Protect yourself from NGN/21CN Issues with DigiPLUS

A Potential Problem
You may be aware that the telephone network in the UK is being upgraded from analogue switched circuit (PSTN) to digital Internet Protocol (IP) technology. The new networks are known as “Next Generation Networks” (NGN), the largest of these being BT’s “21st Century Network” or 21CN as it has become known. Next Generation Networks can cause problems with DigiCom and we are already experiencing this on a small number of systems. We expect this to become far more frequent in the future as telephone equipment is upgraded. It is not just your local telephone exchange that matters, it is anywhere on the network between the origin (your system) and the destination (the Alarm Receiving Centre). The effect of the problem is that your DigiCom unit may make multiple calls to the ARC each time it sends a signal, which may result in a dramatic increase in your call costs, often by ten times or more.

The solution

I am pleased to say that we have a solution to this called “DigiPLUS”. With DigiPLUS in place all calls from your system to the ARC will be free of charge and will not appear on your telephone bill, regardless of how many signals are sent. There is an additional ongoing cost for, but this is offset by the savings in call costs. Please contact us for details enquiries@abfands.co.uk. If we fit the DigiPLUS as part of your next routine service visit, we will be pleased to do this free-of-charge. We appreciate that the DigiPLUS may not provide much of a saving, however, it will protect you from the possibility of a “nasty surprise” telephone bill so we strongly recommend it to you.

RedCARE and DualCOM
If your system signals via RedCARE or DualCOM, the signals do not incur call charges anyway, so the above does not apply.
