Quidway AR18 Series Routers

Overview

Quidway AR18 Series Routers, launched by Huawei Technologies, are oriented to small office home office (SOHO) users.Because of the complex applications and varieties of uplink types, Quidway AR18 Series Routers were launched as three sub-series according to the uplink interfaces, consisting of Quidway AR18-3X Series xDSL Routers, Quidway AR18-2X Series LAN Routers and Quidway AR18-1X Series Routers.

H3C AR 18-2X Series Branch Access Routers

The H3C AR 18-2x Series Ethernet Routers are ideally suited for broadband SOHO applications that require fast Ethernet interfaces, robust packet processing capability, abundant services and a streamline design. The H3C AR 18-2x Series Routers feature cost-effective high performance, and can be applied in SOHO solutions and SME’s as a branch router. This series includes the AR 18-21/22/22S-8/22-24/18-21A models.

  H3C AR 18-2x Ethernet Routers consist of three types in terms of LAN interface density:

  * AR 18-21/18-22/18-21A (Four LAN Interfaces)

  * AR 18-22S-8(Eight LAN Interfaces) features hardware encryption
with high density LAN interfaces.
  * AR 18-22-24 (Twenty-four LAN Interfaces) has the densest LAN interfaces.


 
The H3C AR 18-2x Series provide 10/100BASE-Tx interface in the uplink direction and 10/100BASE-T Ethernet interface in the downlink direction. Data exchange between these ports is via layer 2 switching and port isolation can be implemented. In addition, the built-in hardware encryption chip of AR 18-22S-8 greatly enhances encryption performance.
 
  H3C AR 18-3X Series Branch Access Routers

The H3C AR 18-3x Series Routers are ideally suited for SMB and Small Office Home Office (SOHO) applications. The H3C AR 18-3x Series includes the AR 18-30E/18-31E/18-32E/18-33/18-33E/18-34/18-34E/18-35E models. The AR 18-3x Series Router supports xDSL and provides a new solution for situations where high bandwidth is required such as small and medium-sized enterprises and some large branch offices.

In the uplink direction, the H3C AR 18-3x Series provides ADSL/ADSL2+, G.SHDSL interface or ISDN interface.

 

This directly connects to equipment at the central office through one or two subscriber lines providing a robust solution for broadband network access. The ISDN interface primarily functions as a backup interface.

In the downlink direction, H3C AR 18-3x Series provides four 10/100BASE-T Ethernet ports. Data exchange between these ports is via layer 2 switching and port isolation can be implemented. The AR 18-33/18-34/18-33E/18-34E is based on SHDSL access over ATM. The AR 18-33/34 supports two-wire mode while AR 18-33E/34E supports four-wire mode. The AR 18-30E/31E supports ADSL2+ over POTS (ANNEX A Standard) interface while AR 18-32E/35E supports ADSL2+ over ISDN (ANNEX B Standard) interface.
