It's my mother's line. The fault is either the voice side either going
open-circuit, or short circuit. On outgoing calls, it causes
'cleardown'. On incoming calls there's a click and loss of audio for a
few 100 milliseconds, and all carries on again as normal.
On Friday night, the line was permanently 'engaged' for at least 4
hours, at mother's end no dial tone, just a 'humming sound' so perhaps
it's a short ?
You should probably have reported it whilst it was in this state.
Intermittent faults are a problem to track down by their nature.
The broadband router logs don't report any traumas, and an 'uptime' of
40 days, speed unaffected (16ish meg sync speed ADSL2+), and all the
happy lights remain green and normal (even during the 4 hour 'engaged'

Therefore I'm fairly confident the problem is somewhere inside the
Not necessarily it could be a line break in the making that is still
capacitively coupling the ADSL sync RF but is unable to carry the
current required to maintain a POTS circuit.
Checked master socket, extensions, etc, etc.
Unfortunately, it's a very intermittent fault (except for Friday's session)
Anybody ever experienced similar ?
Not exactly the same. Bad lines usually take down ADSL too. Do the error
second and CRC error correction on the modem show anything unusual?
