Abstract

A system for provisioning a network access device based on control settings received from a remote location utilizes logic and memory for storing a set of operational control settings and a set of default control settings for the network access device. The logic is configured to store, in the memory, the operational control settings based on data received from a remote device via a network. The logic is configured to control the network access device based on the operational control settings and to begin controlling the network access device based on the default control settings in lieu of the operational control settings in response to a determination that the network access device is unable to communicate over the network based on the operational control settings, thereby enabling the network access device to be remotely re-provisioned.

2. The network access device of claim 1, wherein the logic is configured to control the operation of the device according to the default configuration while the logic is receiving the operational control settings from the remote device.

3. The network access device of claim 1, wherein the timer is configured to notify the logic of expiration of a specified time period provided that the timer is not deactivated prior to the expiration of the specified timer period, and wherein the logic is configured to transition to controlling the operation of the device according to the default configuration in response to a notification from the timer that the specified timer period has expired.

4. A communication system, comprising:

a communication network;

a network access device communicatively coupled to the communication network; and

a configuration manager located remotely from the network access device, the configuration manager configured to provision the network access device via communication with the network access device over the communication network thereby establishing an operational configuration for the network access device,

wherein the network access device is configured to automatically implement a predefined configuration if the network access device is unable to communicate over the network while operating pursuant to the operational configuration thereby enabling the network access device to be remotely re-provisioned.

5. The system of claim 4, wherein the network access device is configured to automatically implement the predefined configuration based on a timer.

6. The system of claim 4, wherein the network access device is configured to automatically establish a default route and to communicate with the configuration manager via the default route.

7. The system of claim 4, wherein the network access device comprises a timer, the timer configured to cause the network access device to implement the predefined configuration once a specified amount of time has elapsed since activation of the timer unless the timer is deactivated prior to the end of the specified amount of time.

8. The system of claim 7, wherein the configuration manager is configured to activate the timer during a communication session with the network access device.

9. The system of claim 7, wherein the timer is activated based on whether the configuration manager has provisioned the network access device.

10. The system of claim 7, wherein the configuration manager is configured to set the specified amount of time.

11. The system of claim 7, wherein the specified amount of time is sufficient for allowing a remote device to deactivate the timer between the end of the communication session and the end of the specified amount of time.

12. The system of claim 4, wherein the network access device has an identifier that identifies the network access device with respect to other network access devices communicating over the network, wherein the network access device is configured to automatically implement the predefined configuration after attempting to communicate over the network using the identifier if the network access device is unable to communicate over the network while operating pursuant to the operational configuration.

13. A communication system, comprising:

a communication network;

a network access device communicatively coupled to the communication network; and

a configuration manager located remotely from the network access device, the configuration manager configured to provision the network access device during a communication session with the network access device over the communication network thereby establishing an operational configuration for the network access device,

wherein the network access device comprises a timer, the timer configured to cause the network access device to automatically implement a predefined configuration if a specified time period expires before the timer is deactivated, the specified time period including a sufficient amount of time, subsequent to the communication session, for enabling a remote device to contact the network access device and to cause deactivation of the timer, wherein the remote device is configured to contact the network access device over the network to deactivate the timer.

14. The system of claim 13, wherein the network access device is configured to communicate with the configuration manager during the communication session pursuant to the predefined configuration.

15. The system of claim 13, wherein the time period is specified by the configuration manager.

16. The system of claim 13, wherein the configuration manager is configured to activate the timer during the communication session.

17. A network access device, comprising:

memory for storing a set of operational control settings and a set of default control settings for the network access device; and

logic configured to store, in the memory, the operational control settings based on data received from a remote device via a wide area network (WAN), the logic configured to control the network access device based on the operational control settings during a specified time period while the network access device is attempting to communicate over the WAN, the logic further configured to begin controlling the network access device based on the default control settings in lieu of the operational control settings in response to a determination that the specified time period expired without the network access device receiving, from the WAN, an indication that communication with the WAN is enabled during the specified time period when the logic is controlling the network access device based on the operational control settings.

18. The device of claim 17, wherein the logic is configured to control the network access device based on the default control settings while the network access device is receiving the data from the network.
