SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
(3) For Level I codes identified as not applicable in the tables, the SDU does not report
the failure on that particular interface (i.e., CFDS normal and interactive modes or
SCDU accessed maintenance pages as appropriate). Where TBD is used in the
Level I failure message column, it is coded as literally read. For failures that occur
that are undefined in the tables, the SDU does not report the failure on that particular
interface.
