Installing a Splitter and Micro-filter
2. INSTALLING A SPLITTER AND MICRO-FILTER
A splitter and micro-filter allow you to use your Router and telephone at the
same time. The splitter connects to the ADSL wall connection, and then pro-
vides two connectors:
• An RJ11 connector which connects to the Router with the RJ11 cable
• A telephone jack connector which can be connected to your telephone
There must also be a micro-filter between the splitter and the telephone. The
micro-filter ensures that DSL data signal does not interfere with the telephone
voice signal. A micro-filter must be installed inline with each telephone to
prevent signal interference. Splitters are now available with built in microfil-
ters, which simplifies the setup as shown in the diagram below. Splitters and
micro-filters can be obtained from your ISP or a computer store.
