Abstract

A system combining LAN and telecommunication capabilities to provide a high speed wireless LAN capability and to simultaneously provide wireless ISDN capability within an office. The LAN and ISDN information is communicated over a common transmission medium. The system also allow a user to interconnect wireless ISDN digital terminals to any other ISDN equipment anywhere in a PBX switch system or the public network. The system provides for communication of information between wireless LAN units and ISDN equipment. For example, this function allows a local computer using a local LAN interface to communicate with a remote computer via ISDN switching facilities. Further, the expense of hiding unsightly wiring in an office environment can be avoided, and the cost of moves and rearrangements of equipment can be greatly minimized.

Claims

1. An apparatus for simultaneously supporting communication among telecommunication units responsive to a telecommunication protocol and other units responsive to another protocol, comprising:

means in each of said telecommunication units for communicating telecommunication-protocol-defined data in a first portion of one of a plurality of frames communicated via a wireless medium;

means in each of said other units for communicating other-protocol-defined data in a second portion of said one of said plurality of frames;

means for determining first telecommunication-protocol-defined data and first other-protocol-defined data to be communicated with a telecommunication system;

means for converting said determined first other-protocol-defined data to telecommunication-protocol-defined data and the converted determined first other-protocol-defined data with said first telecommunication system;

means for determining second telecommunication-protocol-defined data that is to be communicated directly to a one of the telecommunication units;

means for directly communicating the determined second telecommunication-protocol-defined data to the one of the telecommunication units;

means for determining second other-protocol-defined data that is to be communicated directly to a one of the other units; and

means for directly communicating the determined second other-protocol-defined data to the one of the other units.

2. The apparatus of claim 1 wherein said first portion of said one of said plurality of frames comprises two time slots for each telecommunication protocol channel used by said telecommunication units.

3. The apparatus of claim 2 wherein said second portion of said one of said plurality of frames provides both data and control signaling for said other units in accordance with said other protocol.

4. The apparatus of claim 3 wherein said wireless medium is a photonic transmission medium.

5. The apparatus of claim 3 wherein said wireless medium is a radio transmission medium.

6. An apparatus for simultaneously supporting communication among telecommunication units using an ISDN protocol and LAN units using a LAN protocol, comprising:

means in each of said telecommunication units for communicating ISDN-protocol-defined data in a first portion of one of a plurality of frames communicated via a wireless medium;

means in each of said LAN units for communicating LAN-protocol-defined data in a second, portion of said one of said plurality of frames;

means for determining first ISDN-protocol-defined data and first LAN-protocol-defined data to be communicated with a telecommunication system;

means for converting said determined first LAN-protocol-defined data to ISDN-protocol-defined data for communication with said telecommunication system;

means for communicating the determined first ISDN data and the converted determined first LAN-protocol-defined data with said telecommunication system;

means for determining second ISDN-protocol-defined data that is to be communicated directly to a one of the telecommunication units;

means for directly communicating the determined second ISDN-protocol-defined data to the one of the telecommunication units;

means for determining second LAN-protocol-defined data that is to be communicated directly to a one of the other units; and

means for directly communicating the determined second LAN-protocol-defined data to the one of the other units.

7. The apparatus of claim 6 wherein said first portion of said one of said plurality of frames comprises two time slots for each ISDN channel used by said telecommunication units.

8. The apparatus of claim 7 wherein said second portion of said one of said plurality of frames provides both data and control signaling for said LAN units in accordance with said LAN protocol.

9. The apparatus of claim 8 wherein said wireless medium is a photonic transmission medium.

10. The apparatus of claim 8 wherein said wireless medium is a radio transmission medium.

11. A method for simultaneously supporting communication among telecommunication units responsive to a telecommunication protocol and other units responsive to another protocol, comprising the steps of:

communicating by each of said telecommunication units telecommunication-protocol-defined data in a first portion of one of a plurality of frames communicated via a wireless medium;

communicating other-protocol-defined data by each of said other units in a second portion of said one of said plurality of frames;

determining first telecommunication-protocol-defined data and first other-protocol-defined data to be communicated with a telecommunication system;

converting said determined first other-protocol-defined data to telecommunication-protocol-defined data for communication with said telecommunication system;

communicating the determined first telecommunication-protocol-defined data and the converted determined first other-protocol-defined data with said telecommunication system;

determining second telecommunication-protocol-defined data that is to be communicated directly to a one of the telecommunication units;

directly communicating the determined second telecommunication-protocol-defined data to the one of the telecommunication units;

determining second other-protocol-defined data that is to be communicated directly to a one of the other units; and

directly communicating the determined second other-protocol-defined data to the one of the other units.

12. The method of claim 11 wherein said first portion of said one of said plurality of frames comprises two time slots for each telecommunication protocol channel used by said telecommunication units.

13. The method of claim 12 wherein said second portion of said one of said plurality of frames provides both data and control signaling for said other units in accordance with said other protocol.

14. The method of claim 13 wherein said wireless medium is a photonic transmission medium.

15. The method of claim 13 wherein said wireless medium is a radio transmission medium.

16. A method for simultaneously supporting communication among telecommunication units using an ISDN protocol and LAN units using a LAN protocol, comprising the steps of:

communicating by each of said telecommunication units ISDN-protocol-defined data in a first portion of one of a plurality of frames communicated via a wireless medium;

communicating by each of said LAN units LAN-protocol-defined data in second portion of said one of said plurality of frames

determining first ISDN-protocol-defined data and first LAN-protocol-defined data to be communicated with a telecommunication system;

converting said determined LAN-protocol-defined data to ISDN-protocol-defined data for communication with said telecommunication system;

communicating the determined first ISDN-protocol-defined data and the converted determined first LAN-protocol-defined data with said telecommunication system;

determining second ISDN-protocol-defined data that is to be communicated directly to a one of the telecommunication units;

directly communicating the determined second ISDN-protocol-defined data to the one of the telecommunication units;

determining second LAN data that is to be communicated directly to a one of the other units; and

directly communicating the determined second LAN data to the one of the other units.
