Broadband Integrated Services Digital Network (B-ISDN) and Broadband Private Integrated Services Network (B-PISN); Digital Subscriber Signalling System No. two (DSS2), Broadband Inter-Exchange Signalling (B-QSIG), and Signalling System No. 7 (SS7); Prenegotiation; Part 1: Protocol specification

Scope

The present document specifies the signalling protocol for the purpose of prenegotiation at the QB,SB,TB and co-incident SB/TB reference points within, between and at the access to Broadband Private Integrated Services Networks and within, between and at the access to public European Broadband Integrated Services Digital Networks. The protocol operates between two adjacent call control entities. The protocol is applicable in a separated call and bearer (connection) control environment for the support of calls having none, one or multiple bearers. The protocol is applicable to a two-party call or a multi-party call. However, prenegotiation is performed between two parties. In case of multi-party connections (point-to-multipoint connections), prenegotiation may be performed between the root and the first party.
