How do I Install an Old-Style Wall-Mount DSL Filter for BellSouth

The filter is labeled Excelsus Z-Blocker and has a locking panel below the faceplate. There is a filtered jack on the front and an unfiltered ADSL jack on the bottom.

To filter a telephone or other device with an old-style wall-mount filter, do the following:

1. When there is a phone on the wall jack, do the following:
   • When there is a phone on the wall-mount jack that uses a locking lever, pull the lever out to unlock the phone from the jack.
     • NOTE: Locking levers are usually located on the right side of the phone, at the base.
   • Push the phone up and gently pull it away from the wall.
   • When the phone is connected to the jack using a short telephone cord, disconnect the cord from the jack.
2. Locate the PRESS TO LOCK tab on the filter. Gently pull the tab outward as far as it will go.
3. Place the filter over the wall jack. Line up the filter's plug and mounting slots with the jack's port and mounting pegs.
   • NOTE: The plug on the back of the filter can slide up and down to help with alignment.
4. Push the filter into place.
5. Push the PRESS TO LOCK tab inward.
6. When reconnecting a phone to the wall jack, do the following:
   • When the phone must be connected to the jack using a short telephone cord, connect the cord to the unfiltered jack on the front of the filter.
   • Place the phone over the filter. Line up the phone's plug and mounting slots with the filter's port and mounting pegs.
   • Push the phone inward and down until it is secure.
   • When the phone uses a locking lever, push the lever inward to lock the phone to the jack.
     • NOTE: Locking levers are usually located on the right side of the phone, at the base.
7. When connecting an ADSL modem to the same jack as a telephone or other device, plug the modem into the ADSL phone jack on the bottom of the filter.
