frUniLmiUserSideEventHistory
Frame Relay Uni Lmi User Side Event History
This attribute displays the Local Management Interface user 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 left most 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 message. An error event is either a nT1/T391 timer expiry or receipt of a status message with bad sequence numbers.
