ISDN terminals and services
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 Modular ICS allows connection of 8 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.
Your installer configures your ISDN services and terminal 
equipment.

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.
