Well as of the 23rd of July 2008, Telcos announced the digital network roll-out, both Optus and Telstra have announced that they have commenced rolling out their digital networks that will see the end of PSTN switched networks on the copper infrastructure by replacing it with fibre to the node (FTTN) and voice over IP for telephony.
This will mean that Digital alarm dialers using DTMF may be effected from the 23/07/2008 onward. Considering 90% of all alarm panels out there rely on the copper network, why don't we start with Class 1.
I have already explained in another post why dialers will not work, and to refresh on that, it is purely because VoIP uses Codecs to transmit voice (digitising an analog signal) now when you have an already digital signal from an alarm panel and you Encode it to digital again, you will have some sort of loss in the compression the codec uses, and when it is Decoded you will get loss again.
The question now is, what has been done to accommodate these changes in the telecommunications infrastructure for the end-user to have a solution that keeps them in the same class as previously achievable over PSTN, without "Automatically" being upgraded to a Class 3 Transmission device?
