iagnostics/ 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. 3.78
System Self-Diagnostics .SYSTEM IMPLEMENTS THE FOLLOWING TESTS WHEN THE SYSTEM IS POWERED ON, BY PRESSING THE CPM RESTART BUTTON, OR BY THE WATCH DOG TIMER OVERFLOW:- RAM READ/WRITE TEST - RAM PROTECTION TEST - SWITCH CONTROL TEST - NON-VOLATILE RAM CHECK e TABLE BELOW INDICATES THE TYPE OF ALARM AND SYSTEM RESPONSE TO ERRORS DETECTED DURING SELF- DIAGNOSTIC TESTS: TYPE OF DIAGNOSTICSRAM/R/W TYPE OF RESTART TYPE OF ALARM SYSTEM RESPONSE COLDHOTRRUNTO ALM XXON -ONCALL PROCESSINGUNINTERRUPTED RAM MEMORY X XON -ONCALL PROCESSINGUNINTERRUPTED SWC MEMORY R/W X XXON -ON CALL PROCESSINGUNINTERRUPTED NON-VOLATILE RAM XXXON -OFFINITIATE COLD RESTART (ODDB IS LOST) NOTE:ALL ERRORS/RESPONSES ARE ENTERED IN THE SYSTEM FAULT LOG.

IF THERE HAS BEEN A LONG TERM POWER FAILURE, NO ACTION IS NEEDED. THE BATTERY IS BEING CHARGED. IF DISCHARGE CONDITION CONTINUES MORE THAN TWO DAYS, CHANGE BACK-UP BATTERY. SAVE CUSTOMER DATA BASE TO TAPE.NO RESPONSE IS NEEDED. IF SYSTEM OPERATION DETERIORATES, INITIATE RESTART. (RESET, HOT, OR COLD RESTART).REPLACE WITH SPARE RGEN CARD. 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 CPM OR MEM CARDS. 3.86
