Abstract

Centralized call control includes establishing a communication channel in a multiple leg architecture by instructing each leg, in the architecture, forming a desired path within the architecture to use a same key for a communication channel.

Claims

1. A method of establishing a communication channel, comprising:

instructing each leg that forms a desired path within a multiple leg architecture to use a same key for a communication channel.

2. The method of claim 1, wherein the key comprises a VPI/VCI pair.

3. The method of claim 1, wherein the communication channel comprises a data packet channel.

4. The method of claim 1, wherein the communication channel comprises a circuit switched connection.

5. The method of claim 1, wherein the communication channel comprises a control channel.

6. The method of claim 1, wherein the communication channel comprises a operation and management channel.

7. The method of claim 1, wherein the communication channel comprises a testing channel.

8. The method of claim 1, wherein the instructing step comprises:

sending messages from a controller to the legs forming the desired path, each message indicating the key for the communication channel.

9. The method of claim 8, wherein at least one of the messages indicates physical connections for a leg to make for the communication channel.

10. The method of claim 1, wherein the instructing step is performed by a single controller in the architecture.

11. The method claim 1, further comprising:

maintaining a table of available keys for communication channels;

selecting one of the available keys; and

wherein

the instructing step instructs the legs forming the desired path within the architecture to use the selected available key for the communication channel.

12. The method of claim 11, wherein the maintaining step maintains a set of available key tables, each table associated with one of a plurality of different types of communication channels.

13. The method of claim 12, wherein the different types of communication channels comprises at least one of a control channel, a data packet channel, an operation and management channel and a testing channel.

14. The method of claim 12, wherein each available key table includes different keys from those in another of the available key tables.

15. The method of claim 12, wherein

the architecture includes a master shelf having a control module and a plurality of slots, each slot for receiving an operation module and the control module for selectively connecting to an operation module in one of the slots;

and

the maintaining step maintains a set of the available key tables for each slot.

16. The method of claim 15, wherein each available key table in a set of available key tables comprises different keys from those in another of the available key tables in the set of available key tables.

17. The method of claim 16, wherein at least one available key table comprises a same key as in an available key table in a different set of available key tables.

18. The method of claim 15, wherein at least one available key table comprises a same key as in an available key table in a different set of available key tables.

19. The method of claim 1, wherein the communication channel is for end-to-end communication.

20. The method of claim 1, wherein the communication channel is for terminated communication.
