the TDM interface and networks optimized for the transport of IP (e.g., GSTN to IP gateway, vehicle gateway and integrated access devices). Such equipment is referred to in this Recommendation as a TIGIN gateway. This Recommendation describes functionality such as voiceband coding and echo control, transport interfaces, signalling interfaces, and OA&M interfaces of these devices. Support is provided for calls from IP to GSTN, GSTN to IP, IP to IP and GSTN to GSTN. While such TIGIN gateways may support multimedia traffic and remote access server (RAS) functionality, this Recommendation covers only voice, voiceband data, facsimile, narrow-band digital data, address and signalling tones. Support of other media such as digital data and video are outside the scope of this Recommendation.

This Recommendation describes bearer and signalling-related aspects of a TDM to IP interworking media gateway. It does not describe the requirements on a media gateway controller, with the exception that the MGC is required to provide ITU-T Q.115.1 echo control logic. This Recommendation does not define any new protocols or network architectures, but rather refers to existing protocols and architectures. It also does not specify a level of performance, as this will be covered by other Recommendations referenced by this Recommendation. Operation and management procedures are outside the scope of this Recommendation.

TIGIN gateways are assumed to support bulk interconnection between GSTN and IP networks. They are considered to be a trunking and not an access gateway. Support of asynchronous transfer mode (ATM) on the GSTN interface is not included in this Recommendation.
