ABSTRACT: GR-2997, ISDN BRI Trunk Generic Requirements, provides the call processing, access signaling, and operations requirements for the ISDN
BRI Trunk feature. ISDN BRI Trunk allows a collection of ISDN BRIs to be treated as a group for the purposes of originating and
terminating calls, and for provisioning capabilities and features. Call control procedures are based on GR-268, and include
modifications to provide the equivalent of Direct Inward Dialing and Direct Outward Dialing. In addition to support for call control
and operations, these requirements also provide the incremental requirements necessary to provide these BRI features on the BRI members
of the BRI Trunk group: Calling Number Identification Services, Calling Name, Call Forwarding Busy and Call Forwarding Don't Answer.
BRI Trunk specific operations requirements include provisioning, maintenance, surveillance, and billing. A new BRI Trunk group view is
used to simplify provisioning.
