How do I bypass the inside wiring of my home?

In some cases, it may be necessary to disconnect from the phone wiring of your home to
troubleshoot a problem. The simplest way to do this is to disconnect the phone cord from
the Telephone 1 jack on the back of the modem, and to plug one of your home phones
directly into that jack. This will significantly simplify the connection to allow us to find
where a problem may be.
