Low Pass Filters for DSL
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 microfilters or low pass filters. The two basic styles of
low pass filters commonly used are described below.
In-Line Filter
In line low pass filters are used for each telephone or telephone device (answering machines, Faxes etc.) that shares the
line with the ADSL service. These devices are attached to the telephone cable between the telephone and wall jack.
Filters that install behind the wall plate hidden from view are also available. A typical in-line filter installation is shown
in the diagram below.
