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).


Quidway® AR28 series router is illustrated as follows:

Applications & Benefits

Enterprise VPN Application Scenario

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

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

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.
