See the definition of this variable above for details about this filter, and the other trap filtering mechanisms. The 'trapSequenceNumber,' variable bound within the trap can be used by management stations and network administrators to detect when a trap has been lost during transmission. The 'mgmtT1AISSeverity' variable bound within the trap indicates the configured severity level associated with this event. A value of 'NORMAL', indicates that the T1 AIS Output condition is normal. A value of 'T1AIS-ALM', indicates that the Radio is generating 'Alarm Indication Signal', or marking the T1 line with all ones, on the transmit output.When this occurs there is an interruption in the RF signal due to 'FRAME-LOSS', 'BER-3', or a 'DEMUX' hard alarm conditions. The row/column variables included in the trap are: system.trap.trapSequenceNumber; radio.mgmt.mgmtT1AISSeverity.
