the reference clock source. The systemStatusGeneralGroup also contains the statusDescriptorStr object 
that returns a text string identical to the output of the F73 command on the command line interface. The 
systemStatusDetail group contains objects describing the current status of each system object. See the 
graph above and refer to the xliSystem-SMIv2.mib MIB for a complete description of each object. 

At present the xliMainCard group contains only the NTP subgroup as shown above. Refer to the 
xliMainCard-SMIv2.mib MIB definitions for a description of each of the NTP statistics.

All traps for the XLI product are defined under Truetime.products.xli.xliTraps. This is required to maintain 
compatibility with MIBS defined using the Structure of Management Information version 1 definitions. 

The XLI SNMP agent will send SNMP version 1 traps. This is done to maintain compatibility with 
SNMPv1 managers.

The traps presently defined are: alarmSystemNotification

The alarmSystemNotification trap is sent when the state of an object in the systemStatusDetail group 
changes and the corresponding mask object in the configDataMasks group is enabled.

This section outlines the possibilities for future expansion of the TrueTime Enterprise MIB. The general 
overview is that new objects may be added to any location. Existing objects may not be altered in order
