Frequent Disconnects, Out of ideas!

Hi all, i could really go for some suggestions right now.

Heres the scenario, For the past couple of months my connection keeps dropping whenever the phone rings in the house. I have been with zen for over 12 months and different isp's before that and have never had a problem till now.

I started a thread about this a while back and thought that the problem had been resolved, but sadly not.

The virtual paths at the BT exchange are currently at 'RED' status. Nothing has changed in the house, no new phones, no new phones lines etc...

Things I have tried:

New Microfilters throughout.
Disconnected all phones and connected just one standard one at the master socket.
Tried using a second different ADSL modem router.
Contacted BT to check the line, they report no fault found.
Disconnected the 'bell' wire from the socket which my modem is connected to eliminate the possibility of noise.

Are there any checks that can be done at Zen's end? Its driving me nuts because the connection is unreliable.

Any suggestions appreciated.

The common causes of this are faulty or incorrectly installed filters, or a fault with the internal wiring. You appear to have eliminated every possible cause at your own end; you've replaced the filters with new ones, you've tried a different ADSL router and you've disconnected your internal wiring and tested from the master socket.

The only other possible explanation would be that there is a line fault somewhere, though tracing this may be difficult. BT will have tested the line and found no fault but they most likely are simply testing to see if the line is working (which it is) not to see if some condition existst that would make the ADSL drop when a call takes place.

The only other thing I could suggest is posting this in the Technical Issues forum to see if any of the BT guys that lurk there have any ideas.

Thanks, will re-post in the technical forum.

Probably best to link to this thread rather than start a new one, so that you're not seen to be cross-posting.

Couple of other things to try. Have a search through the Technical forum for similar problems, there may already have been a solution posted. You could also browse through the forums on the DSL Zone UK site.

Have you plugged your router directly into the master socket? You only mention plugging a standard phone in there.

Helping my brother in law the other day he didn't get his ADSL working until he removed the cover from the master socket and plugged directly into the socket behind without a filter He's now fitted an NTE5 filtered faceplate. It's important to remove the possiblity of a fault in any internal wiring still being connected even if nothing is connected to it.

You say this only happens when the phone rings, all that I know is when the phone rings the voltage on the phone line is increased to something like 75V ac I think, could be something going wrong with the incoming voltage.

I guess you've tried it with no phones on the line could be a faulty phone or perhaps someones put a faulty bug on your phone line somewhere.
