Huawei ATN 950B Full Product Description
Product Overview
The Huawei ATN 950B is a carrier‑grade 2U modular multi‑service access router for IP‑RAN mobile backhaul and metropolitan private‑line servicesHuawei Car.... Built on programmable NP forwarding hardware and running Huawei VRP operating system, it adopts a compact 6‑slot modular chassis with flexible service card expansion. It supports mixed TDM and Ethernet service access, high‑precision timing synchronization, MPLS‑TP, SR‑MPLS, SRv6 and EVPN. It is widely deployed for 2G/3G/4G/5G base‑station backhaul, enterprise VIP leased‑lines and FMC converged bearer scenarios, cooperating with core routers to build end‑to‑end packet transport networks for operatorsHuawei Car....
