Abstract

A telephone system wherein all the functions of a digital telephone can be accessed and implemented on a personal computer alone, thereby eliminating the need for a telephone set. By means of the computer display and mouse, keyboard or other input/output command devices, a user accesses and implement all digital telephone functions without the physical telephone set, the personal computer also providing the audio function. A graphical representation of a telephone set or other telephone-related form is provided on the computer display and accessed by the mouse, keyboard or other command device, this being accomplished by a computer program providing graphical interface implementation. A significant advantage of the system is computer access to and utilization of digital telephone functions from a remote location with communication via Internet, LAN, WAN, RAS or other mediums.

Claims

1. An apparatus, comprising:

an interface to connect to a synchronous digital link and to send and receive digital signals to and from a telephone switch over the synchronous digital link;

a controller to generate graphical display information and events based on the digital signals received over the interface; and

logic to communicate over an asynchronous digital link, to convert the digital signals to an asynchronous format, and to transmit the digital signals and the graphical display information and events over the asynchronous digital link, wherein the logic is arranged to receive key press and hook state commands over the asynchronous digital link.

2. The apparatus of claim 1, wherein the logic is arranged to display a digital telephone on a display device, the digital telephone including the graphical display information and events.

3. A method, comprising:

receiving digital data from a public branch exchange (PBX) over a synchronous digital communication link;

generating graphical display information and events based on the received digital data;

transmitting the graphical display information and events over an asynchronous Internet protocol (IP) link;

receiving a key press and hook state command over the asynchronous Internet protocol (IP) link;

translating the key press and hook state command to a different format; and

transmitting the translated key press and hook state command to the PBX over the synchronous digital communication link.

4. The method of claim 3, wherein the graphical display information is related to graphical representation of a digital telephone.

5. The method of claim 3, further comprising:

graphically representing a digital telephone on a display device, the digital telephone including the graphical display information.

6. A computer readable medium including instructions that, when executed, cause a computer to:

convert received light events and display updates to a graphical format;

cause a first display device to display a digital telephone including the light events and display updates;

convert received input device data that is related to the displayed digital telephone into a packetized format, wherein the input device data includes a key press and hook state commands over asynchronous Internet protocol (IP) link; and

transmit the packetized input device data over the asynchronous Internet protocol (IP) link.

7. The medium of claim 6, further comprising instructions that, when executed, cause the computer to:

emit audio information from a speaker that is received over the asynchronous IP link.

8. The medium of claim 6, further comprising instructions that, when executed, cause the computer to:

convert input voice data into a packetized format; and

transmit the packetized input data over the asynchronous IP link.
