Abstract:
A method and apparatus for detecting and locating a fault in a cable network. A cable modem may perform channel estimation to obtain a time domain channel response on an echo channel in a cable network. The cable modem then analyzes the time domain channel response to determine whether there is any change from a previously obtained time domain channel response on the echo channel. If there is a change from the previously obtained time domain channel response, the cable modem may generate an alert for a fault in the cable network and estimate a location of the fault based on the time domain channel response. Calibration may be performed to determine a reference latency for a reflection occurred inside the cable modem, and the location of the fault may be estimated based on the reference latency.

Claim (Index 10):
A method for detecting and locating a fault in a cable network, the method comprising:\n performing channel estimation to obtain a time domain channel response on an echo channel; analyzing the time domain channel response to determine whether there is any change in the echo channel; and estimating a location of a fault in the cable network based on the time domain channel response if it is determined that there is a change in the echo channel.
