To install filters

You must install a filter on every telephone that uses the same telephone number as your DSL service.

Phone filters block out potential noise on your phone line and improve performance of the Internet connection.

  2. Plug the desktop filter cable in to the wall jack.
  3. Plug the telephone cable you unplugged from the wall jack into the jack on the filter.
  4. Repeat this process for every phone jack on the same line as your DSL service.
