Abstract

A method and apparatus provide for managing operations associated with a backup power source at a network terminal. A network terminal includes a battery port that, when enabled, is configured to monitor status of a battery coupled to the battery port and provide a status indicator for the battery. The network terminal also includes an interface with selectable states. A control circuit detects the state of the interface and presence of a battery at the battery port. In response to the interface being in a given state in an absence of a battery coupled to the battery port, the control circuit causes the battery port to enter or remain in a disabled state. The battery port substantially maintains the disabled state over reset, loss of power and reconfiguration of the network terminal. If the battery port detects the presence of a battery, it responds by entering an enabled state to monitor the status of the battery and provide battery status indicators.

Claims

1. An apparatus for managing operations associated with a backup power source at a network terminal, the apparatus comprising:

a battery port at a network terminal configured, in an enabled state, to monitor status of a battery and provide a status indicator indicating presence or status of the battery;

an interface at the network terminal having selectable states; and

a control circuit coupled to the interface and the battery port and, in response to the interface being in a given state in an absence of the battery coupled to the battery port, the control circuit is configured to disable reporting of information related to the battery and substantially continue to disable the reporting over reset, loss of power or reconfiguration of the network terminal and, in response to detecting presence of a battery at the battery port, the control circuit is further configured to enable the reporting.

2. The apparatus of claim 1 wherein the battery port includes a battery charger and a battery status monitor, the battery status monitor operable to detect presence and power level of a battery and provide alarms in response to detecting one of absence of a battery and low power level of a battery.

3. The apparatus of claim 1, wherein the control circuit is configured to cause the battery port to enter a disabled state in response to the interface being in the given state in the absence of the battery coupled to the battery port.

4. The apparatus of claim 3 wherein the battery port in the disabled state is configured to disable the battery charger and alarms.

5. The apparatus of claim 4 wherein the battery port in the disabled state is configured to detect the presence of a battery.

6. The apparatus of claim 1 wherein the control circuit is configured to refrain from disabling the reporting in response to detecting presence of a battery.

7. The apparatus of claim 1, wherein the user interface is a pushbutton.

8. The apparatus of claim 7, wherein the pushbutton maintains the active state when pushed continuously, and is inactive when not pushed, and wherein the given state is the active state.

9. The apparatus of claim 1, wherein the control circuit is configured to provide an audible indication at least in an event the control circuit disables the reporting.

10. The apparatus of claim 1, further comprising a non-volatile memory to store a configuration associated with the control circuit disabling the reporting.

11. The apparatus of claim 10, wherein the control circuit is configured to modify the configuration in response to detecting a battery at the battery port.

12. A method of managing operations associated with a battery at a network terminal, the method comprising:

monitoring a selectable state of an interface at a network terminal;

determining a presence or absence of a battery at the network terminal;

disabling reporting of information related to the battery, in response to the absence of the battery and the state of the interface, over reset, loss of power or reconfiguration of the network terminal;

monitoring the presence of a battery at the battery port; and

enabling reporting of information related to the battery in response to detecting the presence of a battery at the battery terminal.

13. The method of claim 12 wherein the reporting of information includes reporting at least one of battery status, battery presence and battery power level, the reporting including providing an alarm or message corresponding to the reporting.

14. The method of claim 12 further comprising disabling charging of a battery in response to the absence of the battery and the state of the interface.

15. The method of claim 12 wherein the monitoring is performed during initialization of the network terminal.

16. The method of claim 15 further comprising preventing disabling the reporting in response to detecting presence of a battery during the initialization.

17. The method of claim 12 wherein disabling reporting of information includes determining a state of a pushbutton configured to be the interface.

18. The method of claim 17 wherein the disabling is performed in response to the pushbutton being maintained in an active state in the absence of the battery, the pushbutton being in the active state when pushed.

19. The method of claim 12 further comprising providing an audible indication at least when the disabled state is entered.

20. The method of claim 12 further comprising storing a configuration associated with the a disabled state to a non-volatile memory.

21. The method of claim 20 further comprising modifying the configuration in response to detecting a battery at the battery port.

22. A computer program product having processor-readable instructions stored thereon, the processor-readable instructions, when loaded and executed by a processor, cause the processor to:

monitor a selectable state of an interface at a network terminal;

determine a presence or absence of a battery at the network terminal;

disable reporting of information related to the battery, in response to the absence of the battery and the state of the interface, over reset, loss of power or reconfiguration of the network terminal;

monitor the presence of a battery at the battery port; and

enable reporting of information related to the battery in response to detecting the presence of a battery at the battery terminal.
