TDAT042G5 SONET/SDH
155/622/2488 Mbits/s Data Interface
Functional Description
Overhead Processor (OHP) Block
Receive OHP (continued)
Overhead (OH) Extract. All transport overhead (TOH) bytes are extracted and sent over the RxTOH interface for
possible external processing. The number of bits sent are as follows:

Table 17. 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.
†
58
These BER values cannot be provisioned because the maximum value of L is 0xF (i.e., L is a 4-bit register).
