ISDN (Integrated Services Digital Network) is a facility provided by BT whereby a company can have many lines linked to the same phone number. Usually linked to a PABX switchboard, this allows the incoming calls to be directed to the extension of their choice.

BTN provides the full range of ISDN connectivity, usually at rates below those charged by BT. Coupled with our low cost Call Minute charging plans, we have customers who enjoy savings in the range of 25% to 40% over their previous suppliers.
