appropriate subtest depending on options fitted. Test are run as follows.
 CPU test
       CONFIDENCE test
       PDH test
       BER test (Note does not perform DCC port test)
       JITTER test
See Tables for each of these tests for a list of the subtests and Figure 5-1for the
loopback cabling required for this test. Note a Formatted floppy disk is required as
