Carrier Ethernet Services Explained provides an overview of Carrier Ethernet technologies, the relevant MEF CE 2.0 and MEF 3.0 specifications for services. The focus of the course is on inter-operator and global carrier ethernet services, quality of service and service operations administration and maintenance.

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 (Blueprint D) exam.


Upon completion candidates will be able to:

  • Describe in detail Carrier Ethernet Services and Service Attributes 
  • Identify how to build networks to deliver Carrier Ethernet Services
  • Compare operational alternatives for service delivery across multiple operator's platforms to provide global carrier ethernet services
  • Identify how quality of service and security can be guaranteed
  • Understand L2CP protocol processing, Bandwidth Profile Flow/Envelope configuration and behaviour
  • Describe how CE bandwidth profile works and how to implement Class of Service (CoS)
  • Understand the implementation and configuration of carrier ethernet services within the Mobile Transport 
  • Understand Ethernet SOAM and the requirements of Fault Management & Performance Monitoring
  • Be able to define Carrier Ethernet service solutions, across single and multiple CENs, that will meet the requirements of the Subscriber

Target Audience

Who Should Attend:

Anyone 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 Blueprint D 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:

The exam is a 1 hour 45 minutes online exam consisting of 80 multiple choice questions and is delivered under MEF advised test conditions, in a virtual or physical format. When booking the course, we are able to book candidates in for the exam at the same time.

Candidates sitting the Carrier Ethernet Services Explained course can choose to either sit the MEF-CECP exam as part of an optional Day 5 MEF Exam Readiness Session. This is an optional session designed to greatly increase exam performance ensuring as many candidates as possible pass the exam first time, if this is your first MEF exam we highly advise adding the Exam Readiness Session to your package. For those taking the Exam Readiness Session we also offer a free retake of the exam should anyone fail to pass the exam first time. Recertifying candidates or those wishing not to add the Exam Readiness Session can take the exam virtually in the days following the workshop.

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.
