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. Connect another cable from the double jack end of the Y-Connector to the Prestige.
Connect the "phone side" of the microfilter to your telephone as shown in the following figure.
