NBN Phone Systems Will my Alarm System work? Probably not reliably.

Will my Alarm System work?
Probably not reliably. Security systems often use a traditional telephone line to
monitor by sending a small amount of data what is effectively an old dialup modem
(remember those?) and sending it over a telephone line.
The big change when moving across to the NBN is that there are no real telephone
lines, they are just imitated using VoIP which isn’t perfect for Alarm Systems. When
these same sound signals are carried by the VoIP, there is the occasional loss of
data leading to small gaps in the sound.
I can’t tell you how many times I’ve heard the sad story of a security system failing to
report a break and enter because the line was not connected or working correctly.
A noisy alarm system without a telephone line to report is near
useless.
Don’t get caught out here.
Just like EFTPOS terminals Alarm systems have several different methods of
reporting and not all security companies offer all services. You may need to replace
your alarm system and or switch monitoring companies. You see the NBN has
limitations to provide the good old-fashioned telephone line for the necessary
security system to be of any real use.
The repercussions of assuming everything will be OK for the
security system could be catastrophic.
