Abstract

A method of multiplexing multiple terminals in a distributed network includes transporting user traffic and telephony signaling information. Transporting user traffic includes converting the user traffic into ATM cells, passing the ATM cells over a wireless link to a TDM port in an ATM multiplexer wherein the ATM multiplexer includes an ATM circuit emulation service, and converting the ATM cells into user traffic. Transporting telephony signaling information includes extracting the telephony signaling information from a user interface, passing the telephony signaling information to a base station using an ATM virtual circuit, processing and aggregating a number of telephony signaling information into a single channel, and transmitting the single channel to the ATM multiplexer.

Claims

1. A method of multiplexing multiple terminals in a distributed network, the method comprising:

transporting user traffic, comprising;

converting said user traffic into ATM cells;

passing said ATM cells over a wireless link to a TDM port in an ATM multiplexer, said ATM multiplexer including an ATM circuit emulation service; and

converting said ATM cells into user traffic; and

transporting telephony signaling information, comprising;

extracting said telephony signaling-information from a user interface;

passing said telephony signaling information to a base station using an ATM virtual circuit;

processing and aggregating a plurality of telephony signaling information including said telephony signaling information into a single channel; and

transmitting said single channel to said ATM multiplexer including said ATM circuit emulation service.

2. A method as in claim 1, wherein said processing is performed in accordance with any telephony standards, said telephony standards including V5.1, V5.2, TR303, or ISDN PR1.

3. A method as in claim 1, wherein said converting said user traffic into ATM cells is performed by a subscriber terminal.

4. A method as in claim 1, wherein said passing said ATM cells is performed by a subscriber terminal.

5. A method as in claim 1, wherein said converting said ATM cells into user traffic is performed by said ATM multiplexer.

6. A method as in claim 1, wherein said extracting said telephony signaling information is performed by a subscriber terminal.

7. A method as in claim 1, wherein said passing said telephony signaling information is performed by a subscriber terminal.

8. A method as in claim 1, wherein said processing and aggregating said plurality of telephony signaling information is performed by said base station.

9. A method as in claim 1, wherein said transmitting said single channel is performed by said base station.

10. A method as in claim 1, wherein said base station is coupled to said ATM multiplexer through a trunk.

11. A method as in claim 1, wherein said plurality of telephony signaling information includes another telephony signaling information from another user interface.
