ISDN BRI terminals
Your Compact ICS supports up to eight Basic Rate Access loops (four
2B+D channels) that can be used for fully digital connections to ISDN
networks and devices. Loops are connections between the ICS and devices
or between the ICS and the network.
Each loop provides two separate B-channels that can be used to make two
simultaneous voice or data calls, or one data call and one voice call.
ISDN applications
ISDN terminal equipment delivers a wide range of powerful business
applications:
• Videoconferencing and video telephony: Videoconferencing offers
instant visual and audio contact between distant parties using either
studio-based or desktop ISDN terminals.
• Desktop conferencing: ISDN allows computer users in distant
locations to share and edit any image, data or text file on their own
computer screens while they discuss the information.
• File transfer: The ISDN network allows you to transfer files
containing data, text, images, data, or audio clips, faster and cheaper
than with a conventional modem.
• Telecommuting: Convenient retrieval, processing and storage of files
is possible for the employee working at home by using ISDN lines to
give high-speed access to information resources at the office.
• Group 4 fax: ISDN fax applications save money by increasing both
transmission speed and the quality of resolution.
• Remote LAN access: ISDN provides an affordable and fast means for
employees at remote sites (at home or branch offices) to access local
area networks (LANs).
• Leased line backup: Essential backup for leased lines can be
provided using ISDN as required, rather than duplicating costly
permanent leased lines.
• LAN to LAN bridging: Local area network (LAN) bridge/routers
allow flexible interconnection between LANs using ISDN, with
charges only incurred when information is actually transmitted.
