							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.

@ 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.
