About Line filters

Devices such as fax machines, caller ID boxes, or telephones that connect to a high-speed Internet line require a line filter, which separates voice and data and prevents noise from disrupting the high-speed Internet signal on the phone line. Filters must be added to every device that connects to a high-speed Internet line except for the high-speed modem. If you do not have enough high-speed Internet filters for your household, you can purchase more by visiting our online store.
