The routing block contains a target identifier parameter with parameter name Target Identification (TID). The TID may be any valid simple or compound TL1 identifier or text string, and is limited to 20 ASCII characters. A valid text string or the TID is defined as letters, numbers, and hyphens within double quotes. TIDs are configurable items that can be defined using TL1 provisioning driven messages. The TID is the destination code for the command. For a Network Element (NE) to accept the command the TID must be the same as the NE’s system identification, which the user sets through the SET-SID command. A null TID entry for any TL1 command defaults to the system identification.

The access block identifies the circuit (T1, T2, T3, or HDSL) or equipment related to the command function. For commands that relate to the system itself rather than a specific circuit or equipment, no access block entry is required or permitted. When using the command modifier ALL, the access block must be null.

For commands that relate to a specific circuit access point, an access identification (AID) is required.

The fourth required block is called the message correlation block and contains one parameter to serve as a Correlation Tag (CTAG). The CTAG parameter correlates an input command with its associated output response(s). The user assigns a CTAG value and it is the responsibility of the NE to copy this value into the appropriate field of the output response(s) associated with that input command. The value of a CTAG must either be a TL1 identifier or decimal numeral, consisting of no more than six characters. An example of a valid CTAG is 123 in the following command:

REPT-STAT ::: 123;

The data block contains all parameters that are required by the NE to complete the command. The data block is command specific and is described in each specific command and response. Parameters are separated by commas. Parameter grouping is allowed for some parameters to provide a nonsequential series of singly defined data items. An ampersand (&) is used to separate each item. An example of parameter grouping is shown in the following command:

RTRV-ATTR-T1 : SONEPLEX : 1-2-3-1:123: : ,LOS & LOF;

All parameters are either position- or keyword-defined. Position-definedparameters are defined by the location or order that they are entered. White space or nothing between two commas indicates a null value selection for the parameter defined in that position. Keyword-definedparameters may be entered in any position in the block by entering the keyword and an equal sign followed by the value being selected. A missing keyword implies selection of a null value for that parameter (usually the default value). No extra commas may be entered to imply a null default selection and no keyword may be entered without a value being entered. All parameters are position-defined unless keyword-defined is specified in the command syntax description.
