Phone Line Sharing - Definition

Phone Line Sharing - A technology that allows a single phone line to share incoming and outgoing access for multiple devices. Typically Phone Line Sharing Technology allows voice (phones and answering machine) and a fax machine or fax modem to operate on a shared phone line. Other applications include any variation of voice, a fax machine, fax/modem and/or modem(s).

Incoming calls are automatically routed to the proper device(s). If the call comes in and it is a fax call, the call is automatically routed to the fax machine or fax modem. If the call is a modem call, it is routed to the correct modem. Voice calls are routes to phone(s) and/or answering machine. May require a security access code (SAC) in the dialing string to automatically switch to the modem. All outgoing calls access the line from any device. Optional "barge-in protection" protects any voice or data call from being accessed by other telephone equipment on the same line.

Since the need for to subscribe to a separate "fax line" or "modem line" from the local telephone company is eliminated, the return on investment (ROI) is very high. The initial cost of the device is returned in savings in a few months. After that you will save the monthly bills associated with fax, data or voice lines. For almost every business, phone line sharing technology is a smart investment.
