352 V6100 and V7122 User Guide Periodic – (doesn’t apply to the V6100) The Periodic Test is performed every hour afterstartup, even when there is full traffic on the V7122; quality is not degraded. Thefollowing hardware components are being tested:a) TSA.b) PSTN framers (when they are used).c) Missing DSP’s.d) Conference channels (where they are supported).e) If an error is detected, an error message is sent to the Syslog. Detailed - Used in addition to the Rapid and Enhanced test modes. The test is performedon startup, when initialization of the V7122 is completed and if the parameterEnableDiagnostics is set to 1 or 2. In this mode, the V7122 tests its DSPs, RAM andflash memory. When EnableDiagnostics is set to 1, flash is tested thoroughly, whenEnableDiagnostics is set to 2, flash is only partially tested. While the Detailed test isrunning, the Orange LED (of the orgy LEDs) is lit.If an error is detected, an error message is sent to the Syslog.CAUTION:To continue regular operation the Detailed test must be disabled. Set theparameter EnableDiagnostics to 0 and reset the V7122.Syslog SupportSyslog protocol is an event notification protocol that enables a machine to send eventnotification messages across IP networks to event message collectors- also known asSyslog servers. Syslog protocol is defined in the IETF RFC 3164 standard.Since each process, application and operating system was written independently, there islittle uniformity to Syslog messages. For this reason, no assumption is made on the contentsof the messages other than the minimum requirements of its priority.Syslog uses UDP as its underlying transport layer mechanism. The UDP port that wasassigned to Syslog is 514The Syslog message is transmitted as an ASCII (American Standard Code for InformationInterchange) message. The message starts with a leading ‘<’ ('less-than' character), followedby a number, which is followed by a ‘>’ ('greater-than' character). This is optionally followedby a single ASCII space.The number described above is known as the Priority and represents both the Facility andSeverity as described below. The Priority number consists of one, two, or three decimalintegers.
