  • A single high-quality ISDN2e line has two 64k channels. In normal operation you use these separately, so you can make two calls at once
  • You can add further ISDN2e circuits to your installation, increasing the number of simultaneous connections and/or available data bandwidth
  • If you wish, you can have an unlimited number of DDI numbers that can be allocated to phones or other equipment.
  • 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, video-conferencing and linking Local Area Networks at different sites
  • You can make data calls to other countries that have ISDN services
NTE8 Front
ISDN2e lines are a great way of consolidating your telephone lines and reducing overall line rental for a site

  • 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 both 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)
