A couple of months back I had a problem where my modem could not hold the line
open.  I had to leave a phone off hook with the secrecy button pressed in to get
the modem to work.  The electronics side of the modem was fine but the relay
which takes the modem off-hook had failed so the exchange did not register that
the modem had picked up (because it hadn't) so no dialtone.  Got a replacment
relay for a quid or so, ten minutes with a soldering iron and I was back on
line. HTH
