Line type and installation

What type of line do i need?

Single Analogue

A standard line that is primarily used for making voice calls,
connecting to fax machines and to receive broadband.

Multi Line Analogue
Having an additional line allows you to receive a call. Should a call come
through to an engaged line, the call will simply be passed to the next
available line using the same number.


A single high-quality digital line that has two 64k channels, each used as a separate line for voice, data, video or fax. You can add further ISDN2e circuits to your installation, increasing the number of simultaneous connections and/or available data bandwidth.

ISDN lines allow you to have separate phone numbers allocated to your users either via devices connected directly to the circuit or through a PBX phone system.


Used by larger organizations, ISDN30 lines support between 8 and 30 digital channels and provide all of the features of ISDN2e.
