Carrier Ethernet Services Explained provides an overview of Carrier Ethernet technologies, the MEF CE 2.0 specifications for services. It details how these services can be delivered over carrier core, metro and access networks along with other services deployed over a range of core transport and access technologies. It then provides a solid introduction to the principles of network and service design.

We understand it’s not just about passing an exam, but giving our students the opportunity to prove their worth by demonstrating a first-class understanding of the relevant technology. Our blended learning approach allows candidates to benefit from a wider understanding of associated technologies and skills to apply in the workplace, as well as acquiring the relevant skills to pass the MEF-CECP exam.

We stay with our customers following the MEF-CECP, providing multi-level, multi-technology training programs at the same high level as our carrier ethernet training. Perpetual Solutions has delivered multi-technology training programs to organisations who have taken our MEF-CECP training, covering topics such as OTN (Optical Transport Networks), LTE, Mobile Backhaul, MPLS and SDN/NFV. With over 2000 courses to choose from, we aim to be your knowledge partner of choice over the long term.


Upon completion candidates will be able to:

  • Describe in detail Carrier Ethernet Services and Functions
  • Identify how to build networks to deliver Carrier Ethernet Services
  • Describe how Ethernet services can be delivered over MPLS and Provider Backbone Transports
  • Compare operational alternatives for service delivery, Metro, Access, and Core architecture
  • Examine options for delivery of next generation services over Metro Ethernet
  • Identify how quality of service and security can be guaranteed

Target Audience

Who Should Attend:

Any requiring an in-depth knowledge of Carrier Ethernet and MEF standards and specifications. This includes Pre-sales Engineers, Network Engineers, Product Specialists and other job roles.

Additional Information

Pre-course preparation:

To ensure that candidates have the greatest opportunity to both pass the MEF-CECP exam and succeed in the workplace thereafter, Perpetual Solutions provides a unique set of pre-course preparation resources.

Pre-course skills assessment:

Our MEF-CECP pre-course skills assessment is free, and a quick way for candidates to check if they have the prerequisite level of knowledge in order to succeed on the course, at the exam and in the workplace. The assessment can be taken online and checks knowledge of fundamentals such as IP, WAN and Next Generation network principles.

Online learning modules:

For candidates whom the pre-course skills assessment identifies knowledge gaps, Perpetual Solutions offers a range of online, self-learning modules. These modules cover all the areas of fundamental knowledge required for MEF-CECP training including:

  •  IP & Transport Layer Technologies
  • Ethernet Principles for the LAN Environment
  • Layer 1 Transport Technologies
  • Layer 2 Transport Technologies
  • Layer 2.5 Transport Technologies
  • Access Technologies 

Certification & Exam:

Candidates sitting the Carrier Ethernet Services Explained course can sit the MEF-CECP exam on the final day of the course. The exam is a 1 hour 45 minutes online exam consisting of 80 multiple choice questions and is delivered under MEF advised test conditions. When booking the course, we are able to book candidates in for the exam at the same time.

To ensure that as many candidates as possible pass the exam first time, we provide a unique range of prequalification and foundation learning solutions. In addition, we also offer a free place to re-sit the exam should anyone fail to pass the exam first time.

Due to the fast moving nature of the technology and continual improvements and additions the MEF makes to the MEF standards the MEF-CECP certification expires after 3 years.
