1.2 Autonomous Message Syntax
"d" is the correlation tag (CTAG)
"e: ... z;" are other positions required for various commands
The TID, AID, and CTAG route and control the TL1 command. Other parameters provide additional
information required to complete the action requested by the command. TL1 command codes, parameter
names and parameter values can be either uppercase or lowercase exclusively or any combination of the
two, unless specifically noted in the command description.
The TID is a unique name given to each system when it is installed. The name identifies the particular
NE (in this case, the ONS 15454, ONS 15327, ONS 15310-CL, and ONS 15600), to which each
command is directed. The value of TID can be any TL1 identifier or text string, but it is limited to 20
characters. An identifier contains any number of letters or digits, but must start with a letter. A text string
is any alphanumeric or punctuation character enclosed in double-quotes. The presence of the TID is
required in all input commands, but its value can be null (represented by two successive colons). The
TID can be null when the operating system directly communicates with the target NE. The recommended
value for the TID, when it is used, is the target's common language location identifier (CLLI) code. To
establish the TID for a node, use the Provisioning > General tabs in CTC.
The AID is an access code used to identify and address specific objects within the NE. These objects
include individual pieces of equipment, transport spans, access tributaries, and other objects.
The CTAG is a unique identifier given to each input command by the user. When the NE responds to a
specific command, it includes the command's CTAG in the reply. Including the CTAG eliminates
discrepancies about which response corresponds to which command. Valid CTAG values include strings
of up to six characters comprised of identifiers (alphanumeric, beginning with a letter) or decimal
numerals (a string of decimal digits with an optional non-trailing ".").
The following specification characters are used throughout this document as vehicles for defining the
syntax:

1.2 Autonomous Message Syntax
Autonomous messages are used to report alarms, configuration changes or condition changes. Many of
these messages, such as those relating to alarm conditions, are spontaneously triggered by the NE itself
without intervention. Other messages, such as those relating to the reporting of periodic condition states
or performance data values are scheduled by the NE user via other commands. Because you do not issue
autonomous messages to the NE, they do not include input formats or input examples.
The autonomous TL1 messages are included in the Cisco ONS SONET TL1 Command Guide.
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 NE. Cisco NEs
use whole numbers 0000 to 9999.
Note Some autonomous messages (REPT DBCHG and REPT EVT SESSION, for example) differ slightly
from the format shown in the third line of
Cisco ONS SONET TL1 Command Guide, R6.0
1-2
< > enclose a symbol specifier, for example <CTAG>.
[ ] enclose an optional symbol, for example [<TID>].
" " enclose a literal character, for example an output format
"SLOT-7:PLUGIN,TC,,,,,,,:\"EQUIPMENT PLUG-IN\",TCC"
^ is a space, a literal blank character used only in examples of messages.
