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

Note: Do not install the microfilter between the Router and the telephone jack.
Microfilters are only intended for use with regular telephones, Fax machines and other
regular telephone devices.
