Neptune 1250 High Availability Access Router for Access Edge and Pre-Aggregation The Neptune (NPT) 1250 is a fully redundant, modular router designed to provide a multi-access edge and pre-aggregation for services, applications and architectures requiring a high-availability multiservice solution. With support for eCPRI, XGSPON, network slicing, advanced timing and multiple access technologies, it is ideal for operators who want a multi-access Hub in their xHaul network. NPT 1250 provides 560Gbit interface switching, 300 Gbit/s processing capacity and 100G interfaces in a 2 RU form factor. It provides an extensive set of interfaces for multiple access technologies such as Ethernet, MPLS, PON and legacy TDM(CES), and has the capacity to be used for pre-aggregation or a large access edge deployment. With a full set IP/MPLS, transport capabilities, the NPT 1250 can efficiently aggregate and route the services over the network, meeting their service performance needs (SLAs) on a service by service basis. Full redundancy and support for segment routing and MPLS-TP make the NPT 1250 a perfect fit for operators delivering business and missioncritical services. NPT 1250 supports a full set of optical interfaces including 100G ZR/ZR+ coherent optical pluggables, this allows it to support both single layer, hop-by-hop IPoDWDM and multilayer IP and Optical transport. The operator can choose which approach best meets their needs, or they can run both in a hybrid approach. With such a rich and robust feature-set, the NPT 1250 is well suited for a wide variety of applications and networking scenarios, these include; • 5G multi-access Hub: with 5G specific functionality including, Class C timing, Segment Routing, Flex-Algo, EVPN, FlexE and 5G interfaces CIN Switch for MSOs: Providing the IP routing capabilities needed as MSOs evolve to CIN in a small compact form factor Mission critical applications and networks: With high availability and support for deterministic packet transport with MLPS-TP, segment routing and RSVP-TE Pre-aggregation for Broadband services: providing a full set of IP/MPLS capabilities providing optimized service-aware support for voice, video, and data services Rural connectivity Critical industries Super Converged Multi-AccessEdge Access Router Pre-aggregation and access edge for Residential Broadband and Business services: a full range of Ethernet interfaces and full set of IP protocols such as EVPN and segment routing ensure services are transported to meet the SLA’s on a per service basis TDM migration: supporting voice trunk and legacy service migration with circuit emulation services (CES) mapping a full range of legacy TDM interface speeds onto the packet switched network (PSN) PON infill: with a 10GSFP+ OLT Optics pluggable module providing XGS-PON/EPON connectivity supporting up to 128 ONUs per OL
