Physical Interface - Electrical
Note: The following settings are available with electrical signal and their
availability depend on the signal itself and its mapping. For optical
interface, see Physical Interface - Optical on page 161.
LBO (Line Build Out): The LBO allows meeting the interface
requirements over the full range of cable lengths.
