Description: This attribute displays the Local Management Interface network side procedure event history in order of occurrence. An event is represented by a single symbol. A '+' symbol indicates a good event. An 'X' symbol indicates a protocol error event. The leftmost event is the most recent to occur. The provisioned eventCount (nN3/ N393) dictates the maximum number of events displayed. A good event is triggered by receipt of a valid status enquiry message. An error event is one of three possibilities, either a nT2/T392 timer expiry, receipt of a status enquiry message with bad sequence numbers, or when lmiProcedures is provisioned to vendorForum and we receive more than nN4 status enquiry messages within the provisioned messageCountTimer (nT3).
