I have a dpdt relay in front of my Zoom Modem. Normally closed points
connect line 1 to zoom. When line 2 rings the relay energizes for ten
seconds and line 2 is connected to zoom. I use Alpha card to drive relay
and homemade ring detector connected to Alpha Input card.
This gives me ability to monitor CID info on both lines.
