The Accedian EtherNIDTM EE Demarcation Device (EDD) offers the solution to these challenges by implementing standardsbased OAM and loop-back capabilities. Providing a Performance Assurance AgentTM (PAATM) allows measuring and tracking End-to-End SLA parameters such as Latency,Jitter,Packet Loss and Availability in a continuous manner,while the service is running. Acting as an electrical port extension to basement-located Access Platforms the EtherNIDTM EE is the ideal vehicle to define a clear network boundary at the customer premises of multitenant commercial environments.The EtherNIDTM is also used at inter-carrier handoff points to sectionalize E-Lines that span across multiple service providers, thus eliminating finger pointing. Furthermore, the EtherNIDTM EE's high-performance Fast-ThruTM engine minimizes intrinsic packet-jitter and latency of the device, thus allowing the deployment of multiple units along an End-to-End Ethernet Service Path without introducing any significant latency or jitter to the service itself.
