DETAILED DESCRIPTION The present invention comprises an improved telephone system with additional features that enable a user or users to make more effective use of their telephone service.
The present invention comprises a method for automatically updating a clock using caller ID information.
The method comprises the steps of receiving an incoming telephone call from a caller, receiving caller ID information that includes the time of the incoming telephone call along with the telephone signal, decoding the caller ID information to obtain the time of the incoming telephone call, transmitting the time of the incoming telephone call to a clock, the clock receiving the time of the incoming telephone call, and the clock updating the time used by the clock using the received time of the incoming telephone call.
The present invention further comprises a system for updating a clock using caller ID information.
The system includes a telephone port for coupling to a telephone line for receiving a telephone signal, a caller ID decoder that receives the telephone signal from the telephone port and determines the time of the incoming telephone call from information included in the telephone signal, and a clock that receives the time of the incoming telephone call from the decoder and uses it to update the current time used by the clock.
The clock may display the current time or it may use the current time for other purposes, such as time-stamping.
The clock may be located in the same unit as the caller ID decoder, or it may be located in a remote device.
Still further, the present invention comprises a system for generating a time signal using caller ID information.
The system includes a telephone port for coupling to a telephone line for receiving a telephone signal, a caller ID decoder that receives the telephone signal from the telephone port and determines the time of the incoming telephone call from information included in the telephone signal, and an output port that receives the time of the incoming call from the decoder
