Micro Filters and Splitters

Most ADSL clients will be required to install a simple device that prevents the ADSL line from interfering with regular telephone services. These devices are commonly referred to as micro filters or sometimes called (inaccurately) line splitters. They are easy to install and use standard telephone connectors and cable.

Some ADSL service providers will send a telecommunications technician to modify the telephone line, usually at the point where the telephone line enters the building. If a technician has divided or split your telephone line into two separate lines - one for regular telephone service and the other for ADSL – then you do not need to use any type of filter device. Follow the instructions given to you by your ADSL service provider about where and how you should connect the Router to the ADSL line.

Micro filters

Unless you are instructed to use a filter it will be necessary to install a micro filter (low pass filter) device for each telephone or telephone device (answering machines, Faxes etc.) that shares the line with the ADSL service. Micro filters are easy-to-install, in-line devices, which attach to the telephone cable between the telephone and wall jack. Micro filters that install behind the wall plate are also available. A typical in-line micro filter installation is shown in the diagram below.

Micro filter Installation

DO NOT install the micro filter between the Router and the telephone jack. Micro filters are only intended for use with regular telephones, Fax machines and other regular telephone devices.
