O2 Landline – Choosing the right landline

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.

ISDN2e

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.

ISDN30

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

Landline is available throughout the UK (within BT's licence area which excludes Kingston upon Hull, Isle of Man, Isles of Scilly and Channel Islands)
