ABSTRACT:
An information processing system adapted for use in conjunction with a telephone communication system. The information processing system includes a caller identification signal receiver, a timed switching device, and a call forwarding device. When no incoming call is being received, the timed switching device is in a first, open state, such that a circuit between the telephone line and the call forwarding device is interrupted. Upon receipt of an incoming call on the telephone line, the timed switching device and the caller identification signal receiver are activated. The timed switching device enters a second, closed state after a finite amount of time has elapsed such as, for example, several seconds, thereby allowing sufficient time for the caller identification signal to arrive on the incoming telephone line. The caller identification signal receiver responds to the receipt of incoming caller identification information by immediately activating the timed switching device, placing the timed switching device into the second state. The call forwarding device, responsive to the caller identification signal receiver, connects the incoming telephone call to a selected telephone set.
