A 2-wire serial management interface allows the host processor to read and write to the internal registers for configuration, diagnostics, and link status monitoring.

This time-domain reflectometry (TDR)-based tool analyzes the cable plant to detect common wiring faults such as open circuits, short circuits, and impedance mismatches. The distance to the fault is calculated internally and can be read by the host processor via the register map, drastically reducing field maintenance times.
