Bit 11: T3 Framing Format Mismatch (T3FM) – This bit indicates the DS3 framer is programmed for a framing
format (C-bit or M23) that is different than the format indicated by the incoming DS3 signal.
Bit 10: Application Identification Channel (AIC) – This bit indicates the current state of the Application
Identification Channel (AIC) from the C11 bit. AIC = 1 is C-bit mode, AIC = 0 is M23 mode.
Bit 9: DS3 Idle Signal (IDLE) – When 0, the receive frame processor is not in a DS3 idle signal (Idle) condition.
When 1, the receive frame processor is in an Idle condition.
Bit 8: Receive Unframed All 1’s (RUA1) – When 0, the receive frame processor is not in a receive unframed all
1’s (RUA1) condition. When 1, the receive frame processor is in an RUA1 condition.
Bit 7: Out Of Multiframe (OOMF) – When 0, the receive frame processor is not in an out of multiframe (OOMF)
condition. When 1, the receive frame processor is in an OOMF condition.
Bit 6: Severely Errored Frame (SEF) – When 0, the receive frame processor is not in a severely errored frame
(SEF) condition. When 1, the receive frame processor is in an SEF condition.
Bit 4: Loss Of Frame (LOF) – When 0, the receive framer is not in a loss of frame (LOF) condition. When 1, the
receive frame processor is in an LOF condition.
Bit 3: Remote Defect Indication (RDI) – This bit indicates the current state of the remote defect indication (RDI)
Bit 2: Alarm Indication Signal (AIS) – When 0, the receive frame processor is not in an alarm indication signal
(AIS) condition. When 1, the receive frame processor is in an AIS condition.
Bit 1: Out Of Frame (OOF) – When 0, the receive framer 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 framer is not in a loss of signal (LOS) condition. When 1, the
receive framer is in an LOS condition.
