DASL receiver is synchronized and ready to receive data. It is read by
the microprocessor to assert APA @08 bit 19 to inform the switch that
the adapter is synchronized and it can stop the transmission of the syn-
chronization packets. Remains ‘ON’ if nothing abnormal occurs.

No buffer overrun (normal operation)
1. I = an interrupt is raised because of error or status change.
2. S = status and is reported through polling.
3. In case of buffer overrun all packets are discarded.
