8.11.3.5
For short-haul mode, loss is declared if the received signal level is 3dB lower from the programmed value (based
on
declared at 15dB. LOS is reset if the following criteria are met:
For long-haul mode, loss is detected if the received signal level is 3dB lower from the programmed value (based on
Table
will be 33dB. LOS is reset if the following criteria are met:
8.11.3.6
For short-haul mode, loss is declared if the received signal level is 3dB lower from the programmed value (based
on
declared at 15dB. LOS is reset if the receive signal level is greater than or equal to the programmed sensitivity
level for a duration of 192-bit periods.
For long-haul mode, loss is detected if the received signal level is 3dB lower from the programmed value (based on
Table
will be 33dB. LOS is reset if the receive signal level is greater than or equal to the programmed sensitivity level for
a duration of 192-bit periods.
8.11.3.7
For short-haul mode, loss is declared if the received signal level is 3dB lower from the programmed value (based

or equal to programmed sensitivity level for a duration of 192-bit periods.
For long-haul mode, loss is declared if the received signal level is 3dB lower from the programmed value (based on
Table
equal to the programmed sensitivity level for a duration of 192-bit periods.
