    eDIAGNOSTICS ARE A GROUP OF SYSTEM FUNCTIONS THAT FACILITATE
    MAINTENANCE BY DETECTION AND ISOLATION OF HARDWARE AND
    SOFTWARE MALFUNCTIONS.
    @OMNI SBCS PROVIDES 3 TYPES OF ON-LINE SYSTEM DIAGNOSTICS:
    -SELF-DIAGNOSTICS: ROUTINE SELF-TESTS DONE AT TIME OF
    A RESTART WHERE SYSTEM RESPONDS TO A DETECTED ERRORWITH AN ALARM.
    -CALL-PROCESSING DIAGNOSTICS: ROUTINE TESTS DONE
    CONTINUOUSLY AND AUTOMATICALLY BY OPERATING SYSTEM.
    -MANUAL Tl?UNK CONNECTION DIAGNOSTICS: CMCCOMMAND DEDICATED TO TESTING TRUNKS WHILE SYSTEM IS
    ON-LINE.

    BUTTON, OR BY THE WATCH DOG TIMER OVERFLOW:- RAM READ/WRITE TEST
    - RAM PROTECTION TEST

    NOTE:IF FAULT LOG CANNOT BE ACCESSED, REPLACE CPM CARD. INITIATE RESET AND VERIFY SYSTEM OPERATION
    BEFORE CHANGING CPM CARD. ENSURE THAT ODDB HAS BEEN SAVED BEFORE REPLACING
