Abstract
The present invention enables the self-diagnosis functionality by embedding a cable modem with the CMTS system with mechanisms to redirect the signals from external connections to the embedded cable modem, thereby enabling the end user to fully test the CMTS using a suite of diagnostic tests. The embedded cable modem integrates the external CM, computer and diagnostic software in the chassis, or alternatively onto the CMTS card in the chassis. The invention enables the end user to fully test the functionality as a stand-alone unit, without relying on any external test equipment or methods. It also enables the end user to diagnose the CMTS from a remote location. Another major advantage of the present invention is that it enables the CMTS/CM function to be verified over the entire physical layer parameter set (frequency, symbol rate, FEC, signal levels, etc.) while not interrupting any of the services that are on the ‘live’ HFC plant.
