Description of the problem

Bit Error Rate Calculation Formula

Solution

BER calculation formula:

B1 BER = number of B1 BER blocks / (N x 270 columns x 9 rows x 8bit x 1 second x 8000 frames/second)

Note: N is the N in STM-N

B2 BER = number of B2 BER blocks/{[(261 columns × 9 rows) + (9 columns × 5 rows)] × 8bit × 1 second × 8000 frames/second)}

B3 BER = number of B3 BER blocks / (261 columns × 9 rows × 8 bit × 1 second × 8000 frames / second)
