Broadband ADSL2+ Modem DM111PSPv2 ADSL Microfilters If this is the first time you have cabled a wireless modem between a DSL phone line and your computer or laptop, you might not be familiar with ADSL microfilters. If you are, you can skip this section and proceed to Cable Your Broadband ADSL2+ Modem to a Computer on page 11. An ADSL microfilter is a small in-line device that filters DSL interference out of standard phone equipment that shares the same line with your DSL service. Every telephone device that connects to a telephone line that provides DSL service needs an ADSL microfilter to filter out the DSL interference. Example devices are telephones, fax machines, answering machines, and caller ID displays. Note that not every phone line in your home necessarily carries DSL service. That depends on the DSL service setup in your home. Note: Often the ADSL microfilter is included in the box with the modem. If you purchased the broadband ADSL2+ modem in a country where a microfilter is not included, you have to acquire the ADSL microfilter separately. One-Line ADSL Microfilter Plug the ADSL microfilter into the wall outlet and plug your phone equipment into the jack labeled Phone. The modem plugs directly into a separate DSL line. Plugging the wireless modem modem into the phone jack blocks the Internet connection. If you do not have a separate DSL line for the modem, the best thing to do is to use an ADSL microfilter with a built-in splitter (see the next paragraph). Plugs into DSL line Figure 4. One-line ADSL microfilter Second best when you do not have a separate DSL line for the modem is to get a separate splitter. To use a one-line filter with a separate splitter, insert the splitter into the phone outlet, connect the one-line filter to the splitter, and connect the phone to the filter. Two-Line ADSL Microfilter Use an ADSL microfilter with a built-in splitter when there is a single wall outlet that provides connectivity for both the broadband ADSL2+ modem and your telephone equipment.
