line drops when a telephone is connected. Please Why?

Hi
I have a 2mb connection. It seems to work fine but when I plug a telephone
into the line my connection is dropped. I have tried all the usual things to
stop this from happening including changing the phone, plugging into another
socket, changing the filters, trying without filters, taking sky off the
line but nothing seems to change. As soon as I plug a telephone back into
the line (at any point on the extension in the house) my broadband
connection is dropped and I am then unable to connect again until all the
telephones have been disconected again.
Has anyone come across this before and do you have have thoughts about what
might be the problem and how can I cure it? I have had BT out to check the
lines and they have not found any problems.
Regards,
Lenny

Sounds like a bit of scientific diagnosis is required.

Have you got an NTE5 master socket with removeable faceplate? Is all your
extension wiring connected into the back of the faceplate? If the answer is
Yes to both questions, do the following.

1. Take out the 2 screws and remove the faceplate, letting it hang loose on
the extension wiring.

2. Plug the BB modem or router directly into the test socket behind the
faceplate. [You'll need a BT to RJ11 cable for this - maybe the one from
your old analog modem]. Check that the BB works.

3. Plug a filter/splitter into the test socket and connect your BB modem
into the ADSL outlet socket of the splitter (using the standard RJ11 to RJ11
cable). Check that the BB still works.

4. Now plug a phone into the phone outlet of the filter/splitter. Check that
the BB still works when the phone is both on hook and off hook.

If it *doesn't* work in the test socket, there is something wrong either
with the line or with the filter. Try some other filters and/or get BT to
fix the line.

If it *does* work - but won't work in any other socket (with the master
faceplace re-installed, of course!), it suggests a problem with your
extension wiring. Other than replacing it all, your best bet would be to use
a filtered faceflate - which will isolate your extension wiring from your
ADSL connection at source - and connect your BB kit into the ADSL outlet of
the filtered faceplate, running a digital extension to the required
location, if appropriate. [If you *are* running a digital extension, it's
best to use a modified faceplate such as the one from Clarity
http://www.clarity.it/telecoms/adsl_faceplate_mod.htm which allows you to
wire into the back for neatness].

thanks tim I will take a look and give it a go. Because we are quite a way
into the country (Lincolnshire) but only about 5K from the exchange, could
it also be that the broadband at 2mb is to much for the line. Would it make
any diffence to get the service dropped down to 1mb or even 512?
Cheers
Lenny

get some line stats and we might have a clue.

lower speeds are always more stable, but your problem sounds to be a
dodgy phone or wrong filtering.

Possibly - but it shouldn't have been installed at 2M if your line doesn't
meet the criteria.

Does your modem or router provide any line stats (when it's working!) -
particularly Downstream Attenuation and Noise Margin (or SNR)? If so, what
are the figures?

Thanks Tim and Phil,
I am using a modem from tiscali and will get the line stats in the morning
and post them here asap. (problem at another property)

have a look at www.samknows.com

put your details in and it should advise if 2mb is supported where you are

Great link! At last got some figures for my Belkin router.

Thanks,

Sounds like what the BT people call an HR dis, i.e. high-resistance
disconnection, because there is a poor joint somewhere that causes the
voltage drop across the line to increase too much. This often affects
ADSL. Make sure it isn't in your wiring (if you have an NTE5 remove the
cover and try direct into the test socket revealed, removing all
extensions etc) and then ring 151 and ask for more investigation.

Hi Brian,
We have had BT out to the line and they have checked all the connections
between the property and the exchange. There is a clicking sound on the line
that sounds like an electic fence but BT are unable to work out where this
is coming from and I think they have now given up on the problem. We also
have Redcare on the line but they and BT say that it shouldn't cause any
problems.
