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. ZyXEL provides a microfilter that
acts as a low-pass filter for your telephone to ensure that ADSL transmissions do not interfere with your
telephone voice transmissions.
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.
