<p>A system and a method for disconnecting a communication device (214) from a communication line (222) thereby freeing the communication line for other communications such as emergency communications are disclosed. A signal detector (210) monitors the communication line for the presence of a predefined signal. Upon detecting the predefined signal, the signal detector causes a switch (224) or relay to disconnect the communication device (214) from the communication line (222). A remote device is utilized for detecting a predefined condition at a strategic location. Upon the remote device detecting the predefined condition, either via direct detection or via actuation by an operator, a transmitter in the remote device transmits a signal to a receiver coupled to the switch, thereby disconnecting the communication device from the communications line. When the invention disconnects the communication device, the communication line is free for other communications.</p> |
