Quidway® AR18-3X Series Routers
Product Overview
Quidway® AR18-3X Series Routers, launched by Huawei Technologies, are oriented to small
office home office (SOHO) users. They include AR18-30E/31E/32E/33/33E/34/34E/35E models.
AR18-3X Series Routers belong to xDSL routers and provide a new solution to high
bandwidth-consuming small and medium-sized enterprises or some large branches and offices.
In the uplink direction, Quidway® A R18-3X Series Ro uters provide the ADSL/ADSL2+, G.SHDSL
or ISDN interface, which can be directly connected to the equipment at the central office through
one or two subscriber lines to provide broadband access services. The ISDN interface primarily
functions as a backup interface.
In the downlink direction, Quidway® AR18-3X Series Routers provide four 10/100BASE-T
Ethernet interfaces. The interfaces provide Layer 2 data exchange and can implement port
isolation.
The AR18-33/18-34/18-33E/18-34E is based on SHDSL access of ATM. The AR 18-33/34
supports single-pair wiring, and the AR 18-33E/34E support dual-pair wiring. The AR 18-30E/31E
provides the ADSL2+ over POTS (Annex A standard) interface, and the AR 18-32E/35E the
ADSL2+ over ISDN (Annex B standard) interface. They provide symmetric uplink and downlink
broadband leased line access over the twisted pair cables for those small and medium-sized
enterprises and SOHO users, who is not capable of building their private networks or cannot
afford high expenses of DDN communication. The AR 18-30E/31E/32E/35E has the switched
Ethernet interface and support VLAN management.

Features
Network Security
Quidway® AR 18-3X Series Routers provide abundant network security features, such as
firewall, packet filtering, network address translation (NAT), authentication, authorization and
accounting (AAA), and callback. Hence, users can select different security policies to build
enterprise networks.
Building a VPN
Intranet virtual private network (VPN) interconnects the geographically dispersed branches of a
company via public networks, as an extension and replacement of traditional leased line
networks and other enterprise networks. Access VPN provides secure tunnels for small-sized
users like SOHO to access the resources of company headquarters via PSTN/ISDN. Extranet
VPN extends the enterprise networks to the business partners and cl ients, and e nables dif f erent
companies to communicate securely and privately over the public networks. Quidway® AR
18-3X Series Routers are mainly used at the access end of VPNs.
Dial Control Center
Quidway® AR 18-3X Series Routers provide perfect dial-in solutions and support two dial-in
modes, namely legacy DCC and dialer profiles. In addition, they also support the link layer
protocols like point to point protocol (PPP), the network layer protocols like internet protocol (IP)
and internet packet exchange (IPX); they have the capability of running multiple dynamic routing
protocols on the dial-in interfaces; they thereby can satisfy various network topology
requirements. The dialer profiles own more functions, and can enable multiple dial-in users to
share a physical interface via the dialer pool and make different calls.
Reliability
The backup center technology can greatly enhance the network reliability. The features of ISDN
BRI interface implement line backup and provide high reliability.
