using a modem on a ADSL line...

Having major problems getting any of my analogue modems working on my
recently converted ADSL line. They are all on the filtered (voice) side
of the filter, but none of them can detect a dial tone. I have tried 2
modems, both of which I am sure work, and also replaced the filter with
a X1-FE (supposed to be the dogs nads). Still cannot detect a dial
tone. Even if I disable "wait for dial tone before dialing", I t tries
to dial, but fails...

Anyone else had this problem?

(PS. I have noticed my SNR has risen significantly since swapping my
cheapo filter with the X1-FE, which is something good I suppose - up to
45 from 35)...

no :-)

I take it there is dial tone on the voice socket ? Try putting a 2 way
splitter on the voice port and listening in to the modem when you
blind dial - can you hear it ? If not you may have accidentally
swopped to a modem lead with the wrong wiring.

Another test would be to turn off the ADSL and try it without a
microfilter in the circuit.

Dunno anything about the filters you're using, but my first thought is that
the filter/splitter isn't compatible with UK lines. A lot of modem cables,
eg with the "small" plug on each end, are wired for US systems and use a
different pair of wires from here - you haven't added in any adapters to
convert plug types have you? I had a similar problem when I tried to be
clever about using a US sourced filter with my existing cables...

Are you using individual filters on every socket, or just have the main BT
socket filtered and other extns fed from this filtered socket?

Try a different telephone socket and see if that makes any difference, check
for dial tone with a telephone as well, as has been suggested already. I
have broadband and the cheap white filters made by Excelcius Technology
Model Z-420UK-A. These work and I can plug in my labtop which uses a pcmcia
33k modem and works from any filter no problem.


What software are you using to measure the SNR with (out of interest).
