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 clients, and enables different
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.
