The stat_ts_sync signal is deasserted when a programmed bad_level number of
calendar sequences with frame errors or DIP-2 errors is received without a good
frame. When the stat_ts_sync signal is deasserted, the transmitter stops transmitting
data on the nearest burst unit size boundary or at the next EOP, and starts sending the
training patterns continuously (refer to
Figure 5–6 ).
