The general criterion applied for the I/P bus failure detection is the following: for a given bus, if any of the labels constantly monitored by the DMC for checking of the bus validity is seen in the INVALID condition (i.e.: |no refresh| or|SSM in the F/W state| or|SSM in the F.T. state in flight|), the bus is considered faulty for the BITE, provided that the failure is present for 1,5s min.
NOTE : After each DMC reset, the monitoring of external failures is
____ inhibited for 20s. The failure criteria for all the DMC I/P buses are: IRSX: general criterion (X = 1, 2 or 3) ADCX: general criterion (X = 1, 2 or 3) FACX: general criterion or bad FAC healthy discrete signal (X = 1 or 2) FMGCX-EFIS : bad FMGC healthy discrete signal (X = 1 or 2) FCU-X: general criterion (X = A or B) FMGCX-A : general criterion (X = 1 or 2)
VORX, DMEX, ILSX, R/AX, ADFX : general criterion (X = 1 or 2)

(10) SWITCHING TEST The reconfiguration devices are tested and the switching stages inside the DMC and DU (Ref. Fig. 023) Display (A)
This is the step INITIAL CONDITIONS where the operator is asked to
set the two related selector switch to NORM.
Display (B)
This is the step 1 where the operator is asked to check that colour
messages displayed on the DUs are in agreement with the ones listed
on the MCDU.

This is the step 2 = after the selector switch has been set to CAPT
the operator is asked to check that the messages displayed on the DUs
are in agreement with the ones mentionned.

This is the step 3 = after the selector switch has been set to FO the
operator is asked to check that the messages displayed on the DUs are
in agreement with the ones mentionned.

This is the step 3 for the DMC1: the operator is asked to check that
the messages on the DUs are in agreement with the ones mentionned.
