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.
Broadcasting
By using ISDN and digital codecs (an analog to digital interface),
broadcasters can transmit music, news, or commentaries with
superior clarity.
Video surveillance
Dial-up access using videocodecs (an analog to digital interface)
provides advanced surveillance on demand.
