The Belkin ADSL in-line filter/splitter maximises the performance of your ADSL (Asynchronous Digital Subscriber Line) service. It allows you to connect an ADSL modem and telephone device to the same ADSL port. It creates clearer voice communications and prevents interference by separating high frequency ADSL transmissions from phone signals. The filter isolates low-frequency voice signals to ensure the cleanest network performance with fast, error-free data transfers.
Belkin recommends that an in-line filter be used on each available phone socket in your house that has a device connected to it such as a telephone, fax machine, caller ID system, answer machines and digital pay TV.
