APRIL 9, 2008 -- Telco Systems (search for Telco Systems) says that its T5Compact family of routing switches and T-Metro multi-service platforms are now certified to MEF 9 and MEF 14. These most recent certifications mean that the company's entire access and demarcation product line is fully MEF compliant, adds Telco Systems.
The company also says that its products that suppor CES are compatible with MEF 18 and will be certified to this standard in the near future. The complete product line is upgrade-ready for future compliance with UNI Type 2 and E-NNI certification, Telco Systems concludes.
The MEF-approved test plan, performed by Iometrix, defines requirements for delivery of services across an Ethernet Private Line (EPL), Ethernet Virtual Private Line (EVPL), and E-LAN (Ethernet-Local Area Network) networks. As service-oriented test specifications, MEF 9 and MEF 14 are defined from the subscriber's point of view at the user-network interface (UNI) where the subscriber and service provider areas of responsibility meet. MEF 9 encompasses service attributes such as CE-VLAN ID preservation, multiplexing, and bundling. MEF 14 tests for EVC-related performance including frame delay, frame delay variation, and frame loss ratio, as well as bandwidth profile service attributes including per ingress UNI, per EVC, and per class of service.
