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. |
