Transition Networks' Carrier Ethernet solution delivers the promise of simplicity deployed. This comprehensive solution includes CE 2.0 compliant demarcation devices, access switches, and the Converge element and service management platform.

With the goal of enabling new service generating revenue, Transition Networks' S4212 access switch with 12 100/1000Mbps ports and 2 10GE uplinks is designed to support a wide range of MEF-based Carrier Ethernet services for Mobile Backhaul, Business Ethernet, Cloud Assurance and Carrier Exchange E-Access Services.

Transition Networks' Converge platform is designed to simplify service provisioning with rapid service design and automated service activation capabilities. It's easy, intuitive pro-active fault and performance management make managing the complete service life cycle simple while reducing operating expenses. Converge is one of the first industry management platforms that integrates MEF defined CE 2.0 services and features template based provisioning that takes the complexity out of the provisioning process today while its open architecture and REST APIs provide a path forward for new software defined services and applications.
