Metro fibre networx User Network Interface (UNI) is the physical 10/100/1000Mbps Ethernet interface or port that is the demarcation between the customer and the service providers network.
Metro fibre networx will always provide the UNI at the customer’s site, unless the service is a Standard (Basic) SLA service that is only provisioned with a low costing Fibre to UTP Converter. In this case the UNI will be the Access Ethernet Switch Port.
The Performance and Service Availability monitoring for each of the Class of Service guarantees offered, will be monitored across the entire Metrofibre networx
Monitoring can be either between UNI to UNI for services that reside entirely on the Metrofibre networx (ON-NET), or between UNI to E-NNI (External Network Node Interface) for services that are provisioned Network-to-Network, between network clouds operated by one or more service providers.
Metro fibre networx is a “Carrier Class Open Access” Metro Ethernet Network that is “Open” to all Service Providers, to deliver content to their customers on equal terms and designed to provide a high-level of SLA based Performance Assurance, based on the Metro Ethernet Form (MEF) 9/14.
