LRDIV

LRDIV:

The LRDIV bit is read to determine the remote defect indication state. When

LRDIV is a logic one, the S/UNI-PLUS has declared line RDI.

LAISV:

The LAISV bit is read to determine the line AIS state. When LAISV is a logic

one, the S/UNI-PLUS has declared line AIS.

FEBEGEN:

The FEBEGEN bit controls the indication of B2 errors reported to the TLOP

block for insertion as FEBEs. When FEBEGEN is a logic one, a single FEBE

is indicated each frame whenever one or more B2 errors occur during that

frame. When FEBEGEN is a logic zero, a single FEBE is indicated for each

B2 bit error that occurs during that frame (maximum of 24 FEBEs per frame

for STS-3c/STM-1). 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 a logic one, line RDI is declared when a 110 binary pattern is

detected in bits 6, 7, and 8 of the K2 byte for three consecutive frames. When

LRDIDET is a logic zero, line RDI is declared when a 110 binary pattern is

detected in bits 6, 7, and 8 of the K2 byte for five consecutive frames.
