____
the REQUEST indication is again available.
1_ REQUEST VHF3 LINK (1L)
This line key enables to activate the VHF link test and to
display the status of the connection between the VDR3 and the
ground.
2_ REQUEST SAT LINK (1R) (if SATCOM system is installed)
This line key enables to activate the Satcom link test and to
display the status of the connection between the SDU1 and the
ground.
3_ REQUEST HF LINK (3R) (if HFDR system is installed)
This line key enables to activate the HF link test and to
display the status of the connection between the HFDR and the
ground.

(c) AUDIT page AUDIT page enables automatic printing of all downlink and/or uplink datalink messages that transit through the ATSU. By default, the AUDIT mode is deactivated (all toggles set to NO). Specific communication means can be audited separately:
-VHF3
-SATCOM (if installed)
-HF (if installed)
-UPLINKS
-DOWNLINKS.
The AUDIT function consists in collecting the content of all or
some ARINC 618 blocks exchanged by the router with the ground and
in printing them out with a predefined format.
This function can be deactivated from this page or from the COMM
MENU page.
