Chapter 1 Product Overview

1.1 Introduction

H3C AR 18-3XE Series Routers and AR 18-21X Series Routers are ADSL2+ routers that H3C Technology developed for small office home office (SOHO) subscribers.

H3C AR 18-3XE/18-21X Series Routers include AR 18-30E, AR 18-31E, AR 18-32E , AR 18-35E, AR 18-21A and AR 18-21B.

The AR 18-3XE series provides an ADSL/ADSL2/ADSL2+ interface in the uplink direction to connect to the central office device through a subscriber line, thus providing broadband access to the Internet. In this series, the AR 18-31E and the AR 18-35E provide ISDN backup. When the ADSL/ADSL2/ADSL2+ link fails, the ISDN interface can take over to ensure ongoing communications. In the downlink direction, the AR 18-3XE series provides four 10/100BASE-TX layer 2 (L2) Ethernet ports which can be isolated via VLAN configuration.

The AR 18-21X series provides one Ethernet interface in uplink direction and uses an ADSL/ADSL2/ADSL2+ interface for backup. In the downlink direction, the series provides four L2 10/100BASE-TX switched Ethernet ports which can be isolated via VLAN co nfiguration.

The interfaces provided by the AR 18-3XE/18-21X series are compliant with international standard s and can work with the product s of other vendors at all layers of the network. This helps to prote ct your existing investment to the maximum.
