The <atag> parameter is the Autonomously Generated Correlation
Tag (ATAG). It is a decimal number assigned by the NE. It must be
sequential and must be included in all autonomous messages. The
ATAG allows an OS to determine if it has failed to receive any
autonomous outputs by checking for omissions in the sequence of
messages received.
The <verb>[^<modifier>[^<modifier>]] entry identifies the nature
of the autonomous output and allows for quick identification of the
semantics of the information in the text block. It consists of up to
three valid TL1 identifiers separated by the space character (^).
The first identifier (<verb>) is the autonomous message verb and is
a required entry. In most cases, the verb in an autonomous message
will be REPT (Report). The autonomous message verb can have up
to two optional modifiers. Thus, valid forms are <verb>,
<verb>^<modifier> and <verb>^<modifer>^<modifier>. The first
identifier following the verb is used to modify the verb. The
second modifier is used to specify the object generating the
message. Certain modifiers mean that the <aid> parameter (if it
exists) is addressing a particular type of entity in the NE.
<message block> is the detailed data related to the specific alarm or
report.
An example of an autonomous message alarm is:
Unit 1 01-10-09 16:20:05
*C 1 REPT ALM T3
"301:CR,LOS,SA,10-09,16-20-05,NEND,,,,"
In this example, "Unit 1" is the unit ID or <tid> that was set in the
menus. "01-10-09 16:20:05" is the date and time stamp. The "*C"
indicates that this is a critical alarm. "1" is the <atag> that is
automatically generated. "REPT ALM T3" is the <verb> and its
modifiers. The "301:CR,LOS,SA,10-09,16-20-05,NEND,,,," is the
message. The message contains the <aid>, then the type of alarm,
whether or not it is service affecting, the date in MM-DD format,
