This report examines the functional requirements for a broadband V interface in conjunction with the previously defined V5 and ISDN protocols in order to define a usefule set of protocol component parts. At this stage, the report shall not attempt to define a unique protocol stack for a new version of a Vb interface (which would support narrowband, broadband and asymmetric services through ANs). New protocols may be identified if required.
