Abstract
A telephone set of a telephone system is provided with an infrared interface. This infrared interface is able to communicate with an infrared port on a local computer. The computer is configured to send data to the infrared port, and receive data from the infrared port, in the same manner as if the computer was sending and receiving data over a telephone system. The telephone circuitry in the telephone system receives the infrared data and converts the infrared data into a format for transmitting across the telephone system.
Claims17
A telephone system comprising:
- a Local Area Network (LAN) operating a computer network protocol;
- a Private Branch Exchange (PBX) arranged in said LAN;
- a plurality of telephone sets connected to said LAN, each of said telephone sets including telephone circuitry for telephonically connecting one telephone user with another telephone user over said LAN using said computer network protocol;
- an infrared interface arranged in each of said telephone sets for infrared communication with a local computer device having an infrared port, said infrared interface transferring LAN data between the local computer device and said LAN using said computer network protocol.
A method for operating a telephone network, the method comprising the steps of:
- providing a Private Branch Exchange (PBX)/Local Area Network (LAN) with a plurality of telephone sets and operating a computer network protocol, said telephone sets having an infrared interface;
- providing a plurality of computer devices connected to said PBX/LAN, said plurality of computer devices communicating with each other over said PBX/LAN according to said computer network protocol;
- transferring telephone data telephonically between the telephone sets over said PBX/LAN using said computer network protocol;
- receiving LAN data from a local one of said plurality of computer devices at one of said infrared interfaces;
- transferring said LAN data over said PBX/LAN to another one of said plurality of computer devices.
A telephone system comprising:
- a telephone line connection for connecting to a telephone network, said telephone line connection is incorporated into a PSTN interface unit of Private Branch Exchange (PBX);
- a telephone set connected to said telephone line connection and including telephone circuitry for telephonically conning one telephone user with another telephone user over the telephone network;
- a PBX network connecting said telephone set with said PSTN interface unit said PBX network uses a computer network protocol to communicated between said PSTN interface unit and said telephone set;
- an infrared interface connected to said telephone set for infrared communicating with a local computer device having an infrared port said infrared interface transferring data between the local computer device and said telephone circuitry, said infrared interface detects Local Area Network (LAN) data from the local computer and configures the LAN data to be sent from said telephone set to computer network devices connected to said PBX network;
- a modem unit is arranged in said PSTN interface unit and connected to said telephone line connection, said modem unit converts the data from the local computer device received through said PBX network into PSTN signals, and converts PSTN signals from the telephone network into the data for the local computer device.
