LRDIV:
The LRDIV bit is read to determine the remote defect indication state of the RLOP. When
LRDIV is high, the RLOP has declared line RDI.
LAISV:
The LAISV bit is read to determine the line AIS state of the RLOP. When LAISV is high, the
RLOP has declared line AIS.
FEBEWORD:
The FEBEWORD bit controls the accumulation of FEBEs. When FEBEWORD is high, if the
FEBE event has a value from 1 to 4, the FEBE event counter is incremented for each and
every FEBE bit. However, if the FEBE event has a value greater then 4 and is valid, the
FEBE event counter is incremented by 4. When FEBEWORD is low, the FEBE event counter
is incremented for each and every FEBE bit that occurs during that frame (the counter can be
incremented up to 24.).
BIPWORDO:
The BIPWORDO bit controls the indication of B2 errors reported to the TLOP block for
insertion as FEBEs. When BIPWORDO is logic one, the BIP errors are indicated once per
frame whenever one or more B2 bit errors occur during that frame. When BIPWORDO is
logic zero, BIP errors are indicated once for every B2 bit error that occurs during that frame.
The accumulation of B2 error events functions independently and is controlled by the
BIPWORD register bit.
LRDIDET:
The LRDIDET bit determines the line RDI alarm detection algorithm. When LRDIDET is set
to logic one, line RDI is declared when a 110 binary pattern is detected in bits 6, 7 and 8 of
