Bit Name
This bit selects the LOS criteria.
= 0: The G.775 is selected. In short haul application, the LOS is declared when the incoming signal level is less than 800 mVpp for 32 consecutive
bit intervals and is cleared when the incoming signal level is greater than 1 Vpp and has an average mark density of at least 12.5% and less than
16 consecutive zeros in 32 consecutive bit periods. In long haul application, the LOS is declared when the incoming signal level is less than Q dB
below nominal (set in the LOS[4:0] bits (b4~0, E1-029H,...)) for 32 consecutive bit intervals and is cleared when the incoming signal level is greater
than (Q + 4 dB) and has an average mark density of at least 12.5% and less than 16 consecutive zeros in 32 consecutive bit periods.
= 1: The I.431/ETSI is selected. In short haul application, the LOS is declared when the incoming signal level is less than 800 mVpp for 2048
consecutive bit intervals and is cleared when the incoming signal level is greater than 1 Vpp and has an average mark density of at least 12.5%
and less than 16 consecutive zeros in 32 consecutive bit periods. In long haul application, the LOS is declared when the incoming signal level is
less than Q dB below nominal (set in the LOS[4:0] bits (b4~0, E1-029H,...)) for 2048 consecutive bit intervals and is cleared when the incoming
signal level is greater than (Q + 4 dB) and has an average mark density of at least 12.5% and less than 16 consecutive zeros in 32 consecutive bit
periods.
This bit determines whether all ‘One’s can be inserted in the receive path when the LOS is detected.
= 0: Disable the insertion.
= 1: Enable the insertion.
This bit determines whether all ‘One’s can be inserted in the transmit path when the LOS is detected in the receive path.
= 0: Disable the insertion.
= 1: Enable the insertion.
