Carrier Ethernet Services Explained provides a technical understanding of Carrier Ethernet technologies and the latest Carrier Ethernet 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 exam (latest Blueprint E).


Upon completion candidates will be able to:

  • Describe in detail Carrier Ethernet Services and be able to determine suitable parameter values for the latest MEF 3.0 Service Attributes
  • Identify how to build networks to deliver Carrier Ethernet Services
  • Compare operational alternatives for service delivery across single and multiple operator's platforms to provide global carrier ethernet services
  • Identify how quality of service and security can be guaranteed
  • Describe how the Carrier Ethernet Bandwidth Profile works and how to implement Class of Service (CoS)
  • Understand Bandwidth Profile Flow and Envelope configuration and behavior
  • Understand the implementation and configuration of Carrier Ethernet Services within the Mobile Transport infrastructure
  • Understand Ethernet SOAM and the requirements and procedures associated with 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 E 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.

Delivery Options for MEF-CECP Training and Exam

Public Training Schedule: The Public Training Schedule has dates available globally, please view available dates here.

Onsite training: Perpetual Solutions can deliver MEF-CECP Training and Examination at your company offices or, if you have no training facility onsite, at a third party venue in your city. Onsite training is available globally and is ideal for groups of four or more people. If you have a group of colleagues requiring this program, please call us or send an enquiry.
