Abstract

A method of detecting a problem in a communication network that supports at least one communication service communication service is provided. The method includes disconnecting a suspect component from the network, and replacing the suspect component with a diagnostic component configured to have the same network identification information as the suspect component. The method also includes determining if the problem still exists, and identifying the suspect component as defective if the problem no longer exists. In addition, the method includes identifying the problem as being caused by another part of the network besides the suspect component, if the problem still exists. An apparatus, system, and computer program are also provided for carrying out the method.

Claims

1. A method of detecting a problem in a communication network that supports at least one communication service, the method comprising:

disconnecting a suspect component from the network where the suspect component has network identification information;

replacing the suspect component with a diagnostic component configured to have the same network identification information as the suspect component;

determining if the problem still exists;

identifying the suspect component as defective if the problem no longer exists; and

identifying the problem as being caused by another part of the network besides the suspect component, if the problem still exists.

2. A method as set forth in claim 1, wherein the at least one communication service includes at least one of a voice service, a data service, and a video service.

3. A method as set forth in claim 1, wherein the suspect component is a customer Optical Network Terminal (ONT) and the diagnostic component is a diagnostic ONT having the same network identification information as the customer ONT.

4. A method as set forth in claim 1, wherein the replacing includes:

connecting the diagnostic component in the network in place of the suspect component; and

configuring the diagnostic component to have the same network identification information as the suspect component.

5. A method as set forth in claim 4, wherein the configuring includes

connecting a diagnostic terminal to a console interface of the diagnostic component;

issuing instructions from the diagnostic terminal to the diagnostic component, wherein the instructions contain the same network identification information as the suspect component; and

storing the network identification information.

6. A method as set forth in claim 5, wherein the network identification information includes a serial number and a physical layer operation and maintenance (PLOAM) password.

7. A method as set forth in claim 6, further comprising:

synchronizing the diagnostic component with another component of the network that recognizes the same network identification information as the suspect component; and

configuring the diagnostic component to provide network services.

8. A diagnostic network component, comprising:

a processor;

a memory coupled to the processor; and

a console interface coupled to the processor and the memory, the console interface adapted to receive applied information and forward it to the memory for storage therein,

wherein the applied information identifies the diagnostic network apparatus with the same information as at least one suspect component of a network.

9. The apparatus of claim 8, further comprising a power supply interface.

10. The apparatus of claim 9, further comprising:

a network interface to connect the diagnostic network component to a network; and

at least one service interface for connecting the diagnostic network component to customer equipment.

11. The apparatus of claim 10, wherein a service interface includes

a telephone service interface;

a television service interface; and

a data service interface.

12. The apparatus of claim 8, wherein the diagnostic network component is configured to selectively operate in a reduced low power mode.

13. The apparatus of claim 12, wherein the reduced low power mode can be disabled.

14. The apparatus of claim 8, wherein the console interface is a serial interface.

15. The apparatus of claim 8, wherein the diagnostic network component is portable.

16. The apparatus of claim 8, wherein the diagnostic network component functions as an optical network terminal (ONT) in a passive optical network (PON).

17. The apparatus of claim 8, wherein the applied information includes a serial number and a physical layer operation and maintenance (PLOAM) password.

18. A diagnostic system comprising:

a diagnostic network component, comprised of;

a processor,

a memory coupled to the processor,

a console interface coupled to the processor and the memory,

the console interface adapted to receive applied information and forward it to the memory for storage therein,

wherein the applied information identifies the diagnostic network apparatus with the same identifier as at least one suspect component of a network; and

a diagnostic terminal in communication with the diagnostic network component via the console interface, wherein the applied information is transmitted to the diagnostic network component from the diagnostic terminal across the console interface.

19. The system of claim 18, wherein the diagnostic network component is configured to selectively operate in a reduced low power mode.

20. The system of claim 19, wherein the reduced low power mode can be disabled.

21. The system of claim 18, wherein the console interface is a serial interface.
