Product Characteristics and Packaging :
When using a DSL connection with a telephone or fax machine, it's
necessary to put a filter on the line to separate the signals for
the modem (higher-frequency ADSL) from the signals for the phone
and fax (lower-frequency POTS). This filter/splitter has three RJ11
jacks to do just that. Connect the 'line' jack to your wall outlet
cable, and connect the 'phone' and 'modem' jacks to your phone or
fax line, and to the modem. Each jack is conveniently labeled.
Signal quality is preserved and your connections stay clear of
static and noise from interference.
