More about ISDN2e

ISDN2e has the ability to link multiple connections together – each with its own connection box (NTE), but with DDI numbers across all linked connections.

The use of DDI numbers is exactly the same as with ISDN30e.  ISDN2e can also be used with stand alone equipment such as Video Conferencing, although this is now usually done via an IP (Internet Protocol) connection.


To switch your BT lines to Spitfire, or to discuss installing new ISDN2e lines for your office, please just give us a call on 0800 319 6363.
