ITU-T Q.704 (07/1996)

Signalling network functions and messages
This Recommendation describes the functions and procedures for and relating to the transfer of messages between the signalling points, which are the nodes of the signalling network. It has been modified to allow use by the broadband ISDN User Part in the narrow-band environment, and the Satellite ISDN User Part.
