ISDN2e - Digital System

A basic single ISDN2e line has two 64k channels. In normal operation you use these separately, so you can make or take two calls at once.

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 and also video-conferencing and linking Local Area Networks at different sites.

You can increase the number of channels in multiples of 2 up to a maximum of 60 (although if you are going above 8 channels we would recommend using ISDN30e lines instead).

The following Calling Features are available on ISDN2e Digital System Lines:

Call Deflection - Deflect incoming call to another number without answering it;
CLI Presentation (CLIP) - View the telephone number of an incoming call.
CLI Restriction (CLIR) - Withhold your telephone number when making telephone calls.
Customer Controlled Call Forwarding - divert incoming calls to an alternative number when engaged, unanswered or for all calls.
Direct Dialling In (DDI) - Have multiple numbers using one line, seperate numbers for each member of staff.
Incoming Call Barring - Bar all incoming calls leaving all lines available for making outbound calls.
Outbound Call Barring - Bar the ability to dial different types of calls.
Sub Addressing - Dial directly into a device on your network.
