NPT 1800 Overview

The NPT 1800 streamlines end-to-end metro service delivery by providing carrier-grade service assurance, high availability, visibility, and control with unparalleled multiservice support. Neptune 1800 combines carrier-grade service assurance and control with IP transport efficiency and multiservice aggregation and transport. NPT 1800 provides converged support for IP/MPLS, MPLS-TP, Ethernet (MEF certified), Segment Routing, and TDM over CES/CEP. With feature-rich IP routing features and capabilities, FlexE for network slicing and enhanced timing, NPT 1800 is well-suited for 5G  xHaul.
