     With more than one phone on a line, family members can unknowlingly pick
up extensions while you're using your modem, causing undesirable errors.  To
avoid this problem, you can make your computer phone, or modem, the priority
station.

     In most cases, the wire feeding your computer phone has four conductors,
but only the red and green are active.  Without disconnecting them from your
phone, wire these two through a double pole switch, and back to the two extra
conductors (usually yellow and black).  This will take the dial tone back
through the wires to the entrance bridge, the connecting block where the
phone wires enters the house.  At the bridge, remove all wires going to
telephones, except the two going to the computer phone.  Then hook the
disconnected wires to the yellow and black wires coming from your switch.  If
your extension phones won't break the dial tone after this is done, simply
reverse the yellow and black wires.

     Now you can use your switch to disconnect all extensions while you're
using your modem.
