T1/J1 FER Counter Mapping 0
(02H)
FER[7:0]:
In SF / T1 DM / SLC-96 format, these bits together with the FER[11:8] bits count the F Bit Error numbers. The FER[0] bit is the LSB.
In ESF format, these bits together with the FER[11:8] bits count the Frame Alignment Bit Error numbers. The FER[0] bit is the LSB.
