Hello,

I'm about to connect an ADSL modem to my phone line, but I have an old,
pulse-dialling wall phone in another room, which I assume will interfere
with the modem, so it has to be disconnected or a filter attached. I
took the cover off and the cable has four wires, two pink and two
yellow, attached to a board, each with a quick-connect connector. They
aren't easy to get at, so I want to know what the minimum required is to
disconnect it. That is, how many of the wires and how do I determine
which ones? I have a volt meter.

Wall phone with no plug?

Two of the wires are used to talk to the exchange, the other two were
used to mute the bells in other phones on the premesis during pulse
dialing

I think it's blue and white that need the filter. it's the two that if you
disconnect either of them the dial-tone goes away.

Yeah. Annoying. Other than side cutters, all I can do is hope the
quick-connects aren't so tight I'll break something pulling them off.

Great. Thanks.

I connected the ADSL modem for the first time last night with the wall
phone still connected. It worked, but it was slow (about 5 mbps
download). It was just as slow today at 4 am. I know I'll have to
disconnect or filter the wall phone if I want to use the line as a phone
line while the internet is on, but I don't know if it's having any
effect when it's on-hook.

Without the filter, most likely when it goes off-hook it will disrupt
the internet connection until the ADSL modem sorts out the changed
line parameters. same when it goes back on hook. during pulse dialing
nothing will work.


Best fix may be to fit a whole-house filter and run a line from
before the filter to serve the adsl modem.

in -----+---- filter ------ phones, alarms, fax machines etc.
|
`-- adsl modem

Basically the filter goes somewhere bear the start of the where the
pne wires come into your house your existing wirng serves your
existing phones. and you install a new branch for the modem.

If there's a branch from the first fork in the wiring that goes
directly there already you just need to connect that branch before the
filter - so long as the wires in that branch are good.

All the ADSL filters I've used take care of this internally:

/-- phones etc.
in ---- filter ---+
\-- ADSL modem

I think that would require getting a technician in. For the moment I'll
use the filter (for the main phone) that was included with the modem.
Thanks for your help.

I disconnected the wall phone. It wasn't too difficult to pull off the
connectors. My speed went from ~5 mbps to ~6 mbps, but there's a lot of
variability repeating the test so maybe it didn't make any difference.
