Abstract

A method uses circuitry in a data interface that provides telephony service over a high-speed network to detect the presence of a secondary source of VBH battery voltage on a tip-ring system. If a detected source other than the data interface is impressing battery voltage on the tip-ring system, the circuitry disconnects the data interface's battery source and produces a message that another source is VBH. The determination that another source is present may be based on a threshold value to account for noise. The message is used to produce an alarm at a user interface device. The alarm may be a light indication mounted on the data interface. The alarm may also be a web page that is retrieved from a memory device and displayed on a PC, a PDA or the data interface. The alarm may be provided locally and remotely to a provider's server.

Claims (10)

1. A method for providing an alarm that more than one source is impressing a battery voltage onto a tip-ring pair wiring system when a telephony-over-data network device is used for providing telephony services, comprising:

disconnecting a first supply circuit for providing battery voltage to the tip-ring system, the first supply circuit being associated with the network device;

measuring the voltage on the tip-ring system while the first supply is disconnected from the tip-ring system; and

generating an alarm signal if voltage is detected on the tip-ring system.

2. The method of claim 1 wherein the alarm signal is generated if the measured voltage is above a predetermined threshold.

3. The method of claim 1 further comprising, before disconnecting the first supply from the tip-ring pair, generating an imbalance signal if the voltage on said tip-ring system is not a steady voltage within a predetermined range.

4. The method of claim 1 further comprising indicating on a user interface that an alarm signal has been generated.

5. The method of claim 4 wherein the user interface is an LED.

6. The method of claim 4 wherein the user interface is a web page.

7. The method of claim 4 wherein the user interface is located at a head end.
