I had Sky Fibre Unlimited installed last week and all is going well - getting really good speeds. I also have an ADT home alarm which is monitored via telephone line (it calls back to an ARC). The installation went fine, except that the BTO engineer didn't connect up the ADT alarm telephone line to the master socket. I got ADT out and they got it fixed no problem.
Yesterday, I got a call from the Sky Fibre Team to tell me that they have to roll me back to standard ADSL because my alarm system is not compatible with their fibre network due to "the frequency being too close and pulses on the line may degrade the system". But when I called ADT to ask them if this was the case, they said this was rubbish as it just works off normal telephone voice signal - I got them to test the line and they confirmed all was fine.
The thing is, I've called Sky a few times to try and sort this out and I cannot get a consistent answer from Sky about this - their safe route is "nothing is compatible", but I also have had the "we don't know" answer. ADT are adamant that there should not be any problem and that they have installed alarms in many premises that have got FTTC.
Anyone with experience/suggestions/advice greatly appreciated - I don't want to go back to a crummy 3Mb/s line when it is currently a whizzy 37Mb/s!
Sky Fibre Unlimited (at the mo) 40Mb/s!
