Managing Multiplexers1-196800-A2-GB21-10 August 1994Alarm Severity Reporting ConfigurationYou can configure ACCULINK multiplexers (except the 741 chassis) so that when they detect aparticular class of node and facility alarms they will activate alarm relays or an audible alarm onthe multiplexers themselves. This feature is not supported by the 741 chassis since it does not havealarm relays.You can configure alarm severity using the Change Node Configuration Parameters (chncp)command. It allows you to activate the priority levels for alarm relays and audible alarms atmultiple nodes in one operation (this is only one of many functions supported by this command).When you execute this command with the Configure Alarm Severity Reporting field set to Yes,a series of input forms display, some of which are for alarm severity reporting for classes of facilityand node alarms. On these forms you can specify the alarm relays and audible alarm parameters.You can also activate the severity levels for audible alarm or alarm relays for one node at a time. Ifyou specify a 740-chassis node, you can designate the alarm relay or audible alarm that is activatedwhen an alarm occurs on an aggregate link, a DS1 channel interface module, a control processormodule, etc. If you specify a 745 node, you can designate the alarm relay or audible alarm that isactivated when an alarm occurs on a T1 link, a control processor, a TSI clock, etc.Using this command, each alarm class can be assigned one, a combination, or none of thefollowing alarm signals.audibleA tone generator beeps in the multiplexer when an alarm is active.majorThe alarm activates the major alarm LED on the power shelf front bezel and the majoralarm relay.minorThe alarm activates the minor alarm LED on the power shelf front bezel and the minoralarm relay.noneThe alarm does not activate any LEDs or alarm relays.If you want to check which classes of node and facility alarms are configured to activate alarmrelays and audible alarms, execute the Display Node Configuration Parameters (dsncp) commandwith the Configure Alarm Severity Reporting field set to Yes.For detailed information on these commands, refer to the COMSPHERE 6800 Series NetworkManagement System Multiplexer Command Reference Manual.Event Reporting ConfigurationEvent log messages are generated by the ACCULINK multiplexers whenever anything of interestoccurs within the node. This can be an alarm or fault condition, or an informational message.There are three event logs (see NOTE) supported by the multiplexers with event log 2 being usedas the standard event log for sending events to the NMS. Event logs 1 and 3 can provide thecapability to send event log messages from the node to another Series 700 node or to an event logprinter.
