Transition Networks Achieves MEF Carrier Ethernet 2.0 Certification

Transition Networks Inc., the fiber access technology expert, today announced that it has received Metro Ethernet Forum (MEF) Carrier Ethernet (CE) 2.0 certification of its new 10-Gigabit Ethernet (10GbE) S4140 Carrier Ethernet network interface device (NID) and S4224 Carrier Ethernet access switch.

The S4140 features four 1/10 GbE ports and gives carriers a cost-effective network demarcation device that can address growing bandwidth needs for next-generation services. The S4224 switch has 24 100/1000Mbps ports and four 10GbE-uplinks and aggregates traffic from demarcation devices for efficient transport to the core network. Both devices feature support for IEEE 1588v2 and synchronous Ethernet, the two leading synchronization standards for wireless backhaul applications.

Transition Networks’ S4140 and S4224 bring simplified service creation to the edge of the network through the Converge™ EMS service automation software. This allows carriers to provision a wide range of Carrier Ethernet 2.0 services for mobile backhaul, business Ethernet, cloud assurance and carrier exchange E-Access services within hours from a central console.

The MEF Carrier Ethernet Certification Program is designed to ensure that global equipment and services comply with MEF standards and pave the way for interoperability. Carrier Ethernet 2.0 equipment certification includes E-Line, E-LAN, E-Tree and E-Access. Introduced in 2013, certification requires 634 test cases. Transition Networks was in the first round of Carrier Ethernet vendors to receive MEF CE 2.0 certification on its S3280 100/1000 Ethernet NID.

“Changes in enterprises – ranging from cloud computing to software-defined networks – are driving demand for Carrier Ethernet 2.0. We’ve engineered the S4140 and S4224 and our Converge EMS platform to help carriers be first to market with flexible CE 2.0 services,” said Kevin Faulds, director of product management at Transition Networks. “We recognize the importance of standards compliance, which is why we’ve taken a leadership role in ensuring that our systems are MEF compliant and certified.”

The MEF certification program has been a significant contribution to the successful worldwide deployment of Carrier Ethernet worldwide with around 500 certified products from more 75 equipment manufacturers deployed by more than 70 service providers. For more information, visit
