I've just moved this thread to where, IMHO is it's proper place.
necrosan asked a supplementary question about the number of microfilters required in a "thank you" post (http://www.solwiseforum.co.uk/showthread.php?s=&threadid=1365) that was originally in the "Solwise -> Solwise Feedback" section. I gave an answer to the question there and necrosan asked for more clarification. I thought that I should really answer the question over in this part of the forum. So here goes! :)
necrosan asked what happened if ADSL became active on the line but not all of the telephone sockets had microfilters plugged into them.
The answer!
Apparently BT's policy is that all of your sockets should have microfilters in them even if you aren't going to plug in a phone at all of them. This may have something to do with preventing an RF interference "leak" at unfiltered sockets but I'm not too sure. The story goes that if you have to get a BT engineer to call in to fix a fault then they will tell you off if you are short of some microfilters. This is the policy that Solwise has to follow of course, to prevent problems with BT.
Now I'm going to tell you what actually happens in practice. If you have a socket that you intend to leave unused then this will not effect the operation of the ADSL or the other phones in the house.
I just performed a test in my house, by plugging in a phone without using a microfilter. This is what happened. If the phone was left on-hook then both incoming and outgoing calls from the other phone (filtered) in the house were unaffected and both phones rung on incoming calls. ADSL operation wasn't effected either. However if I picked up the handset on the unfiltered phone then the ADSL modem lost line sync and the ADSL stopped operating. It was also impossible to hear a conversation over the "rushing noise" of the ADSL modem. The modem re-synced once the handset was replaced and ADSL operation was restored.
Hope that this helps.
Steve
