1.3 Autonomous Messages
The autonomous TL1 messages are included in Chapter 3, “TL1 Command Descriptions” and listed
alphabetically. Figure 1-1 shows the autonomous message format. The autonomous message tag (ATAG)
is used for message sequencing. The number is incremented by one for each autonomous message sent
by the ONS 15454 or ONS 15327. The ONS 15454 and ONS 15327 use whole numbers 0000 to 9999.

1.3.1 Alarm Codes
The alarm code indicates the severity of the autonomous message. Valid values for alarm codes in
decreasing order of severity are as follows:
• *C Critical alarm
• ** Major alarm
• *^ Minor alarm
• A^ Non-alarm message
Critical, Major, and Minor correspond to the reporting of alarmed events. The Non-alarm message
designation is used when the NE is reporting non-alarmed events, periodic measurements, or results of
previously-scheduled diagnostics or audits. If multiple alarms are reported in the same message, the
alarm code is the highest severity of those being reported.
The following is an example of an output message that includes the Critical alarm code:
