Field Description
RES Reserved bits.
Must be set to zero.
L Local loss of sync failure.
This bit is set by CPU software (Port[n]_cfg_reg.Loss) for p
ackets transmitted out the Ethernet port. A
set L bit indicates that the source has detected or has been informed of a TDM physical layer fault
impacting the data to be transmitted. This bit can be used to indicate physical layer LOS that should
trigger AIS generation at the far end. Once set, if the TDM fault is rectified, the L bit must be cleared.
R Remote receive failure.
This bit is set by CPU software (Tx_R_bit fiel
d in bundle configuration) for packets transmitted out the
Ethernet port.. A set R bit indicates that the source is not receiving packets at the Ethernet port, i.e.,
