Quidway AR 18-2X Series Routers Chapter 1 Product Overview
1.1 Introduction
Quidway AR 18-2X Series Routers (hereinafter referred to as the
AR 18-2X series) are Ethernet access routers designed for small
office home office (SOHO) subscribers. By far, the series have two
models: AR 18-20 and AR 18-20S. They provide an uplink Ethernet
interface and four downlink layer 2 (L2) switched 10/100BASE-T
Ethernet interfaces that can be isolated.
The AR 18-2X series support multiple virtual private network
(VPN) services, such as layer 2 tunneling protocol (L2TP) VPN, IP
security (IPSec) VPN, generic routing encapsulation (GRE) VPN, and
Huawei dynamic VPN (DVPN). They can provide tunnel connections
to remote users to build VPNs that can be internets, intranets, or
access networks.
The series support firewall, AAA (authentication, authorization,
accounting), network address translation (NAT), and quality of service
(QoS). Therefore, they can ensure security and guaranteed services
to the private networks constructed on the open Internet.
In the series the AR 18-20S has a build-in hardware encryption
chip, which can significantly improve encryption performance.
The interfaces that the AR 18-2X series provide are compliant
with the international standards and can work with the products of
other vendors at every layer. The existing investment of users can
thus be protected to the maximum.
