For short-haul mode, the loss-detection thresholds are based on cable loss of 12dB to 18dB for both T1/J1 and E1
modes. The loss thresholds are selectable based on
is based on cable loss of 30dB to 38dB for T1/J1 and 30dB to 45dB for E1 mode. Note there is no explicit bit called
short-haul mode selection. Loss declaration level is set at 3dB lower than the maximum sensitivity setting
programmed in
The loss state is exited when the receiver detects a certain ones density at the maximum sensitivity level or higher,
which is 3dB higher than the loss-detection level. The loss-detection signal level and loss-reset signal level are
defined with hysteresis to prevent the receiver from bouncing between “LOS” and “no LOS” states.
