ISDN30/30e further information
BT ISDN
Lines
A single high-quality ISDN30/30e connection has between eight and thirty 64k channels. In normal operation you use these separately. This allows simultaneous calls over each channel.
You can add further connections to your installation, increasing the number of simultaneous calls and/or available data bandwidth.
A choice of delivery and diversion options helps to keep your business running in the event of a local technical failure.

Services
BT offers a range of digital services for ISDN30/30e which provide advanced call-handling features.
ISDN applications
You can use ISDN for voice calls and for high-quality data links with other ISDN subscribers. Digital connections are often used for transferring large files securely, for video-conferencing and for linking Local Area Networks at different sites.
You can make data calls to other countries that have ISDN services.
Internet
If ADSL is not yet available in your area, you can connect to the Internet at 64kbps using one ISDN channel, or at 128kbps using two channels together. Since each channel is a true 64k connection, you will find that even one channel performs significantly better than a 56k dialup connection. (For an analogue dialup modem, 56k denotes the maximum speed possible, not the average connection speed).
