Abstract

A facsimile forwarding phone system for receiving, storing and transmitting facsimile data includes a facsimile forwarding device that receives, stores and transmits facsimile data to a remote destination device. The facsimile forwarding device generates simulated public switched telephone network (PSTN) signals and outputs them over the telephone line to the destination device, so that it appears to the destination device that it is directly attached to the public switched telephone network. The facsimile forwarding device generates a ring signal and sends it over the phone line to the destination device. Thus, it appears to the destination device that it is directly connected to the public switched telephone network, rather that to the facsimile forwarding device. The destination device may include remote facsimile machines and remote computer systems. The stored facsimile data is transmitted upon the facsimile forwarding phone system receiving a forwarding request. The forwarding request can be input on an input panel of the facsimile forwarding device or remotely.

Claims

1. A facsimile forwarding phone system comprising:

a facsimile forwarding device capable of receiving facsimile data, storing the facsimile data and transmitting the stored facsimile data;

a first connector for connecting the facsimile forwarding device to a public switched telephone network, the fax forwarding device receiving the facsimile data from the public switched telephone network; and

a second connector for connecting the facsimile forwarding device to a destination device capable of receiving facsimile data, the fax forwarding device transmitting the received and stored fax data to the destination device;

wherein the facsimile forwarding device comprises;

an input circuit for inputting facsimile data from the first connector;

a storage circuit for storing the received facsimile data; and

a simulated telephone line interface for generating and outputting public switched telephone signals to the second connector and for outputting the received and stored facsimile data to the second connector in response to a received forwarding request.

3. The facsimile forwarding phone system according to claim 1, wherein the destination device comprises a computer system.

4. The facsimile forwarding phone system according to claim 1, wherein the facsimile forwarding device comprises a printing device for locally printing stored facsimile data.

5. The facsimile forwarding phone system according to claim 1, further comprising an input panel.

2. The facsimile forwarding phone system according to claimed 1, wherein the destination device comprises a facsimile machine.

6. A method for receiving, storing and transmitting facsimile data, comprising the steps of:

connecting a facsimile forwarding device to an external telephone line;

receiving an incoming transmission of facsimile data from the external telephone line and storing the received facsimile data;

receiving a forwarding request;

connecting a signal transmission cable directly between the facsimile forwarding device and a destination device;

simulating public switched telephone network signals, including a ring signal, on the signal transmission cable;

detecting when the destination device answers the ring signal; and

transmitting the received and stored facsimile data over the signal transmission cable to the destination device using the public switched telephone network signals in response to the received forwarding request.

7. The method according to claim 6, further comprising the step of printing the received and stored facsimile data using the facsimile forwarding device.

8. A facsimile forwarding phone system for receiving facsimile data, storing the facsimile data and transmitting the received and stored facsimile data, comprising:

facsimile forwarding means for receiving the facsimile data, storing the facsimile data and transmitting the facsimile data;

first connecting means for connecting the facsimile forwarding means to an external telephone line;

second connecting means for connecting the facsimile forwarding means to a destination device; and

simulated telephone line means for simulating a public switched telephone network telephone line between the facsimile forwarding means and the destination device;

wherein the facsimile forwarding means transmits the received and stored facsimile data to the destination device via the simulated telephone line means and the second connection means in response to a received forwarding request.

9. The facsimile forwarding phone system according to claim 8, further comprising a local input panel.

10. The facsimile forwarding phone system according to claim 8, wherein the destination device comprises a facsimile machine.

11. The facsimile forwarding phone system according to claim 8, wherein the destination device comprises a computer system.

12. The facsimile system according to claim 8, wherein the facsimile forwarding means comprises printing means for locally printing the stored facsimile data.
