to
resolve this and am totally stumped as to the problem. Diagnosis as
follows-

-This connection is a straight A/B connection form the BT linebox
oustide the house, there are NO extensions, just the master socket

-Have replaced the microfilter with a new one and now with the high
quality XF1 filtered face plate: still get the line noise and bad
upstream

-If I disconnect the ADSL modem (3Com office connect) the line
noise
stops

Does this not sound like the HR (high resistance) fault that was
recently discussed here?

Hopefully kráftéé will be along to add his comments.

Sorry just got back from a boozy weekend, have I missed anything???

To the OP, the 3Com Office Connect routers suffered from a bout of
faulty power supplies causing a problem with the routers (discussed at
great depth in the forum a month or 2 ago), when you are checking
without any synch is the router connected & powered up?.

Builders..... don't trust them, has some work done earlier this year,
pointed out the cables to be avoided at all costs only to find they
had put a nail thru the tele leadin & an extension (not bad for one
nail) & also crushed yet another one for good measure , when patched
got a 50hertz hum, caused by the new electrical cables being run close
by so I had to reroute.

As for the HR connections, been meeting up with them a lot (possibly
due to the damp/muggy weather). All _you_ can do is check & double
check all connections, have the builders crushed the cable (or hit it
with a nail etc) but after cheking your own internal
wiring/connections the only thing you are left with is reporting it to
your service provider, not BT, that way you should get an ADSL
'trained' engineer who may know (or not as the case may be) how to
check out the circuit/copper path back to the exchange. Report it as
a intermitent synch problem & hopefully everything will come up
smelling of roses, or chocolates depending on what takes your fancy..
