Saccadic eye movements to targets defined by structure differences

Described herein is a call diversion system for receiving a telephone call, dialing out a different number through a second line and linking the two lines. When identification is needed, an identification code is likewise transmitted subsequent to dial-out. A conversation monitor detects absence of communication to permit a timer to run for testing whether temporary interruption of a line evokes dial tone to reset the system. The number to be dialed out can be reprogrammed locally or remotely by sending signals into the system. The number to be dialed out is held in a memory having, for example, individually addressable locations. Automatic dial-out proceeds by a counting process for accurately timing dial pulses and pauses. During operation memory address sequences alternate with dial tone search phases. A subscriber can initiate an immediate dial-out from a remote location. The system diverts calls immediately in the operate mode but defers diversion in the standby mode, giving the user opportunity to answer the phone directly.
