CNTDK1K2FRAME[3:0]
Continuous N Times Detect for APS Frame Bytes.
Sets the number of CNTD frames within which an
inconsistent APS value is detected in the incoming
STS-3/STM-1 (AU-4). This value is used in the APS
Babble algorithm. The valid range for this register is
0x3—0xF. Invalid values will be mapped to a value of
0x3.
Continuous N Times Detect for APS (K1, K2[7:3])
Bytes.
Sets the number of CNTD occurrences of a con-
sistent APS value in the incoming STS-3/STM-1 (AU-4)
frame. The valid range for this register is 0x3—0xF.
Invalid values will be mapped to a value of 0x3.
Continuous N Times Detect for F1 Byte.
Sets the
number of CNTD occurrences of a consistent F1 value
in the incoming STS-3/STM-1 (AU-4) frame. The valid
range for this register is 0x3—0xF. Invalid values will be
mapped to a value of 0x3.
Continuous N Times Detect for J0 Byte.
Sets the
number of CNTD occurrences of a consistent J0 value
in the incoming STS-3/STM-1 (AU-4) frame. The valid
range for this register is 0x3—0xF. Invalid values will be
mapped to a value of 0x3.
Reserved.
Continuous N Times Detect for Loss of Pointer
State.
Control bits are the number of consecutive con-
ditions for invalid pointer and invalid concatenation indi-
cation (pointer interpretation). Valid values are the
following: 00 = 8, 01 = 9, 10 = 10, and 11 = 8.
Continuous N Times Detect for S1 Frame Bytes.
Sets the number of CNTD frames within which an
inconsistent S1 value is detected in the incoming STS-
3/STM-1 (AU-4). This value is used in the S1 babble
algorithm. The valid range for this register is 0x3—0xF.
Invalid values will be mapped to a value of 0x3.
Continuous N Times Detect for S1 Byte.
Sets the
number of CNTD occurrences of a consistent S1 value
in the incoming STS-3/STM-1 (AU-4) frame. The valid
range for this register is 0x3—0xF. Invalid values will be
mapped to a value of 0x3.
Continuous N Times Detect for K2[2:0] Byte.
Sets
the number of CNTD occurrences of a consistent
K2[2:0] value in the incoming STS-3/STM-1 (AU-4)
frame. The valid range for this register is 0x3—0xF.
Invalid values will be mapped to a value of 0x3.
