LRDIDET:
The LRDIDET bit determines the Line LRDI detection algorithm. When LRDIDET is set to logic one, Line LRDI 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 set to logic zero, Line LRDI is declared when a 110 binary pattern is detected in bits 6,7 and 8 of the K2 byte for five consecutive frames.
AISDET:
The AISDET bit determines the Line AIS detection algorithm. When AISDET is set to logic one, Line AIS is declared when a 111 binary pattern is detected in bits 6,7 and 8 of the K2 byte for three consecutive frames. When AISDET is set to logic zero, Line AIS is declared when a 111 binary pattern is detected in bits 6,7 and 8 of the K2 byte for five consecutive frames.
ALLONES:
The ALLONES bit controls automatically forcing the SONET frame passed to downstream blocks to logical
BIPWORD:
The BIPWORD bit controls the accumulation of B2 errors. When BIPWORD is logic one, the B2 error event counter is incremented only once per frame whenever one or more B2 bit errors occur during that frame. When BIPWORD is logic zero, the B2 error event counter is incremented for each B2 bit error that occurs during that frame (the counter can be incremented up to 24 times per frame).
Reserved:
The reserved bits must be programmed to logic zero for proper operation.
