Bit 3: C-bit Parity Error Count (CPEC) – When 0, the C-bit parity error count is zero. When 1, the C-bit parity
error count is one or more. This bit is set to zero in M23 DS3 mode.
Bit 2: Remote Error Indication Count (FBEC) – When 0, the remote error indication count is zero. When 1, the
remote error indication count is one or more. This bit is set to zero in M23 DS3 mode.
Bit 1: P-bit Parity Error Count (PEC) – When 0, the P-bit parity error count is zero. When 1, the P-bit parity error
count is one or more.
Bit 0: Framing Error Count (FEC) – When 0, the framing error count is zero. When 1, the framing error count is
one or more. The type of framing error event counted is determined by T3.RCR.FECC[1:0]

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 Multi-frame 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.
