Abstract

A method for managing operator services comprises the steps of: converting a plurality of voice calls between a public switched telephone network (PSTN) and respective operator work stations in an operator service local area network (LAN) into digital voice data; respectively transmitting the voice data between the PSTN and the respective operator work stations over single digital data transmission lines; respectively transmitting requests for operator services data and operator services data between a data center LAN and respective ones of the operator work stations over the single digital data transmission lines; respectively transmitting operator activity data between an operator registration server on the data center LAN and respective ones of the operator work stations over the single digital data transmission lines; and, multiplexing and demultiplexing the voice data and at least one of the data requests, requested data and the activity data for simultaneous transmission over respective ones of the single digital data transmission lines.

Claims

1. A method for managing operator services, comprising the steps of:

converting a voice call between a public switched telephone network (PSTN) and a selected operator work station in an operator center local area network (LAN) into digital voice data;

transmitting said voice data between said PSTN and said selected operator work station over a single digital data transmission line;

transmitting caller data information and operator requests for caller data information between a data center LAN and said selected operator work station over said single digital data transmission line; and

,

transmitting operator activity data for identifying an available operator between an operator registration server on said data center LAN and said selected operator work station over said single digital data transmission line.

2. The method of claim 1, further comprising the step of multiplexing and demultiplexing said voice data and at least one of said requests for caller data information, said caller data information and said operator activity data.

3. The method of claim 2, wherein said multiplexing and demultiplexing step is performed in a voice and data interface between said single digital data transmission line and said operator center LAN.

4. The method of claim 2, wherein said multiplexing and demultiplexing step is performed in a voice and data interface between said single digital data transmission line and each one of said PSTN and said data services LAN.

5. The method of claim 2, wherein said multiplexing and demultiplexing step is performed in a first voice and data interface between one end of said single digital data transmission line and each one of said PSTN and said data services LAN and in a second voice and data interface between an opposite end of said single digital data transmission line and said operator center LAN.

6. The method of claim 1, further comprising the sum of demultiplexing said voice data and at least one of said requested data and said activity data transmitted to said operator services LAN over said single digital data transmission line in a switch, said switch directing said demulitplexed streams of said voice data, said requested data and said activity data to said selected work station.

7. The method of claim 6, wherein said demultiplexing step is implemented in an asynchronous transfer mode (ATM) switch.

8. The method of claim 1, further comprising the step of demultiplexing said voice data and at least one of said requests for caller data information and said operator activity data transmitted over said single digital transmission line from said operator center LAN in a voice and data interface, said voice and data interface routing said demultplexed voice data to said PSTN and routing said requests for caller data information to said data center LAN.

9. The method of claim 1, further comprising the steps of:

compressing said converted voice data for transmission over said single data transmission line; and

,

decompressing said voice data after transmission over said single data transmission line.

10. The method of claim 9, wherein said compressing and decompressing steps are implemented in said selected work station and at an end of said single data transmission line remote from said operator services LAN.

11. A method for managing operator services, comprising the steps of:

converting a plurality of voice calls between a public switched telephone network (PSTN) and respective operator work stations in an operator center local area network (LAN) into digital voice data;

respectively transmitting said voice data between said PSTN and said respective operator work stations over single digital data transmission lines;

respectively transmitting requests for caller data information and caller data information between a data center LAN and respective ones of said operator work stations over said single digital data transmission lines; and

,

respectively transmitting operator activity data for identifying an available operator between an operator registration server on said data center LAN and respective ones of said operator work stations over said single digital data transmission lines.

12. The method of claim 11, further comprising the steps of multiplexing and demultiplexing said voice data and at least one of said requests for caller data information, requested caller data information and said operator activity data for simultaneous transmission over respective ones of said single digital data transmission lines.

13. The method of claim 12, wherein said multiplexing and demultiplexing step is performed in a voice and data interface between said single digital data transmission lines and said operator center LAN.

14. The method of claim 12, wherein said multiplexing and demultiplexing step is performed in a voice and data interface between said single digital data transmission lines and each one of said PSTN and said data services LAN.

15. The method of claim 12, wherein said multiplexing and demultiplexing step is performed in a first voice and data interface between respective first ends of said single digital data transmission lines and each one of said PSTN and said data services LAN and in a second voice and data interface between respective second ends of said single digital data transmission lines and said operator services LAN.

16. The method of claim 11, further comprising the step of demultiplexing said voice data and at least one of said requested caller data information and said operator activity data transmitted to said operator center LAN over said single digital data transmission lines in a switch, said switch directing said demulitplexed streams of said voice data and at least one of said requested caller data information and said operator activity data to said respective operator work stations.

17. The method of claim 16, wherein said demultiplexing step is implemented in an asynchronous transfer mode (ATM) switch.

18. The method of claim 11, further comprising the step of demultiplexing said voice data and at least one of said requests for caller data information and said operator activity data transmitted over said single digital data transmission lines from said operator center LAN in a voice and data interface, said voice and data interface routing said demulitplexed voice data to said PSTN and routing said requests for caller data information and said operator activity data to said data center LAN.

19. The method of claim 11, further comprising the steps of:

compressing said converted voice data for transmission over respective ones of said single data transmission lines; and

,

decompressing said voice data after transmission over said respective ones of said single data transmission lines.

20. The method of claim 19, wherein said compressing and decompressing steps are implemented in said work stations and at an end of said single data transmission lines remote from said operator services LAN.
