DESCRIPTION:

BRIEF SUMMARY
TECHNICAL FIELD

The invention pertains to the general field of telephone switch enhancement systems and more particularly to a system that allows an incoming telephone call reaching a first telephone to be changed and call forwarded to a second telephone where the call forwarded number may be selected and changed from a third telephone at a remote location.


BACKGROUND ART

The use of call forwarding, which is also known as call tranferring or call diverting, as offered by the various telephone companies has gained wide range acceptance. This acceptance is especially true in the business community where the service, in many cases, has become indispensable. A call forwarding system functions by allowing an incoming telephone call arriving at a first telephone to be transferred or forwarded to a second telephone having a different telephone number. Thus, the person making the telephone number change is assured that any calls received by the first telephone will be transferred to the second telephone where the person is now located.
The prior art call forwarding or call diverting system as disclosed, are generally more complex with respect to their electronic circuits and associated parts count. This complexity decreases the product reliability and increases maintainability costs. Complexity and cost is further increased by the requirement that these systems have two telephone lines to function.
Other product problems that are prevalent to prior art call forwarding systems include: various dial tones, which in many cases will abort the incoming calls,
A search of the prior art did not disclose any patents that read directly on the claims of the instant invention, however, the following U.S. patents were considered related:


______________________________________ U.S. PAT. NO. INVENTOR ISSUED ______________________________________ 3,959,600 Sousa 28 May 1976 3,704,346 Smith, et al 28 November 1972 ______________________________________
The Sousa patent discloses a remotely programmable telephone call forwarding and switching device that requires two telephone lines to operate. The device has the capability to answer telephone calls, bridge telephone lines, dial preprogrammed numbers, program its memory locally and remotely and to confirm the newly programmed number. Circuitry is also included to allow the device to be used within telephone systems having diverse equipment and operational capabilities.
The Smith etal patent discloses a call diversion system for receiving a telephone call, dialing out a different number through a second line and linking the two lines. The dial out number can be reprogrammed locally or remotely by sending signals into the system. Automatic dial-out proceeds by a counting process that times the dial pulses and pauses. The system is designed to divert calls immediately when in the operate mode and defers diversion when in the standby mode. Thus, giving the user the opportunity to answer the phone directly.


DISCLOSURE OF THE INVENTION

The remotely commanded telephone switch enhancing system is designed to enhance the utility of the telephone call forwarding service by allowing the following three call forwarding functions to be performed from a remotely located telephone:
One of the advantages of the inventive system is that only a single Telephone Central Office (TCO) telephone line and a single TOUCHTONE.RTM. telephone set are required to perform the remotely programmed call forwarding functions. TOUCHTONE is a registered trademark of American Telegraph and Telephone Inc. (AT&T) of New York, United States of America.
The remote call forwarding and call transferring systems disclosed in the prior art have to distinct disadvantages--they utilize a more complex design and they require two telephone lines to remotely program and to change the current call forwarded telephone number. The only limitation imposed on the instant system is that the local telephone set be connected to a telephone line having the call forwarding service as provided by the telephone company.
