Group 4 Fax; Remote Lan Access; Leased Line Backup; Lan To Lan Bridging - Nortel Modular ICS 4.0 Manual

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
incurred only when information is actually transmitted.

Internet and database access

The fast call set up and high bandwidth of ISDN are ideal for
accessing information services such as the Internet and
databases.
