Already popular in the enterprise LAN, Ethernet is being adopted in the WAN as an economical alternative to legacy services due to its simplicity and ease of deployment over almost any network infrastructure. Based on advances in industry standards, customers can expect carrier-class Ethernet services that meet their specific needs, better service granularity, and pricing based on different service levels.

CN 3116	8	8	Carrier Demarcation Device

The Ethernet-over-Fiber Network Termination Equipment (NTE) provides Carrier Ethernet transport over fiber local access connections in Gigabit Ethernet (GbE) format. This capability enables delivery of an intelligent Ethernet demarcation between customer and carrier networks and supports the latest Ethernet Operations, Administration and Maintenance (OAM) capabilities for testing and monitoring of both the LAN and WAN segments.

These devices deliver differentiated, granular and scalable services and ensure end-to-end service monitoring, diagnostics and enforcement of Service Level Agreements (SLAs). Remote upgradeability of features such as Quality of Service (QoS) parameters, bandwidth rate limiting, and uplink redundancy ensure carriers can satisfy both immediate and future customer needs, including the ability to adapt without costly forklift upgrades as industry standards change and evolve.
