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.
