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: Receive A Bit (RAB) – This bit is the integrated A bit extracted from the E3 frame.
Bit 6: Receive N Bit (RNB) – This bit is the integrated N bit extracted from the E3 frame.
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 Alarm Indication (RDI) – This bit indicates the current state of the remote alarm 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.
