ABSTRACT:
A physical layer (PHY) device including a first transmitter, a first analog-to-digital converter (ADC) module, and a control module. The first transmitter is configured to transmit a first pulse on a first conductor of a first pair of conductors of a cable. The first ADC module is configured to generate a first set of outputs, in response to the transmission of the first pulse, by sampling an input from a second conductor of the first pair of conductors a plurality of times at a predetermined time interval. The control module is configured to determine a first distance from the PHY device to (i) an open-circuit, (ii) a short-circuit, or (iii) a termination of the first pair of conductors based on the first set of outputs.
