Hub 4 causes interference to landline.

For about 4 weeks now i've been having a intermitent problem with my broadband or phone. Whenever someone calls or if i call out, my broadband turns off and you get a flashing orange light. Also ive noticed that the call quality is low with static/buzzes/crackling noises, but when i turn the hub off at the switch the noises vanish. I've tried the master test socket and there in no noise on the line. As i said this is a intermitent problem, so when i phone bt they say that everything is fine with the line test. I baught a new faceplat/filter for my socket, replaced the rj11 cable, but the problem still exists. can it be a faulty hub?

I just checked the "bt wholesale speed tester" it says that my line has a ping latency of 30000 is that normal.

Re: Hub 4 causes interference to landline.

Hi,

 

it it might possibly be a HR (high resistance ) fault on the line. We had a similar problem a few years ago where we could hear the broadband signal when making telephone calls and the if we received or made a call the hub connection would drop out to the orange light and then reconnect. It was intermittent and would only appear during wet or misty weather. It was finally proved to a corroded connection where the drop wire was terminated at the pole. 

The problem we had was reporting it whilst the fault condition existed as once the weather improved and it was dry the fault would disappear.

Re: Hub 4 causes interference to landline.

how do you report a high resistance fault, the bt operator just does a line test and says everything is ok?

Phone 151 and report a phone fault

Re: Hub 4 causes interference to landline.

Have you eliminated any in house wiring that might cause the fault by connecting to the test socket of the master socket. I think the distinguished sages could explain how to do this before reporting a fault.

Re: Hub 4 causes interference to landline.

The test socket is the only one i have and the rj11 cable connects directly to the face plate. I have replaced the faceplate and cable, and even tried a corded phone. As i said before the problem is intermittent and random. The noise on the line only occurs when the hub is on, the moment i turn it off the noise disappears  also if i listen carefully i can hear the broadband signals with the noisy line.

What does your master phone socket look like?

Master socket with one socket

Or

Master socket with two sockets
