Patent ID: 7116637

Claim:
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.
