Abstract
A remotely commanded switch enhancing system (10) that is designed to enhance the utility of the telephone call forwarding service. The system (10) functions in combiantion with a local telephon set (40) that is connected to a single telephone line. The system is comprised of a set of electronic circuits that operates with a CPU (20) and firmware (30) to allow the initiation of call forwarding, changing the current call forwarded telephone number to another telephone number or the cancellation of the call forwarded number. One of the principal advantages of the system (10) is that only a single telephone line is required--unlike the prior art remote call forwarding devices where two telephone lines are required.
