Bit 1: Error Count Control (ECC) – When 0, framing errors, BIP-8 parity errors, and REI errors will not be counted
during an OOF condition (BIP-8 parity error counting will resume in the second full frame after an OOF condition is
cleared). When 1, framing errors, BIP-8 parity errors, and REI errors will be counted during an OOF condition.
Bit 0: Force Framer Re-synchronization (FRSYNC) – A 0 to 1 transition forces the framer into the “Search state.
Once the framer acquires lock, the data path frame counters will be updated regardless of whether an OOF
condition exists or not. The bit must be cleared and set to one again to force another re-synchronization

Bit 8: Loss Of Frame (LOF) – When 0, the receive line interface is not in a loss of frame (LOF) condition. When 1,
the receive line interface is in an LOF condition.
Bit 5: Remote Error Indication Count (REIC) – When 0, the remote error indication count is zero. When 1, the
remote error indication count is one or more.
Bit 4: Parity Error Count (PEC) – When 0, the parity error count is zero. When 1, the parity error count is one or
more.
Bit 3: Framing Error Count (FEC) – When 0, the framing error count is zero. When 1, the framing error count is
one or more.
Bit 2: Remote Alarm Indication (RAI) – This bit indicates the current state of the remote alarm indication (RAI),
which is the fifth bit of the G1 byte (G1[5]).
Bit 0: 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.
