Micro-filters
Since ADSL and telephone services share the same copper wire to carry their respective
signals, a filtering mechanism must be used to avoid mutual interference. You will need
to install a micro-filter (low pass filter) device for each telephone that shares the line
with the ADSL line.
Micro-filters are easy to install in-line devices which attach to the
telephone cable between the telephone and wall jack. Your telephone company or ISP
will have more information regarding the use and installation of micro-filters.
VPI and VCI Numbers
You will need to know 2 numbers, the VPI and the VCI numbers, for configuration of
the Modem. Your telephone company or ISP will give you these numbers.
