BBD0/1 Detected
These signals are set if either ’1' (BBD1) or ’0' (BBD0) were detected in
4 subsequent basic frames. It is used as a criterion that the receiver has
acquired frame synchronization and both its EC- and EQ-coefficients
have converged. BBD0 corresponds to the received signal SL2 in case
of a normal activation, BBD1 corresponds to the internally received
signal SN3 in case of analog loop back.
Awake tone detected
The U-transceiver is requested to start an activation procedure.
