Abstract
Various embodiments relate to detecting a cable fault within a network. A method may include transmitting a pulse signal to a cable of a shared bus from a node, and observing a signal received at the node in response to the pulse signal. The method may also include determining a fault condition of the cable based on the pulse signal and on an amplitude of each sample of a number of samples of the one or more observed signals.

(canceled)
A method, comprising:
- transmitting one or more pulse signals from a node to a cable of a shared bus;
- sampling one or more signals received at the node in response to the one or more pulse signals;
- and
- determining a fault condition of the cable based on the one or more pulse signals and a number of samples of the one or more signals.

A method, comprising:
- transmitting a pulse signal from a node to a cable of a shared bus of a network;
- observing a signal received at the node in response to the pulse signal;
- and
- determining a fault condition of the cable based on the observed signal.
1 more element
A device, comprising:
- a transmitter configured to transmit at least one pulse signal to a cable of a shared bus;
- a receiver configured to observe at least one second signal received in response to the at least one pulse signal;
- and
- circuitry configured to:
- compare an amplitude of each sample of the at least one second signal to at least one threshold value;
- and
- generate a detector output signal for each sample of the at least one second signal based on the comparison of the amplitude of each sample of the at least one second signal to the at least one threshold value;
- and
- receive the detector output signal for each sample of the at least one second signal;
- and
- determine a fault condition of the cable based on the at least one pulse signal and an amplitude of each sample of a number of the samples of the at least one second signal.
