V7122 Gateway User Guide 359CHAPTER 14: DIAGNOSTICSSeveral diagnostic tools are provided, enabling you to identify correct functioning of thegateway, or an error condition with a probable cause and a solution or workaround. Front panel indicator LEDs on the gateway. The location and functionality of the frontpanel LEDs is shown in TP-1610 Front Panel LED Indicators. Gateway Self-Testing on hardware initialization (see Self-Testing). Syslog Event Notification Messages (see Syslog Support).Self-TestingThe gateway’s self-testing capabilities are used to identify faulty hardware components onstartup and during run time.The gateway features three types of testing modes: Startup tests (Rapid and Enhanced): These tests have minor impact in real-time.While the Startup tests are executed the regular operation of the gateway is disabled. Rapid: The Rapid test is performed every time the gateway starts up. It is executedeach time the gateway completes its initialization process. This is a short test phasein which the only error detected and reported is failure in initializing hardwarecomponents. If an error is detected, an error message is sent to the Syslog. Enhanced: The Enhanced test is performed every time the gateway starts up. Thefollowing hardware components are tested: TSA (Time Slot Assigner). PSTN framers (when they are used). Missing DSP’s. Conference channels (where they are supported).If an error is detected, an error message is sent to the Syslog. Note that when theDetailed test is enabled, errors sent to the Syslog server must be ignored. User-initiated test (Detailed):The Detailed test is initiated by the user when thegateway is offline (isn’t used for regular service).Used in addition to the Rapid and Enhanced test modes. The test is performed onstartup, when initialization of the gateway is completed and if the parameterEnableDiagnostics is set to 1 or 2. In this mode, the gateway tests its DSPs, RAM andflash memory. When EnableDiagnostics is set to 1, flash is tested thoroughly, when
