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.
