Abstract

A method for diagnosing Voice-over-Broadband circuitry including an Integrated Access Device. The method includes receiving a request to initiate diagnosis, pulsing source voltages of tip and ring amplifiers in the circuitry, aggregating signal line noise resulting from the pulsing, analyzing the aggregated noise for hallmark indicia, and reporting findings of the analysis.

Claims

1. A system for remotely diagnosing voice over broadband circuitry, comprising:

a broadband line; and

an integrated access device coupled to the broadband line, the integrated access device comprising;

a microprocessor controller coupled to the broadband line;

a CODEC connected to the microprocessor controller;

a subscriber line interface circuit coupled to the CODEC, the subscriber line interface circuit comprising;

tip and ring amplifiers; and

a switching circuit for pulsing source voltage of the tip and ring amplifiers;

a primary battery supply and an auxiliary battery supply coupled to the subscriber line interface circuit;

a POTS port coupled to the subscriber line interface circuit and providing a coupling to a POTS device; and

a signal line, configured to interconnect the broadband line, microprocessor controller, CODEC, subscriber line interface circuit, and POTS port;

wherein the microprocessor controller is configured to execute a software algorithm configured to control the switching circuit into pulsing source voltage of the tip and ring amplifiers in predetermined patterns that will cause noise in the signal line that may be used to determine a status of the integrated access device.

2. The system of claim 1, wherein the software algorithm is further configured to pulse the tip and ring amplifiers'"'"' source voltage from a forward disconnect state to a VBAT2 state in a frequency sweep mode.

3. The system of claim 1, wherein the software algorithm is further configured to pulse the tip and ring amplifiers'"'"' source voltage from a VBAT2 state to a VBAT1 state in a fixed frequency mode.

4. The system of claim 1, wherein the microprocessor controller is configured to commence execution of the software algorithm in accordance with a programming logic instruction internal to the integrated access device.

5. The system of claim 1, wherein the microprocessor controller is configured to commence execution of the software algorithm in accordance with an instruction received via a broadband line from a source external to the integrated access device.

6. The system of claim 1, wherein the microprocessor controller is configured to commence execution of the software algorithm in accordance with an instruction received via an RS-232 port from a source external to the integrated access device.
