Huawei Quidway AR18-1X Series Routers

AR 18-1X, framtagen av Huawei Technologies, är anpassad för det mindre kontoret/hemmakontoret. I serien ingår modellerna AR 18-10/18-12/18-13/18-15/18-16/18-18.

Serien ger användaren ett flertal gränssnitt som stödjer ethernet, multi-protocol synchronous/asynchronous serial, AUX, ISDN BRI S/T och U, CT1/PRI, E1-F och VoIP.

Stöd finns för sådana tekniker som V.24 DTE/DCE, V.35 DTE/DCE, X.21 DTE/DCE, RS449 DTE/DCE och RS 530 DTE. Lämpliga kablar för önskade gränssnitt behövs.

Quidway AR 18-1X stödjer flexibla nätverk med PSTN/ISDN, frame relay, X.25, digital data network (DDN), T1/E1, och andra WAN tekniker.

Väl tilltagna funktioner för säkerhet finns, bland annat SNA (System Network Architecture), DLSw (Data Link Switching), VLAN, Brygga och VPN samt IP multicast. Det finns också stöd för QoS (Quility of service)och VoIP (IP-telefoni). AR 18-1X kan också tjänstgöra som branch router för att arbeta tillsammans med andra routrar och switchar från Huawei, och skapa en heltäckande nätverkslösning, bland annat för Internetleverantörer, samt större och medelstora företag.

Overview

Quidway AR 18-1X Series Routers, developed by Huawei Technologies, are oriented to small office home office (SOHO) users. They include AR 18-10/18-12/18-13/18-15/18-16/18-18 models.

Quidway AR 18-1X Series Routers provide users with diversified interfaces supporting Ethernet interface, multi-protocol synchronous/asynchronous serial, AUX, ISDN BRI S/T and U, CT1/PRI, E1-F and VoIP. The multi-protocol synchronous/asynchronous serial interface supports such protocols as V.24 DTE/DCE, V.35 DTE/DCE, X.21 DTE/DCE, RS449 DTE/DCE and RS 530 DTE. You need to select appropriate cables for your desired interfaces. Quidway AR 18-1X Series Routers support flexible networking with PSTN/ISDN, frame relay, X.25, digital data network (DDN), T1/E1, and other WAN technologies.

Quidway AR 18-1X Series Routers provide abundant network security features, including system network architecture (SNA), data-link switching (DLSw), VLAN, Bridge, VPN and IP multicast. They also provide quality of service (QoS) and voice over internet protocol (VoIP) features. Thus, this series can act as branch routers to work together with other Quidway series routers and as Ethernet switches to provide a comprehensive end-to-end network solution for Internet service provider (ISP), large and medium-sized enterprise users, and industry users in telecommunication, finance, taxation, and railway.

Network Security

Quidway AR 18-1X Series Routers provide abundant network security features, such as firewall, packet filtering, network address translation (NAT), authentication, authorization and accounting (AAA), and callback. Hence, you 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 18-1X Series is mainly used at the access end of VPNs.

Dial Control Center

Quidway AR 18-1X Series provides perfect dial-in solutions and supports two dial-in modes, namely legacy DCC and dialer profiles. In addition, it supports 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 synchronous interface, asynchronous interface, CT1/PRI interface and ISDN BRI interface implement line backup and provide high reliability.

Command Line Interface

The command line interface (CLI) of Quidway AR 18-1X Series Routers can be configured in common ways. No special training is needed for users.

2B+D Data Transmission

The AR 18-13/18-13V/18-15/18-18V has the built-in terminal adapter (TA) and provides the ISDN BRI S/T interface or U interface for 2B+D data transmission.

T1/E1 Leased Line and PRI Dial-in Service

The AR 18-16/18-18/18-18V provide one CT1/PRI interface or E1-F interface. The CT1/PRI interface can provide the bandwidth of up to N x 56 Kbps or N x 64 Kbps for data transmission after being bundled into channel-groups. In addition, it can provide remote users with the dial-in service after being bundled into a pri-group. The E1-F interface supports only one bundle and does not provide the PRI dial-in service.

Chassis

Electromagnetic shielded plastic chassis, which the AR-1x Series adopts, has not only a smooth external appearance and small size, but also can effectively shield electromagnetic interference from various sources to make the system work more stably and reliably.
