As defined in ITU-T G.775, an LOS condition is also declared between 10 and 255 UI (or E3 bit periods) after
the actual time the LOS condition has occurred. The LOS condition is cleared within 10 to 255 UI after
restoration of the incoming line signal. Figure 20 shows the LOS declaration and clearance conditions.
