Bit 12: Receive Payload Type Unstable (RPTU) – When 0, the receive payload type is stable. When 1, the
receive payload type is unstable.
Bit 11: Receive Payload Type Mismatch (RPTM) – When 0, the receive payload type and expected payload type
match. When 1, the receive payload type and expected payload type do not match.
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 4: Loss Of Frame (LOF) – When 0, the receive frame processor 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 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 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.
Bit 1: Parity Error Count (PEC) – When 0, the parity error count is zero. When 1, the 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.
