3-CHANNEL DS3/E3/STS-1 TO STS-3/STM-1 MAPPER IC DATA SHEET
S
Likewise, the user can specify the “SF Clear Interval” period by writing the appropriate value into the “Receive
STS-3 Transport – Receive SF Clear Monitor Interval – Byte 2, 1 and 0” registers, as depicted below.
Receive STS-3 Transport – Receive SF Clear Monitor Interval – Byte 2 (Address = 0x115D)
Receive STS-3 Transport – Receive SF Clear Monitor Interval – Byte 1 (Address = 0x115E)
Receive STS-3 Transport – Receive SF Clear Monitor Interval – Byte 0 (Address = 0x115F)
Notes:
The “Receive STS-3 Transport – Receive SF Clear Monitor Interval – Byte 2, Byte 1 and Byte 0” registers permit the user
The actual length of time that the Receive STS-3 TOH Processor block will use (to accumulate B2 errors) to declare the
Examples of Defining the SF Clearance Criteria – per the “SF Burst” Detector
Suppose that the user writes in the value “0x0008” into the “Receive STS-3c Transport – Receive SF Burst
Error Tolerance” Registers; as depicted below.
Receive STS-3 Transport – Receive SF Burst Error Tolerance – Byte 1 (Address = 0x1156)
Receive STS-3 Transport – Receive SF Burst Error Tolerance – Byte 0 (Address = 0x1157)

to write in a 24-bit expression for the “SF Clear Interval”. The number that is written into these registers represents
the duration of the “SD Clear Interval” periods, in terms of SONET frame periods.
SF condition is the value written into these registers.
