Course Overview

Course in a Nutshell

Asynchronous Transfer Mode (ATM) is a widely deployed technology known for its flexibility and support of multimedia data traffic. ATM is a key component of broadband ISDN (B-ISDN) and for some people it still holds promise as the single integrating network technology. However, it’s also a very complex technology to learn and manage.
This course, designed as a practical survival guide, deals with all of the key ATM issues including architecture, user-network interface, LAN and WAN implementation, enhanced functionality, network management using SNMP, traffic engineering, and more. You will go away from this course with a solid set of skills to help deal with your ATM network.


Customize It!

Let us know your background and reason for studying ATM so we can customize the course to your specific needs. If you need to learn SONET/SDH, SNMP, or other technologies in conjunction with ATM, we can also structure combination courses for you. Most customization is performed at little to no added charge.


Learn How To

  • Define and use the important ATM terms
  • Become a confident user of ATM
  • Name the ATM suppliers, products, carriers, and users
  • Summarize the most promising ATM business goals, structures, applications, and services
  • Name the factors critical to the assessment, deployment, and management of ATM
  • Use the selection criteria for determining where ATM can be safely applied
  • Minimize your risk for selecting and using ATM and new vendors
  • Identify what’s missing from ATM capabilities and the migration obstacles
  • Employ proper products and strategies for migrating your office LANs and WANs to ATM
  • Determine if you should first use ATM on your LANs, WANs, voice, or video
  • Integrate your LAN/WAN networks with voice, video, and facsimile networks
  • Utilize SNMP’s ATM MIBs to help manage your ATM products
  • Leverage ATM enhancements such as ABR, P-NNI, LAN Emulation, MPOA
  • Describe Cisco’s Tag Switching and Multi-Protocol Label Switching (MPLS) technologies
  • Identify and pursue key ATM issues and ask more penetrating questions
  • Anticipate and minimize network management and reliability problems
  • Budget and evaluate costs and cost savings more effectively
  • Describe ATM Classes of Service and Traffic Management
  • Avoid being disappointed by management products and performance
