Overview

14 TimeProvider TL1 Reference Guide 097-58001-01 Revision E – September 2006

Overview

Transaction Language 1 (TL1) is the most widely used management language in

the telecommunications industry. TL1 provides a standardized set of

vendor-independent, ASCII-based instructions that can be used to manage network

elements (NEs) and their resources. The TimeProvider uses TL1 as its

human-to-machine command line interface (CLI).

The remainder of this chapter explains the TL1 command language and how it

applies to the TimeProvider.

TL1 Command Structure

The TL1 commands used in the TimeProvider consist of the following three main

parts, or blocks:

 The Command Code Block

 The Staging Block

 The Payload Block

These three main blocks are separated by a colon ( : ) block separator character

and the command is terminated by a semicolon ( ; ) terminating character. The

semicolon indicates that the command statement is completed and the command is

then executed.

Figure 1-1 shows the typical structure of a TL1 command, and the paragraphs that

follow further explain the elements that constitute each of the main blocks.
