phones and extensions not work with adsl

My neighbour has installed ADSL
When the extensions in the house are connected - his ADSL won't work
Also when ADSL in use he can't use his phone

Does anyone know why this might be and what he can do?

regards

Ian

-----------------------
Does he have micro filters on all phone sockets? if not this is the problem,
if he does then it may be that one of them is not working as it should in
which case if you are on ADSL try one of yours and see if this solves it if
it does then he needs to get a new one to replace the bad one.

Thanks for your reply

Unfortunately I am not on ADSL yet...

Would the lack of a filter on extension lines cause the ADSL itself to not
sync and connect though?

It shouldn't have any effect on ADSL. The output of a filter unit that is
labelled "ADSL" is actually connected straight through, so as far as your
ADSL equipment is concerned the device is only acting as an adaptor.

What is the exact setup?
How many extension points are ther and how many of these have phones?
Does he have individual filters on all extension sockets or one main
filter on the BT master socket?
Hve you checked wiring throughout, there could be a crossed pair
somewhere.

This isn't correct.
Using a device on the same unfiltered line as the ADSL modem can
certainly cause loss of sync.

You have confused the issue here. Providing there is no analogue
equiment connected to the line, irespective of the number of
extensions connected, there is absolutely no need for a filter.

Even when an analogue device is added to the line, a filter is ONLY
required for that device. So the ADSL modem can be connected directly
to the line on the extension socket, Period.

I know its bloody confusing but the adapter should really be called an
analogue filter for use on ADSL lines, then we would all know what it
is about.

Yes and no.
True, I may have misinterpreted the original poster. I made an
assumption that there was something connected on the end of the
extension line. Especially as the OP said the phone wouldn't work with
the ADSL on. I may however have got it wrong.

The 'no' bit refers to a posting I made a few weeks ago when my ADSL
line refused to work without a filter being connected - even if it was
the only thing in circuit.
I know what you are going to say, and a month ago I'd have agreed with
you.
Do a google.

I guess _you_ might have confused the issue here. The OPs scenario might
be a normal splitter (t-piece), one branch going to the ADSL modem and a
microfilter (or not) on the end, the other branch going off somewhere,
and a normal telephone connected without a filter. Which won't work
properly. Period.

I think we need to nail this one on the head. Please have a look at
the wiring diagram for a typical filter that is shown at the bottom of
the page of: http://www.adslnation.com/support/filters.php where we
can clearly see that the ADSL 'service' is straight through. There is
nothing on the analogue leg that would affect or enhance the ADSL
signal especially if there was no analogue equipment connected. So
what is a search with Google going to achieve? In your particular
case where you inserted a filter in the line to your ADSL modem
suggests to me that a good electrical connection was not being made in
the first instance and through 'disturbing' the connection one was
achieved. In can be nothing more than that.

Understand and agree with your conclusion for the set up as described
in this paragraph.

A search on google for my previous posting would achieve the result of
not having to repeat the whole thing here.

You are making a definitive statement based on nothing more than an
assumption that 'suggests' something to you.

In the light of you not knowing the facts, it would be unwise to jump to
such erroneous conclusions.

And just because the ADSL connection of a microfilter is 'straight
through' does not mean that the LCR components connected in parallel
will have no effect on the signal.
A rather extreme analogy would be to say that in a car, a piece of
equipment plugged into the cigarette lighter that is 'straight through'
to the battery will not be affected by anything else such as turning the
starter motor over.......
