TL1 command structure

Each TL1 command is divided into a set of positional parameters that represent actions or objects. TL1 commands must be typed accurately, with no spaces and with parameters separated by colons.

The following is an example TL1 command line:

COMMAND:TID:AID:CTAG:KEYWORD=DOMAIN:STATE;

TID, AID, and CTAG are used for routing and controlling the command. The other parameters provide the information to complete the action that the command requests. TL1 commands are not case-sensitive.

Commands, keywords, and domains can be strung together using commas. For example:

ED-SYS:TID::CTAG:::TMG=EXT1544,AAT=0,ADT=0;

Table 1 describes some of the TL1 parameters that you can use.

Table 1. TL1 command parameters
Parameter	Description
`AID`	The AID is an access code used to identify the exact address of the equipment or facilities (channels) within the command.
`AID Type`	The access identifier (AID) type specifies whether the AID applies to equipment, communications, or one of the traffic or data channels.
`CTAG`	The correlation tag (CTAG) is a unique identifier that the operator gives to each input command. When the network element responds to that command, it includes the CTAG of the command in the reply. This prevents any confusion about which response applies to which command. CTAGs consist of up to six ASCII characters.
`DOMAIN`	This parameter contains the list of possible settings for a given keyword. Only one value from the domain can be chosen for each use of the keyword. The proper domain setting must be chosen for the specified keyword when editing the system, equipment, or facilities. Keywords not used in a command are not affected by the command.
`PID`	The private identifier (PID) is the password associated with the UIS.
`SID`	The source identifier (SID) is the same as a TID, except that it is used when the network element is identifying itself in a response message.
`TID`	The target identifier (TID) is a unique name given to each system when it is installed in the network. This name identifies the particular network element to which each command is directed. Each TID comprises a maximum of 20 alphanumeric characters. Note: If the data in the parameter reserved for the TID is not data that has been assigned to any NE as a SID, the command receives a timeout response. When the parameter position reserved for the TID is empty, or null, the parameter defaults to the value placed in that position in the last command entered.
`UIS`	The user logon name.
