Bit 1: Out Of Frame (OOF) – When 0, the receive frame processor is not in an out of frame (OOF) condition.
When 1, the receive frame processor is in an OOF condition.
Bit 0: Loss Of Signal (LOS) – When 0, the receive loss of signal (LOS) input (RLOS) is low. When 1, RLOS is
high.

Bit 8: Receive Unframed All 1’s Change Latched (RUA1L) – This bit is set when the RUA1 bit changes state.
Bit 7: A Bit Change Latched (ACL) – This bit is set when the RAB bit changes state.
Bit 6: N Bit Change Latched (NCL) – This bit is set when the RNB bit changes state.
Bit 5: Change Of Frame Alignment Latched (COFAL) – This bit is set when the data path frame counters are
updated with a new frame alignment that is different from the previous frame alignment.
Bit 4: Loss Of Frame Change Latched (LOFL) – This bit is set when the LOF bit changes state.
Bit 3: Remote Alarm Indication Change Latched (RDIL) – This bit is set when the RDI bit changes state.
Bit 2: Alarm Indication Signal Change Latched (AISL) – This bit is set when the AIS bit changes state.
Bit 1: Out Of Frame Change Latched (OOFL) – This bit is set when the OOF bit changes state.
