Upstream fault


[link to this post]
 
Bt engineers visit, mention possible hr fault as can hear router on line. But don't fix it :no:
Downstream Upstream
Line Coding(Trellis): On On
SNR Margin (0.1 dB): 22 70
Attenuation (0.1 dB): 635 315
Output Power (0.1 dBm): 161 124
Attainable Rate (Kbps): 2240 256

Path 0 Path 1
Downstream Upstream Downstream Upstream
Rate (Kbps): 2048 160 0 0

Also when there is the rustling/buzzing the line has resynced, and sometimes resyncs whilst on line. Also what is causing the clicking, which is intermittent, but is there most of the time.

Hr faults pick up all manner of noise. Like an old am radio that would work better after a good thump due that fixing a loose joint for a while

Would that also cause the clicking?

The rhythmic clicking in this link I have had personal experience of, resembles the clicking that the old style telephones made when the number you called was ringing out , you heard the ringing tones closely followed by the clicking , It maybe some kind of bleed through from the exchange ,but i have heard the same on a line that showed no other audible signs of a fault, if you are able to heard your modem/router obtaining a sync whilst in a call, there is most probably a hr dis type fault somewhere ,

It's a fairly new bt phone with caller display, the clicking is there, whilst ringing but also during the call, could it be faulty exchange equipment, althought the rustling sounds external. It also seems to happen after a few phone calls, and its be raining for a while, but then stops.

Bad joint and possibily nothing to do with your phone

Bad joints will pick up noise from almost anything.

But wouldn't the clicking be a sign that it is in the exchange, to do with line cards, or am I talking rubbish?

Maybe but the days of relays and switched contacts are gone from exchanges, all digital now. So click click could be anything, needs test gear on the line to check things out

What test gear would find the root of the fault?, i think they use the jdsu but finds no fault?

If the standard kit finds nothing then might need an SFI to find source of interference and that can be as simple as an AM radio e.g. http://www.youtube.com/watch?v=OiFXjiG5OX0
