necessary to put several ISDN-PRI narrowband channels into one wideband channel to accommodate the needs of these applications. This feature supports both European and North American standards.

Multiple Subscriber Number (MSN) - Limited

The ISDN standard MSN feature lets customers assign multiple extension to a single BRI endpoint. The MSN feature works with BRI endpoints that allow the Channel ID IE to be encoded as “preferred.”

Automatic TEI (Termination Endpoint Identifier)

The user side will support automatic TEI assignment by the network. Both fixed and automatic TEI assignment will be supported on the network side.

ATM-CES Trunks

ATM-CES (Circuit-Emulation Service) lets the DEFINITY ECS emulate an ISDN-PRI trunk on an ATM facility.

ATM Trunks

Support telephony and Wide-Area Network (WAN) connectivity over ATM networks.

Personal Central Office Line (PCOL)

Provides a dedicated trunk circuit between multi-appearance voice terminals and a CO or other switch via the network.

ISDN Presentation Restriction

Replaces "Presentation Restricted" or "Unavailable" Calling/Connected number with an administered text for display. The administration options can be controlled on a per-ISDN-Trunk-Group basis.

ISDN Feature Plus

Enables those without DID to direct dial users on a remote PBX via the public network. ISDN Feature Plus eliminates the need for Attendant intervention for those without DID capabilities.
