Troubleshooting Overview . TROUBLESHOOTING IS A SYSTEMATIC APPROACH TO IDENTIFYING AND ISOLATING SYSTEM PROBLEMS. . PRIMARY TROUBLESHOOTING TOOLS INCLUDE BOTH THE DEVICE STATUS AND FAULT LOG TABLES, IN CONJUNCTION WITH SYSTEM VISUAL INDICATORS. l ISOLATION OF A PROBLEM’S CAUSES REQUIRES: 1. DETERMINATION OF SPECIFIC PROBLEMS (E.G., NO RINGING, NO DIAL TONE) 2. DETERMINATION OF THE EXTENT OF THE PROBLEM (E.G., A CIRCUIT, A CARD, OR A GROUP NUMBER) . CORRECTION OF A PROBLEM REQUIRES: 1. INITIAL CHECKING OF CORRECT SYSTEM OPERATION. 2. POSSIBLE REPLACEMENT OF DEFECTIVE COMPONENTS OR RELATED FOLLOW- UP ACTION. 3. TESTING TO ENSURE CORRECT MAINTENANCE SYSTEM OPERATION. 3.46
ICGO 1 1 t 2 1 3 1 4 1 @ A SYSTEM-WIDE PROBLEM lS INDICATED BY A COMPLETE CALL PROCESSlNG FAILURE. . SYSTEM-WIDE PROBLEMS USUALLY ARE CAUSED BY: - A DEFECTIVE POWER SUPPLY OR FAULT IN THE INTERCONNECTING POWER CABLES, OR - A DEFECTIVE COMMON CONTROL GROUP CARD. . IF CAUSE CANNOT BE ISOLATED, THE CABINET BACKPLANE CIRCUITRY MAY BE DEFECTIVE. 0 REFER TO THE FOLLOWING THREE FLOWCHARTS FOR TROUBLESHOOTING PROCEDURES FOR SYSTEM-WIDE PROBLEMS. 3.47
