infernalsiren Posted June 27, 2014 Share Posted June 27, 2014 I would like advice on the following issue. Customer had mentioned that broadband drops at random times but always came back. He has fibre and has the openreach vdsl filter plate fitted. I noticed that his A?T galaxy monitored alarm is spliced into the phone line in the loft where the line comes in, this line then continues to his master line box with vdsl plate. There are no other phone sockets fitted or in use. Could the alarm even if it has an Excelsus filter in it cause interference? Thanks Quote Link to comment Share on other sites More sharing options...
AlarmScot Posted June 27, 2014 Share Posted June 27, 2014 The only way to fix that is to get Openreach out to fix it and it may cost him a small fortune. He could get a Local Phone Engineer out to look at it as many of them are ex-Openreach Lads. Quote Link to comment Share on other sites More sharing options...
datadiffusion Posted June 27, 2014 Share Posted June 27, 2014 (edited) Shouldn't be 2 filters on one line. Needs to be connected in series with the filtered output from the VDSL plate and rest of telephones. Only thing connected to the unfiltered line should be the DSL modem.

datadiffusion Posted June 27, 2014 Share Posted June 27, 2014 Not saying it wouldn't work, see it all the time, but I thought it would load the line up with parallel inductance?

Paul P Posted June 28, 2014 Share Posted June 28, 2014 If it was redcare clasic I don't think it needs to be filtered. The old adsl did not but i am a bit rusty on fibre. Quote Trade Member Link to comment Share on other sites More sharing options...
