Functional Description
Overhead Processor (OHP) Block
Receive OHP (continued)
Table 16 and Table 17 show values of Ns, L, M, and B for STS-3/STM-1, STS-12/STM-4, and STS-48/STM-16 to
set and clear the BER indicator. SF registers are 0x0452—0x0469 and SD registers are 0x043A—0x0451. All
SF/SD set and clear values are hexadecimal.
Table 16. Ns, L, M, and B Values to Set the BER Indicator
* These are the numbers to be provisioned in TDAT042G5. The actual values of the BER algorithm are 1 greater than the actual value s shown.
†
These BER values cannot be provisioned because the maximum value of L is 0xF (i.e., L is a 4-bit register).
