Huawei Quidway AR28-09 Modular Branch Routers
Quidway AR28-09 använder en modulär arkitektur och ger integrerade ”Fast Ethernet Interface”, AUX gränssnitt och synkrona /asynkrona seriella interface.
AR28-09 kan användas som accessrouter i större nätverk och som corerouter i små till medelstora företagsnätverk. Quidway AR 28-09 kan även användas tillsammans med andra routers/switchar från Quidway och ge heltäckande nätverkslösningar för medelstora/stora företagsnätverk, såsom telekombolag, Internetleverantörer mfl.
Overview
The Quidway AR28-09 intelligent service branch router is an edge access router. It adopts a modular architecture and provides integrated Fast Ethernet interfaces, AUX interface and synchronous/asynchronous serial interfaces. Further, it also offers optional smart interface card (SIC) and Multifunctional Interface Module (MIM). Compared with its equivalences, the Quidway AR 28-09 intelligent service branch router has higher performance cost and extensible capabilities. It can act as an access router in some large branches and as a core router in small- and mid-sized enterprise networks. Further, the Quidway AR 28-09 intelligent service branch routers can work together with other Quidway series routers, Ethernet switches to provide overall end-to-end network solutions for industry users and mid- and large-sized enterprise users, such as telecom, ISP, finance, tax, public security, and railway.
