Figure 6.5 shows how the data are organized for the transmission. Each data frame
includes two data fields, each with 313 data segments. The first segment of each data field
is a synchronizing signal, which includes a training sequence used by the equalizer in the
receiver. The remaining 312 data segments transport the data equivalent to the transport
of 188 bytes, as well as the overload associated with the FEC. These 828 symbols a
