Bit 11: T3 Framing Format Mismatch Latched (T3FML) – This bit is set when the T3FM bit transitions from zero
to one.
Bit 10: Application Identification Channel Change Latched (AICL) – This bit is set when the AIC bit changes
state.
Bit 9: DS3 Idle Signal Change Latched (IDLEL) – This bit is set when the IDLE bit changes state.
Bit 8: Receive Unframed All 1’s Change Latched (RUA1L) – This bit is set when the RUA1 bit changes state.
Bit 7: Out Of MultiFrame Change Latched (OOMFL) – This bit is set when the OOMF bit changes state.
Bit 6: Severely Errored Frame Change Latched (SEFL) – This bit is set when the SEF 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 DS3 frame alignment that is different from the previous DS3 frame alignment.
Bit 4: Loss Of Frame Change Latched (LOFL) – This bit is set when the LOF bit changes state.
Bit 3: Remote Defect 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.
Bit 0: Loss Of Signal Change Latched (LOSL) – This bit is set when the LOS bit changes state.

Bit 11: C-bit Parity Error Latched (CPEL) – This bit is set when a C-bit parity error is detected. This bit is set to
zero in M23 DS3 mode.
Bit 10: Remote Error Indication Latched (FBEL) – This bit is set when a far-end block error is detected. This bit
is set to zero in M23 DS3 mode.
Bit 9: P-bit Parity Error Latched (PEL) – This bit is set when a P-bit parity error is detected.
Bit 8: Framing Error Latched (FEL) – This bit is set when a framing error is detected. The type of framing error
event that causes this bit to be set is determined by
T3.RCR .FECC[1:0]
Bit 3: C-bit Parity Error Count Latched (CPECL) – This bit is set when the CPEC bit transitions from zero to one.
This bit is set to zero in M23 DS3 mode.
