Abstract

A network device for use in a communication system having a technical support center operated by a technical support staff, the technical support center being in communication with the network device through a packet switching network. The network device includes one or more hardware subsystems, one or more software subsystems and means for monitoring the status of the hardware and software subsystems so that when a problem occurs with respect to one or more of the hardware and software subsystems of the network device, the network device for transmitting a first message to the technical support center to notify the technical support center of the problem, wherein the technical support staff is able to diagnose the problem without interruption to the operation of the network device.

Claims

1. A method comprising:

communicating network information from an access server to a technical support center through a packet switching network;

analyzing status information from at least one of a hardware subsystem and a software subsystem of the access server prior to sending a first message to the technical support center;

detecting a problem with the at least one of the hardware subsystem or the software subsystem responsive to the analyzing prior to sending the first message to the technical support center;

sending a first message including the status information to the technical support center responsive to the detecting the problem;

responsive to the detecting the problem, sending an alert notification to a user of the access server, wherein the alert is a page or email message, or combination thereof;

responding to a second message generated by the technical support center requesting further information on the problem, wherein the second message comprises commands associated with the status information and wherein responding comprises executing the commands including instructions to perform further diagnostic testing of the at least one of the hardware subsystem or the software subsystem to provide additional details associated with the problem, wherein the further diagnostic testing is to be performed without interrupting the normal operation of the access server.

2. The method of claim 1 comprising:

communicating from the access server to the technical support center using a first interface line.

3. The method of claim 2 comprising:

coupling the at least one access server to the packet switching network using a second interface line.

4. The method of claim 1 comprising:

sending the first message including the status information to the technical support center without interrupting a normal operation of the access server.

5. The method of claim 1 where communicating the network information includes communicating through the Internet;

and

where sending the first message includes sending a first email.

6. The method of claim 1 where sending the first message includes sending a first fax.

7. An apparatus comprising a computer readable medium having instructions thereon that, when executed by a processor, result in:

communicating network information from an access server to a technical support center through a packet switching network;

analyzing status information from at least one of a hardware subsystem and a software subsystem of the access server prior to sending a first message to the technical support center;

detecting a problem with the at least one of the hardware subsystem or the software subsystem responsive to the analyzing;

sending a first message including the status information to the technical support center responsive to the detecting the problem;

responsive to the detecting the problem, sending an alert notification to a user of the access server, wherein the alert is a page or email message, or combination thereof; and

responding to a second message generated by the technical support center requesting further information on the problem, wherein the second message comprises commands associated with the status information and wherein responding comprises executing the commands including instructions to perform further diagnostic testing of the at least one of the hardware subsystem or the software subsystem to provide additional details associated with the problem, wherein the further diagnostic testing is to be performed without interrupting the normal operation of the access server.

8. The apparatus of claim 7 comprising:

communicating from the access server to the technical support center using a first interface line.

9. The apparatus of claim 8 comprising:

coupling the at least one access server to the packet switching network using a second interface line.

10. The apparatus of claim 7 comprising:

sending the first message including the status information to the technical support center without interrupting a normal operation of the access server.

11. The apparatus of claim 7 where communicating the network information includes communicating through the Internet;

and

where sending the first message includes sending a first email.

12. The apparatus of claim 7 where sending the first message includes sending a first fax.

13. A method of remotely diagnosing a problem, comprising:

monitoring a status of a hardware or software subsystems of a network device;

detecting a problem with at least one of the hardware or software subsystems responsive to the monitoring prior to sending a first message to a technical support center wherein the first message is a page or email message, or combination thereof sent responsive to detecting the problem;

transmitting the first message indicating the problem and the status of the at least one of the hardware or software subsystems to a geographically remote technical center through a packet switched network; and

detecting at least one of a memory capacity of the network device dropping below a first threshold level, a percentage of call failures to or from the network device exceeding a second threshold level, a software reload by the network device, a reduced quality of an interface on the network device, a temperature of the network device exceeding a third threshold level, and a failed interface on the network device;

sending additional information regarding the problem to the technical support center responsive to receiving a second message from the technical support center, the second message generated by the technical support center responsive to the first message,

wherein the second message comprises commands associated with the status information and wherein responding comprises executing the commands including instructions to perform further diagnostic testing of the at least one of the hardware subsystem or the software subsystem to provide additional details associated with the problem,

wherein the further diagnostic testing is to be performed without interrupting the normal operation of an access server.

14. The method of claim 13 comprising:

transmitting the first message indicating the problem while maintaining a normal operation of the network device.

15. The method of claim 13 comprising:

transmitting the first message indicating the problem responsive to a remote diagnostic embedded process subsystem detecting an error message from at least one of the hardware and software subsystems.

16. The method of claim 15 comprising:

collecting the status at a health status monitor included in the network device.
