Ethernet Demarcation

Ethernet demarcation is a key element in Carrier Ethernet transport and services as it provides a clear separation between the user and the network and allows carriers to extend network visibility into the user premises. Carrier control over the entire service path is achieved by connecting customer premises equipment (CPE) to the network with provider-owned demarcation devices that are deployed at customer locations. Such implements are known as Ethernet Demarcation Devices (EDDs), Customer Equipment (CE), Network Termination Equipment (NTE), Network Termination Units (NTUs), Network Interface Devices (NIDs), Network Interface Units (NIUs), or Network Demarcation Devices (NDDs). Intelligent Ethernet NTUs (E-NTUs) offer advanced functionalities such as service and link OAM, end-to-end traffic management starting at the service hand-off point (UNI – User Network Interface), extensive fault monitoring and diagnostics, uplink redundancy, and automated SLA verification.

RAD’s REAL (Reliable, Economical, Accountable, Limitless) Ethernet demarcation solutions provide end-to-end service visibility, along with performance monitoring, QoS and traffic management. Supporting service consistency across copper, DSL, and fiber, RAD’s EtherAccess® Ethernet demarcation devices and network termination units provide multiservice support to help service providers introduce new revenue-generating, SLA-based services. In addition to prioritizing traffic per user and per service, they ensure service resiliency and efficient troubleshooting via extensive Ethernet OAM statistics and diagnostics.
