How do the wireless phone jacks work?
One of the supplied boxes gets plugged into your wall outlet for power, and also plugs into an available RJ-11 phone jack (where you would have typically plugged in your phone). This box also contains a second RJ-11 phone jack port to plug a phone/fax/computer, or whatever existing device you may have already had using that port, back in. This is similar to an answering machine or a modem, it’s just a passthrough port. The second box gets plugged into the wall outlet for power, and contains a single RJ-11 phone jack port which you can use anywhere in the house. This is the port you would plug your satellite receiver into. The way this is made possible is the first box, which has a direct connection to you houses phone line, transmits that signal wirelessly to the receiving box. From there you directly connect your phone or satellite receiver with a cable. Cordless phones work in much the same way, the base has the connection to the phone line, and it transmits the signal to the wireles
