The present document specifies the procedures for establishing, maintaining and clearing of bearer connections to pointto-
point multiconnection calls at the B-ISDN user-network interface.
It specifies the essential features, procedures, and messages required for controlling bearer connections associated to
point-to-point multiconnection calls in a functionally separated call and bearer control environment.
The procedures specified by the present document are applicable at the interface between a B-ISDN terminal equipment
and a B-ISDN public network (coincident Sb and Tb reference point) as well as at the interface between a B-ISDN
customer network and a B-ISDN public network (i.e. at the Tb reference point).
The separated bearer control protocol defined by the present document is applicable to control bearers associated to a
multiconnection call which is controlled independently by means of a separate call control protocol.
