Unlikely that the FAX has been damaged as ringing on a normal line can put
upto 90V ac on the line.

Depending on length of line from the exchange, the line would also limit
the
current that could flow so there should be enough to do any damage.

If the machine has been damaged by something as trivial as that then there
is no way it will survive through thunder storms !!!

Did he use the machine on the analogue ports of the HH before conversion ?

It could also be down to the quality of the line.

I only live 5 minutes walk from the exchange but when I had two analogue
lines my modem would only manage 33k on one line and 41k (I think...its a
long time ago) on the other. I had home highway installed and discovered
that my old analogue modem would connect at 50k on the alalogue ports
presumabley because the line was digital all the way to the house and was
better quality. For conversion to ADSL I had to have HH removed two months
before the exchange was ready and dropping back to a shared modem running
at
33k was horrible after the luxury of 64K ISDN. No that I have 8Mb ADSL I
dont want to go back to any form of dial up ....EVER :)
