Integrated services digital network (ISDN) and broadband integrated services digital network (B-ISDN) generic addressing and transport (GAT) protocol Study Group 11
This Recommendation provides the protocol for Generic Addressing and Transport (GAT). GAT is a
protocol for exchanging Application Protocol Data Units (APDUs) between service provision points
that may be located within the same network, between networks, or between a terminal and a
network. This Recommendation also provides a common framework for the use of ROSE or for the
support of other application dependent content (e.g. in the IN environment) and interpretation
capabilities in conjunction with the GAT protocol.
The protocol is applicable to the signalling network, and may be used in conjunction with the Digital
Subscriber Signalling System No. 1 (DSS1) protocol, Digital Subscriber Signalling System No. 2
(DSS2) protocol, Signalling System No. 7 (SS No. 7), and is applicable at interfaces where those
protocols are applicable.
The details of addressing and routing at the level of the transport mechanism are outside the scope of
this specification.
