2.4.2 Telephone Microfilters
Telephone voice transmissions take place in the lower frequency range, 0 - 4KHz, while ADSL
transmissions take place in the higher bandwidth range, above 4KHz. A microfilter acts as a low-pass filter,
for your telephone, to ensure that ADSL transmissions do not interfere with your telephone voice
transmissions. The purchase of a telephone microfilter is optional.
Step 1.
Connect a phone cable from the wall jack to the single jack end of the Y- Connector.
Step 2. Connect a cable from the double jack end of the Y-Connector to the “wall side” of the
microfilter.
Step 3.
