Introduction
This introduction covers the following topics:
What is in this guide
This guide describes how to manage the MAX TNT and troubleshoot its operations. It assumes that you have set up the MAX TNT system as described in the MAX TNT Hardware Installation Guide and configured it for network connectivity as described in the MAX TNT Network Guide.
Each chapter in the guide focuses on a particular aspect of MAX TNT administration and operations. The chapters describe tools for system management, network management, and SNMP management.
Although some of the sections in this manual deal with security issues, the MAX TNT Network Guide provides a more comprehensive approach to such topics as securing the unit, using firewalls, and understanding the more complex authentication procedures (such as the use of dynamic passwords).
To perform many of the tasks in this manual, you must have administrative permission on the MAX TNT. For instructions on logging into the MAX TNT with administrative permissions, see Logging into the MAX TNT.
What you should know
While this guide attempts to provide a conceptual framework that will sufficiently enable an administrator who is not an expert in a particular network technology to operate and troubleshoot the unit, it does not start from the beginning with any network management topic. Following are the general areas in which it is helpful to have some existing knowledge when working with the related capability in the MAX TNT:
- Line configuration and testing
- Dial-in connections such as PPP or clear TCP
- Connection negotiation and authentication
- Connection-cost management and accounting
- ISDN
- Modems
- Frame Relay
- IP routing
- OSPF routing (if applicable)
- Multicast (if applicable)
- Network security
Related publications
Additional information is available in the other guides in the MAX TNT documentation set. If you need more background information than these guides provide, many external references are readily available on the Web or in technical bookstores. You'll find a partial list of such references below.
MAX TNT documentation set
The MAX TNT documentation set consists of the following manuals:
- The Ascend Command-Line Interface. Shows how to use the MAX TNT command-line interface effectively.
- MAX TNT Hardware Installation Guide. Describes how to install the MAX TNT hardware and use the command-line interface to configure its slot cards for a variety of supported uses. Describes how calls are routed through the system. Includes the MAX TNT technical specifications and some administrative information.
- MAX TNT Network Guide. Describes how to use the command-line interface to configure WAN connections and other related features.
- MAX TNT RADIUS Configuration Guide. Describes how to use RADIUS to configure WAN connections and other related features.
- MAX TNT Reference Guide. An alphabetic reference to all MAX TNT profiles, parameters, and commands.
- MAX TNT Administration Guide (this manual). Contains troubleshooting and administrative information.
