Abstract

A telephone remote control system for direct control of the dialing sequence of a telephone from a personal computer. The remote control system includes an RF transmitter unit mounted on a personal computer and an RF receiver unit within a phone. The transmitter receives dialing commands from a personal computer and transmits those commands to a receiver unit via an RF signal. The receiver unit receives the dialing commands from the transmitter unit and directly controls the dialing sequence of the telephone.

Claims

1. A telephone remote control system for directly controlling the dialing sequence of a telephone from a computer, the telephone including keys and circuitry, said control system comprising:

a transmitter unit including;

connector means for mechanically connecting said transmitter unit to a communications port of the computer,

input means for receiving dialing commands from the computer, and

transmitter means for transmitting the dialing commands from said transmitter unit using wireless communication technology; and

a receiver unit including;

connector means for electrically connecting said receiver unit to the circuitry of the telephone,

receiver means for receiving said dialing commands transmitted by said transmitter unit, and

control means for directly causing the telephone circuitry to execute the dialing commands by emulating manual operation of the telephone keys automatically in response to receiving the dialing commands.

2. The telephone remote control system of claim 1, wherein said wireless communication technology is radio frequency technology.

3. The telephone remote control system of claim 2, wherein said transmitter unit input means includes an RS-232 input port.

4. The telephone remote control system of claim 3, wherein the dialing commands follow a standard modem command instruction set.

5. The telephone remote control system of claim 4, wherein said transmitter means further includes means for transmitting a unique station identifier along with the dialing commands, said receiver means further including means for receiving the unique station identifier, and said receiver unit further including a receiver unit identifier and means for ignoring the dialing commands transmitted by said transmitter unit unless the unique station identifier transmitted along with the dialing commands matches the receiver unit identifier.

6. The telephone remote control system of claim 5, wherein said transmitter means further includes means for transmitting a checksum along with the unique station identifier and the dialing commands, said receiver means further including means for receiving the checksum, and said receiver unit further including means for checking the integrity of the dialing commands by verification of the checksum.

7. The telephone remote control system of claim 6, wherein the telephone includes a keypad and a keypad input jack, wherein said receiver unit control means includes means for interfacing said receiver unit with the telephone keypad input jack, wherein said receiver unit emulates the manual operation of the telephone keypad.

8. The telephone remote control system of claim 7, wherein said receiver unit further includes a keypad bypass means for connecting the telephone keypad to the telephone keypad input jack through said receiver unit, thereby allowing the telephone to receive dialing commands either remotely through said receiver unit or directly through said telephone keypad.

9. A telephone remote control system for directly controlling the dialing sequence of a telephone from a computer, wherein the computer includes a communications port, wherein the telephone includes a main circuit, a keypad, a keypad input jack, and a receiver for receiving incoming transmissions over a telephone connection, said system comprising:

a transmitter unit including;

connector means for mechanically connecting said transmitter unit to the communications port of the computer,

input means for receiving dialing commands from the computer,

transmitter control means for creating a data packet including the dialing commands, a unique station identifier, and a checksum, and

transmitter means for transmitting the data packet using wireless communication technology; and

a receiver unit separate from the receiver of the telephone, said receiver unit including;

connector means for connecting said receiver unit to the telephone,

receiver means for receiving the data packet transmitted by said transmitter unit, and

receiver control means for ignoring said data packet unless the station identifier transmitted therein matches a unique station identifier assigned to said receiver unit, for checking the integrity of the data packet by verification of the checksum of the data packet, and for directly causing the main circuit to execute the dialing sequence immediately in response to receiving an assigned, verified data packet.

10. The telephone remote control system of claim 9, wherein said wireless communication technology is radio frequency technology.

11. The telephone remote control system of claim 10, wherein said transmitter unit input means includes an RS-232 input port.

12. The telephone remote control system of claim 11, wherein the dialing commands follow a standard modem command instruction set.

13. The telephone remote control system of claim 12, wherein said receiver unit interfaces directly with the telephone main circuit.

14. The telephone remote control system of claim 11, wherein said receiver unit control means includes means for interfacing said receiver unit with the telephone keypad input jack, wherein said receiver unit emulates the manual operation of the telephone keypad.

15. The telephone remote control system of claim 14, wherein said receiver unit further includes a keypad bypass means for connecting the telephone keypad to the telephone keypad input jack through said receiver unit, thereby allowing the telephone to receive dialing commands either remotely through said receiver unit or directly through said telephone keypad.

16. A computer controlled phone dialing system comprising:

a transmitter unit including connector means for operatively connecting said transmitter unit to a communications port on a computer, receiving means connected to said connector means for receiving information indicative of a telephone number to be dialed, and transmitter means for transmitting the information via a wireless signal; and

a receiver unit including connector means for operatively connecting said receiver unit to the internal circuitry of a telephone, receiving means for receiving the wireless signal and embodied information transmitted by said transmitter unit, and control means responsive to the information for issuing dialing commands to the telephone circuitry by electrically emulating the manual operation of the telephone'"'"'s keys causing the circuitry to dial the telephone number.

17. The computer controlled phone dialing system of claim 16 wherein:

each of said transmitter unit and said receiver unit are assigned the same unique station identifier;

the RF signal includes the unique identifier; and

said control means within said receiver unit includes means for ignoring any RF signal not containing the unique identifier, whereby said receiver unit is responsive only to said transmitter unit in an environment where multiple transmitter units may be present.

18. The computer controlled phone dialing system of claim 16 wherein said receiver unit is adapted to be connected between the keypad connector and the keypad jack of the telephone, whereby the phone can be dialed using either remotely through said computer controlled phone dialing system or directly through the telephone keypad.
