Hi,

Since about Friday, I have had a horrible, loud, scratching noise on the phone line that makes it nearly impossible to hear people. At this point the internet was running fine.

I did isolation tests with different filters, phones and jack points, and concurred that the filters and phones were fine, but one of the jack points in the house was causing this issue. I have 2 jackpoints, the 1 in the lounge has the ADSL modem, and the one in the kitchen has a filter and cordless phone.

When any phones were plugged in with filter into the kitchen jack point, I had the horrible noise. In most cases only I can hear the noise and not the caller, but the caller can hear me absolutely fine.

When I unplugged the modem and plugged in a phone with filter into the lounge jackpoint, the phone calls were fine.

I would plug both phone and modem into the one jackpoint, but I don't have a double adapter.

Now as of last night, my internet speed has been dropping, to where it is now. (normally around 2.4Mb/s)













What would be causing all of this? Is it my internal wiring (house is about 3 or 4 years old), or is it the line to the house somewhere, or is it VF?

Any help would be great!

I had something similar, turned out to be a faulty jack/wiring. Usually the twisted pair terminate on a primary jack. Open this jack and disconnect downstream jacks (ie pull the wires out) and see if things improve. In my case I assmed that something may have chewwed on my internal wiring and have left the other jacks disconnected.

The wiring is all in parallel so it's not as if you are disconnected from the kitchen just because you are plugging into the lounge. Your tests seem to have some holes. When you had good phone calls was the modem plugged in the kitchen? Have you tried the phone in the kitchen with the modem disconnected?

Don't your filters themselves have double adapters in that there's a modem socket and a phone socket?

Yes I tried the kitchen phone with modem disconnected. The filters are cheap DSE ones that only have the single phone output. Modem is plugged directly to a phone plug.

At the moment I have a long roll-up extension phone cable plugged into the lounge jack, with the phone (with filter) plugged into one port on the extension, and the modem straight into the other port on the extension. Not ideal by any means, but I don't have a crackly phone and the speeds are around 1Mb/s which is manageable.
