Abstract

Transmitting a pre-recorded announcement to the user of an network interface unit (NIU) each time the user places a telephone call if an alarm is set because a battery in an uninterruptible power supply (UPS) is in a low power state. The pre-recorded announcement states that the battery needs to be replaced. The user is given a simple procedure for contacting service personnel at a service center to have the battery replaced in the UPS. In addition, this announcement is overridden if the user starts to dial the emergency telephone number (911). This allows the user to gain immediate access to the emergency telephone number without having to listen to the message stating that the battery in the UPS needs to be replaced. An indicator is also set on NIU upon the battery being in the low power state. If a call is completed to the service center, the alarm is reset for a predetermined amount of time to give the service personnel time to service the battery.

Claims

1. A method providing of a battery alarm for a battery in an uninterruptible power supply of a local control unit providing service for a telephone, comprising the steps of:

generating an alarm when the battery is in a low power state by a battery detector in the local control unit;

determining that the battery is in the low power state by a presence of the alarm;

detecting a call origination by the telephone;

transmitting a voice message to the telephone in response to a call origination upon the call origination being for a non-emergency call where the voice message informs the user that the battery is in the low power state before allowing user to continue with the call origination;

providing a user of the telephone abbreviated dialing to originate another telephone call to a service center for the local control unit; and

resetting the alarm for a predetermined amount of time upon the other telephone call being completed to the service center.

2. The method of claim 1 wherein the step of determining comprises the step of setting an indicator on the local control unit upon the alarm being presence.

3. The method of claim 1 wherein the step of generating comprises the step of setting the alarm in response to elapse of the predetermined amount of time and the battery being in a low power state by the battery detector.

4. The method of claim 3 wherein the step of transmitting comprises the step of completing the telephone call without the transmitting the voice message upon telephone call being an emergency call.

5. The method of claim 4 wherein the local control unit is a network interface unit connected to a broadband cable.

6. The method of claim 4 wherein the local control unit is a fixed wireless controller.

7. An apparatus for performing the method of claim 1.

8. An apparatus for performing the method of claim 2.

9. An apparatus for performing the method of claim 3.

10. An apparatus for performing the method of claim 4.

11. An apparatus for performing the method of claim 5.

12. An apparatus for performing the method of claim 6.
