ADSL & VDSL Filters
High quality ADSL & VDSL filters. Required for the connection of telephones & any other analogue equipment such as fax machines to ADSL/VDSL broad band lines. The filter splits the high frequency DSL signal from the lower frequency voice band allowing both services to use a single copper pair! If you fail to use a filter a telephone (or any other analogue device) will interfere with the DSL signal causing drop outs whenever the phone is taken "off hook".
