3-CHANNEL DS3/E3/STS-1 TO STS-3/STM-1 MAPPER IC DATA SHEET
As long as the Receive STS-3 TOH Processor block does not detect the “SD Defect Declare B2 byte error-
threshold” number of B2 byte errors, within this “SD Defect Declare Monitor” time period, then it will not
declare the SD Defect Condition. Conversely, if the Receive STS-3 TOH Processor block detects at least the
“SD Defect Declare B2 error threshold” number of B2 byte errors, within the “SD Defect Declare Monitor time
period, then it will declare the SD Defect Condition.
Figure 89 presents an illustration of the SD Detector accumulating B2 Byte errors over a “monitoring” time
period.

“Monitoring” Time period

The user can specify the “SD Defect Declare B2 Byte Error Threshold” by writing the appropriate value into
the “Receive STS-3 Transport – Receive SD Set Threshold – Byte 1 and Byte 0” registers, as depicted below.
Receive STS-3 Transport – Receive SD SET Threshold – Byte 1 (Address = 0x1142)
Receive STS-3 Transport – Receive SD SET Threshold – Byte 0 (Address = 0x1143)
Notes:
The “Receive STS-3 Transport – Receive SD SET Threshold – Byte 1 and Byte 0” Registers permits the user to write in a
The “default” value for the “B2 Byte Error Threshold” is 0xFFFF.
S
Likewise, the user can specify the length of the “SD Defect Declare Monitor Time” period by writing the
appropriate value into the “Receive STS-3 Transport – Receive SD Set Monitor Interval – Byte 2, 1 and 0”
registers, as depicted below.
