My nightmare installation..

continues to be totally flakey.

As of yesterday, all perfectly fine. New router, New filter..Today,
person comes into office, takes the DECT handsets off their charging
cradles (Siemens C475 duo) and bang. No ADSL.

Remove phone station lead from Netgear supplied filter. ADSL at
15Mbps+. Yippee..


She's not smart enough to try it all with the phones on the base
stations..but WTF is happening?

I could understand poor speeds, but not complete inability to connect.

Dodgy BT master socket? (only one on this line at all).

Any ideas?

I'm a bit stumped..

Remove DECT and get a known working phone (corded) or butt,
Test you can make calls out and get calls in without the DSL sync
dropping. Prove it's not just some random weirdness with the phone.
A good old lightning strike on the exchange can cause all kinds of
carnage to all items wired.

If your happy it is not the phone listen for crackling/noise - it may be
the only hint you get. I've known lines to be HR and drop like this when
the phone loops the line (the HR in effect giving out under current load)
but normally the line would be so bad you would notice it.

Finally run a BT line test on it via their website if you can, just to
check for any obvious rubbish like reccy loops, foreign battery or earth
conditions.

Good luck matey....

Disconnect and power off ALL the DECT phones. Get a vanilla handset £10
from Tesco) and plug it into the phone socket on the microfilter.

Can you make and receive calls with this phone? If there are failures,
EXACTLY when do they occur? Monitor the router - for example if the ADSL
drops when the phone goes off hook, but reconnects after the usual
negotiation delay; then drops later when the phone goes on hook; this is a
recognised symptom of a high resistance joint on the line. Alternatively if
the ADSL drops when the phone rings for an incoming call even though the
call is not answered.

If BT attend to investigate such a fault, be aware that they should try to
replicate it with their own hardware. You may have to supervise the
technician very closely to ensure that he does so correctly.

Beware that BT technicians very often can't find such faults within the
2-hour time slot allocated. It will pay you to get a professional ISP on
your side first !!!

I've had similar problems with a VOIP ATA which also connected to the BT
line as backup. They sell a multinational version where you need to set
a lot of the BT line parameters ike impedance etc, ( this was a liksys
SPA3102 ).

I'm not saying any of this applies to this particular phone. I only
mention it because they do a VOIP version of this phone the C475 IP.

I've had a look at my Siemens S685IP and it doesn't appear to have any
settings for the BT line. So I guess all I'm saying is that a dodgy
phone could do this the ADSL may be fine.

Ok..that's a possible explanation..the dect loads the lime somehow,
blowing the ADSL away, because of perhaps a dodgy joint?

Ah. That's worth a try..how does one do that?

OK. good stuff. There is a POTS there.. the dect only went in yesterady.
Oddly they had complained that it (POTS) worked but 'didnt ring' but
when I put teh new filter in, it rang fine. So did the dects. I assumed
the old filter had taken a surge and crapped out, now I am not so sure..

That should be OK (IDNET).

But there would seem to be more work to do... first

I thionk I'll have the faceplate off next and check for anything obvious.

The key you guys have provided is how a line load at DC.baseband could
screw up ADSL frequencies.
