should be installed at each home telephone.

Unplug the telephone from the wall. Plug the telephone cord into the end of the
EZ-DSL microfilter marked PHONE.

Using the 3-inch telephone cord provided, plug one end of the cord into the
microfilter marked WALL. Plug the other end of the cord into the telephone wall
receptacle.
Step 4
After you have finished installation, verify that your telephone service works. If
your telephone service does not work, disconnect the EZ-DSL Microfilter and
contact your local telephone company or Cisco Systems.
