Help troubleshoot adsl sync/line problem

I had adsl enabled on a line here about a week ago and it had been working
fine until recently..

However, it now sometimes loses sync with the exchange - can anyone suggest
any reasons why?

When it was installed (last sunday) I spoke to the BT engineer and he said
that it was well within spec for the service (its a 2MB line)

Until friday it was working perfectly, then on friday evening it lost sync
with the exchange for a short while (15/20 minutes I think), it did this
again on Saturday morning and on Sunday afternoon.

I have both an Alcatel USB modem and a Speedtouch Home (hacked to Pro) here
and the problem appears to apply to both of these.

The only difference at my end is that until Friday morning I was plugging in
the rj11 cable in via a fax/modem adaptor (totally unfiltered). On Friday
afternoon I changed this to a BT ADSL faceplate (as sold by
http://www.clarity.it/) - could it be a faulty faceplate?

I am online now via the same faceplate so if it is that the issue it would
be intermittent?

Also, each time after I have lost sync I have tried removing the faceplate
and connecting the rj11 cable via the fax/modem adaptor - providing an
unfiltered signal again but the modem/router doesnt want to know until the
exchange is ready again.

Therefore it sounds to me that something is affecting the line card at the
exchange and I have to keep on waiting until it automatically resets itself
(ideas?)

The Speedtouch Home/Pro doesn't produce anything worthwhile in logging terms
and the USB modem reports zero CRC/SDU errors but it does report loss os
signal/framing/errored seconds everytime this happens.

Finally, when using the BT ADSL faceplate I have a CallSign switch (model:
telcom 650) plugged in to the "voice port" - though I woudn't have thought
that would cause any problems to the adsl part of the line..

Do I need to get my ISP to get BT to look at the line card or could it
possibly be down to the filter?

TIA for any help/advice

Hi,
given that everything was fine until the new faceplate was installed, I
would suspect a dodgy connection or faulty faceplate. I had a problem like
this with a phone a while back, and eventually tracked it down to a damaged
wire from when I did the wiring. When I had removed the insulation, I must
have damaged the wire. To look at it, you'd never be able to tell, but the
conductor had broken inside the insulation an inch or so from the end. I
was surprised that it worked at all when I realised, but the two halves of
the conductor must have been touching inside the insulation most of the
time.

I can't comment on the callsign switch, as I have never used one. But I
would be surprised if that was the problem.

I`ve got a router and mine still loses sync occasionally (sometimes
several times a day) but it also stays up for 10 days at a time.

If its not down to the exchange, it could be down to the filter as its the
main thing which has changed at my end - but in my case it was simply
unsrewing the old NTE5 and putting the new one in iits place - no extensions
etc to wire.

Does anyone know how frequently these BT ADSL faceplates are found to be
faulty?

Out of interest, which router is that?

I am using the Alcatel USB modem and/or the Speedtouch Home - both pieces of
kit that BT used to issue to end users - so it should have been extensively
tested before hand..

In addition, this "loss of sync" seems to last for 15/20 minutes at a time -
its not just dropping the connection and allowing me to reconnect
immediately - this making me thing that something is affecting the line card
@ the exchange (until the card is reset automatically?)
