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-defined
parameters 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-defined
parameters 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.
