E3 LOS Condition:
If the level of incoming line signal drops below the threshold as described in the ITU-T G.775 standard, the
LOS condition is detected. Loss of signal is defined as no transitions for 10 to 255 consecutive zeros. No
transitions is defined as a signal level between 15 and 35 dB below the normal. This is illustrated in Figure 9.
The LOS condition is cleared within 10 to 255 UI after restoration of the incoming line signal. Figure 10 shows
the LOS declaration and clearance conditions.
