The TL1 protocol is the backbone of network management in the telecommunications domain. Although TL1 is simple and easy to use, developing complex application using TL1 is very difficult. The AdventNet Agent Toolkit C Edition provides intuitive and innovative tools for rapid development of robust TL1 agents with much ease.

The Agent Toolkit uses the concept of XML-driven TCS files (TL1 Command Set file) which defines the management information for the TL1 Agent. The TCS file is the equivalent of the MIB in an SNMP agent. The following topics are described in this section:

• Standalone TL1 Agent Architecture

• Defining a TCS File

• Defining a Data Set File

• Creating a Simple Agent Using Agent Compiler

• Testing the Agent

• Configuring Agent Settings

• Generated Code Structure

• Instrumenting the Generated Code

• Sending Autonomous Messages

• Using Delayed Activation

• Using Built-In Commands

• Using Self-Monitoring

• Enabling Asynchronous Message Processing

• Gateway Network Element

• Customizing Error Codes

• Persistence Storage Support

• Adding Logging to TL1 Agents

• Configuring Automatic Acknowledgment

• Sending Multiple Response Messages

• Using APIs for Configuring Timer-Scheduler

• Enabling Craft Interface

• Command Line Features

• Plugging in Other Transport Protocols

• Building Multi-Protocol TL1 Agents

• Security in TL1
