CCNet note processing
Fault Events
There is no specific self test command with CCNet, the acceptor reports faults in response to a poll.
When the protocol handler completes its initialisation, the first idle response is reported as
IMHEI_NOTE_NOW_OK.
When a FAILURE response to a status poll is received, this is reported as an
IMHEI_NOTE_UNIT_REPORTED_FAULT event. A failure status is expected to be continually reported by
the acceptor until it is cleared. When the acceptor again reports IDLING, then an IMHEI_NOTE_NOW_OK
event is reported.
Other “non normal” responses to a status poll are reported as events as they are receive according to
the table below.
In a similar way to the action for faults, OUTPUT_FIXED is reported when events that translate to
OUTPUT_PROBLEM are cleared.
Most status values are part of the normal running of the system, the following statuses are regardless
as reporting unusual / fault events and are reported through the event system.
Generate an OK_NOW or OUTPUT_FIXED
if in fault / output problem.
