Abstract

A remote controlled telephone handset that allows an end user to remotely dial one of at least two telephone numbers stored in the handset. The handset includes a receiver that receives a remote control signal and a memory circuit that is adapted to store at least two telephone numbers. The telephone handset also has a off hook and ring detection circuit that can couple the handset to a telephone line. The receiver, memory and off hook and ring detection circuit are coupled to a central processing unit which can answer an incoming call, hang up a call, or dial one of the telephone numbers in response to the receipt of a control signal(s).

1. A remote controlled telephone handset that is coupled to a telephone line and can be operated with a remote control signal, comprising:

a receiver that receives the remote control signal;

a memory device that is adapted to contain a first telephone number and a second telephone number;

an off hook and ring detection circuit that is coupled to the telephone line; and

,

a central processing unit that is coupled to said memory device, said receiver and said off hook and ring detection circuit, said central processing unit scans said memory device upon the receipt of the remote control signal, said central processing unit initiates a dialing of the first telephone number if a subsequent remote control signal is received within a predetermined time interval and initiates a dialing of the second telephone number if the subsequent remote control signal is not received within the predetermined time interval.

2. The handset as recited in claim 1, further comprising a remote controller that transmits the remote control signal.

3. The handset as recited in claim 2, wherein said receiver is a radio frequency receiver that receives the remote control signal.

4. The handset as recited in claim 1, wherein said central processing unit switches said off hook and ring detection circuit to an off hook state when said receiver receives at least one remote control signal.

5. The handset as recited in claim 1, wherein said central processing unit switches said off hook and ring detection circuit to an on hook state when said receiver receives at least one remote control signal.

6. A method for remotely dialing a telephone number, comprising:

a) sending a remote control signal;

b) receiving said remote control signal; and

,

c) scanning a first telephone number and a second telephone number that are stored in a memory device;

d) dialing the first telephone number if a subsequent remote control signal is sent and received within a predetermined time interval; and
