By Command Communications
The CS 5500 is a state-of-the-art Telephone Line Sharing device which eliminates the extra dedicated telephone lines used to operate a fax, modem, or other telephone device. The CS 5500 quickly directs incoming telephone calls to one of four appropriate destinations, typically a computer modem or fax/modem and facsimile machine, as well as a telephone and answering machine, or any other telephone device that responds to a standard phone company ring signal.
