Get ready for 21CN with DigiPlus®

DigiPlus® has been developed as a solution to the uncertainty surrounding BT’s Next Generation Network (NGN), the 21st Century Network (21CN). 21CN was scheduled to upgrade the whole UK PSTN network over the next five years. This strategy was recently changed to focus on upgrading exchanges as and when the new technology is required or the legacy equipment within the exchange has reached the end of its economic life.

Since the announcement that the 21CN roll-out will happen on a more spontaneous basis, Installers should be on the alert for Telephone exchange upgrades in their region. Failure to do so may result in existing signalling devices that rely on copper telephone lines, such as digital communicators susceptible to malfunction with the added cost caused by additional phone line charging from non-freefone numbers.

DigiPlus® is a small device that was developed in conjunction with Vodafone that fits between any existing digital communicator and the telephone line providing an improved and robust signalling solution. DigiPlus® is guaranteed to make all existing digital communicators fully compatible with BT’s 21CN. DigiPlus® will operate on both the old and new networks, providing the Installer with peace of mind that if the exchange is upgraded, the Alarm system will still signal through to the Alarm Receiving Centre.
