All Phone lines must be filtered for the best DSL
service. First plug your DSL two port filter into
your wall jack. Be sure to plug the phone side of
your filter into your phone and the computer
screen side of the filter (DSL/HPN) into your DSL
modem. If you need additional filters for your sat-
ellite receiver or other phones, please order from
the front office (530-467-6000 or 1-866-467-
6001).
