AR28

Quidway® AR28 series routers adopt the modular structure, can provide abundant optional Smart Interface Card (SIC) and Multifunctional Interface Module (MIM) modules. Quidway® AR 28 series routers consist of 4 sub-series: AR 28-40/80, AR 28-30/31, AR 28-1x, AR 28-09. How to divide the sub-series lies on the difference of forwarding performance and interface number. All of the Quidway® AR 28 series routers based on the Huawei’s mature Versatile Routing Platform (VRP).

Applications & Benefits


Enterprise VPN Application Scenario
2

AR 28 series routers support IPSec/GRE/L2TP VPN tunnel between headquarter and branches to satisfy enterprise security interworking requirements, realizing access authority control for enterprise customers, mobile users and branches.

Enterprise VoIP Application Scenario
2

AR28 series routers integrated main voice features and basic PBX service functions, support VoIP service through WAN, and supply high density FXS/FXO/E1VI/E&M voice interface cards to realize the transmission of the voice, data, and fax signals on the data communication network.

Enterprise Campus Application Scenario
2

AR28 series routers act as the egress router of campus network, access Internet or carrier network trough Ethernet/E1/xDSL/ISDN interface card. The AR28 can bear data, voice and video services to meet customer requirement of interworking between enterprise headquarter branches.
