Abstract

To obtain its own copy of directory information from a database (111) of a switching system (10), an adjunct processor such as a voice-mail system (11) either uses the "directory" feature of the switching system by emulating use of the feature by a digital display telephone (140), or uses a remote administration and maintenance port (119) by emulating use of the port by a remote administration terminal (145).

Claims

1. A method of obtaining switching system database information at an adjunct processor, comprising the steps of:

interacting with a switching system from an adjunct processor by simulating interaction of a terminal with the switching system by means of which interactions the terminal requests and obtains access to contents of a database of the switching system, including

signaling to the switching system a desire to access the database, in a same manner as the terminal signals to the switching system the desire to access the database, and

signaling to the switching system a desire to have the switching system sequentially retrieve and provide to the adjunct processor each item of the database without directly identifying to the switching system any particular item of the database, in a same manner as the terminal signals to the switching system the desire to have the switching system sequentially retrieve and provide to the terminal each item of the database without directly identifying to the switching system any particular item of the database; and

in response to the interacting, receiving the contents of the database from the switching system at the adjunct processor for use by the adjunct processor.

2. The method of claim 1 further comprising the step of:

in response to the receiving, populating a database of the adjunct processor with the received contents for future use of the contents by the adjunct processor.

3. The method of claim 1 wherein

the step of interacting comprises the step of:

interacting with the switching system in a same manner as a telephone station set and invoking a directory feature of the switching system to obtain directory information from the database of the switching system.

4. The method of claim 1 wherein

the step of interacting comprises the step of:

interacting with the switching system through a remote maintenance and administration port in a same manner as an administration terminal to obtain subscriber records from the database of the switching system.

5. The method of claim 1 wherein

the step of receiving comprises the step of:

receiving from the switching system both extension numbers and corresponding subscriber names of subscribers served by the switching system.

11. The method of claim 1 wherein

the step of signaling a desire to access the database comprises the step of

sending to the switching system a database-access request for said database, and

the step of signaling a desire to have the switching system sequentially retrieve and provide each item of the database comprises the step of

sending to the switching system a series of next-item requests.

12. The method of claim 3 wherein

the step of signaling a desire to access the database comprises the step of

sending to the switching system a directory-access request, and

the step of signaling a desire to have the switching system sequentially retrieve and provide each item of the database comprises the step of

sending to the switching system a series of next-item requests.

13. The method of claim 4 wherein

the step of signaling a desire to access the database comprises the step of

sending to the switching system a station-information database-access request, and

the step of signaling a desire to have the switching system sequentially retrieve and provide each item of the database comprises the step of

sending to the switching system a series of next-page requests.

6. An adjunct processor for use with a switching system comprising:

means for performing adjunct processing functions;

means for interacting with a switching system by simulating interactions of a terminal with the switching system by means of which interactions the terminal requests and obtains access to contents of a database of the switching system, including

means for signaling to the switching system a desire to access the database, in a same manner as the terminal signals to the switching system the desire to access the database, and

means for signaling to the switching system a desire to have the switching system sequentially retrieve and provide to the adjunct processor each item of the database without directly identifying to the switching system any particular item of the database, in a same manner as the terminal signals to the switching system the desire to have the switching system sequentially retrieve and provide to the terminal each item of the database without directly identifying to the switching system any particular item of the database; and

means cooperative with the interacting means and the performing means for receiving the contents of the database from the switching system for use by the performing means.

7. The adjunct processor of claim 6 wherein

the receiving means comprise:

a database for storing the received contents for future use of the received contents by the performing means.

8. The adjunct processor of claim 6 wherein

the interacting means comprise:

means for interacting with the switching system in a same manner as a telephone station set and invoking a directory feature of the switching system to obtain directory information from the database of the switching system.

9. The adjunct processor of claim 6 wherein

the interacting means comprise:

means for interacting with the switching system through a remote maintenance and administration port in a same manner as an administration terminal to obtain subscriber records from the database of the switching system.

10. The adjunct processor of claim 6 wherein

the receiving means comprise:

means for receiving from the switching system both extension numbers and corresponding subscriber names of subscribers served by the switching system.

14. The adjunct processor of claim 6 wherein

the means for signaling a desire to access the database comprise

means for sending to the switching system a database-access request for said database, and

the means for signaling a desire to have the switching system sequentially retrieve and provide each item of the database comprise

means for sending to the switching system a series of next-item requests.

15. The adjunct processor of claim 8 wherein

the means for signaling a desire to access the database comprise

means for sending to the switching system a directory-access request, and

the means for signaling a desire to have the switching system sequentially retrieve and provide each item of the database comprise

means for sending to the switching system a series of next-item requests.

16. The adjunct processor of claim 9 wherein

the means for signaling a desire to access the database comprise

means for sending to the switching system a station-information database-access request, and

the means for signaling a desire to have the switching system sequentially retrieve and provide each item of the database comprise

means for sending to the switching system a series of next-page requests.
