Register Descriptions
OHP Registers
Table 87. Ns, L, M, and B Values to Clear 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 values shown.
†
188
These BER values cannot be provisioned because the maximum value of L is 0xF (i.e., L is a 4-bit register).
