Nortel Networks 6.1 manual Isdn

ISDN

Integrated Services Digital Network (ISDN) technology provides a fast, accurate and reliable means of sending and receiving data, image text and voice information through the telephone system.

By using Basic Rate Interface (BRI), your ISDN service allows for faster transmission speeds and the addition of a variety of powerful business applications, including remote LAN access, videoconferencing, file transfer and Internet access.

Your installer configures your ISDN services and terminal equipment.

ISDN BRI

Compact ICS supports the following ISDN services:

•incoming calls

•outgoing calls

•Calling Line Identification Presentation (CLID)

•Sub-addressing

•bearer capabilities

•teleservices

The Call Forward All Calls feature can be used from ISDN terminals connected to Compact Plus.

Note: Norstar and Business Series Terminals (BST) telephones can accept voice calls only. Video and data calls do not alert at the telephones.

Although an ISDN S-loop or LT-loop can support up to eight devices, the loop has a limit of two B-channels. If both B-channels are in use, other devices on that loop cannot make or receive calls until a B-channel is available, or until both B-channels are available in the case of a video terminal. Thus, the number of terminals installed must take into account whether you require dedicated access for the terminals on that loop.
