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 a single integrating network technology. However, it’s also a very complex technology to learn and manage.

This ATM Training or Asynchronous Transfer Mode (ATM) Training 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

  • 3 days of ATM Training or Asynchronous Transfer Mode (ATM) Training with an expert instructor
  • ATM Training Electronic Course Guide
  • Certificate of Completion
  • 100% Satisfaction Guarantee



After completing this ATM course, students will be able to:

  • Define and use the important ATM terms
  • Become a confident user of the 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 ATMs 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
  • Identify what ATM test equipment is available and what you need
  • Evaluate job applicants and vendors better
  • 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.
