scope:

This European Telecommunication Standard (ETS) specifies the B-ISDN meta-signalling protocol and procedures for the pan-European Broadband Integrated Services Digital Network (B-ISDN) as provided at the T_B reference point or coincident S_B or T_B reference points (as defined in ITU-T Recommendation I.413 [3]).

The meta-signalling protocol and procedures define the activity that is used to establish, maintain and release signalling virtual channels at the B-ISDN User-Network Interface (UNI). The meta-signalling protocol needs to be invoked by B-ISDN terminal equipment on a multiple access UNI so that it is possible for its signalling channels to be allocated by the network. Once the signalling channels have been allocated, the signalling protocol stack can be created and signalling can proceed.
