What is the BER value in PTP 670 equipment?, FEC counters per modem ?
BER means Bit Error Ratio.
It describes the quality of the transmission (how many errors in n transmitted bytes), 1x10^-6=1/1 000 000 => there is average 1bit error in every 1 000 000 transmitted bits. Carrier quality starts from 1x10^-6
