The AR1200 integrates routing, switching, 3G, WLAN, voice, & security functions. It uses the multi-core CPU & non-blocking switching structure & provides industry-leading system performance & extensibility, meeting service development requirements in the future. The AR1200 provides an integrated solution for enterprise networks, speeds up multi-service provision, & protects customers' investments. The AR1200 provides four models: AR1220, AR1220V, AR1220W & AR1220VW. Features 3rd Generation AR with Industry-Leading Performance The AR1200 uses the multi-core CPU & non-blocking switching structure & provides industry-leading system performance, meeting network extension requirements & service development requirements of enterprises. Dual-Mode Network, Supporting Flexible Access The AR1200 not only supports wireless mode WLAN, UMTS, LTE, but also supports wired mode fiber, copper cable, which provide customer flexible ways to access network. Services Integrated on One Router The AR1200 integrates routing, switching, 3G, WLAN, voice, & security functions. Open Service Platform The AR1200 interconnects with the third-party IT systems by using the Open Service Platform (OSP) to provide a unified communication solution for enterprise users. The customers, agents, third-party vendors, & manufacturers can develop & use the AR1200 as required. Outstanding Voice Experience The AR1200 provides various voice functions for enterprise data networks, enabling the enterprises to communicate flexibly & efficiently. Secure Service Access During service provision, the AR1200 ensures security of enterprise networks. It provides a complete security protection mechanism, including user access control, packet detection, & active attack defense. This mechanism protects customers' investments. Intelligent Service Deployment As the enterprise scale increases, enterprise users have high requirements on service deployment. The AR1200 provides USB (Universal Serial Bus) disk to deploy devices & auto-config function for service deployment. Simplified Service Management Enterprise users require simply service management. The AR1200 provides the i Tec, NQA, Net Stream functions to simplify service management. Applications & Benefits WAN Access The AR1200s function as the egress routers of enterprise branches & provide flexible access methods to support remote network connections. An AR1200 meets various access requirements, including leased line, Ethernet, x DSL, 3G, & WLAN. This saves deployment & maintenance costs & provides a large value to customers. High-Quality Voice Service As a voice gateway for enterprise networks, the AR1200 can function as an IP PBX or SIP gateway. The AR routers have built-in PBX, which supports the enterprise main number, IVR, & bill query functions to enhance corporate image & improve enterprise communication efficiency. The AR1200 is located in a branch to provide the intelligent dialing function. When a fault occurs on the WAN, the PSTN network is used as a backup for calls. When the SIP server at the headquarters is unreachable, the built-in local SIP server of the AR1200 implements communication between branches & communication between branch & PSTN network. This ensures reliability of the voice service. The AR1200 integrates voice, fax, & IP services. When providing voice services for enterprise users, the AR1200 functions as the SIP access gateway of a branch to transform phone signals into Vo IP signals. The AR1200 uplink interfaces are connected to the IMS/NGN network to allow any media including phones, handsets, & computers to communicate at any time. The AR1200 complies with 3G standards including CDMA2000 EV-DO, WCDMA, & TD-SCDMA, meeting the wireless communication requirements between branches & the headquarters. Users can use a 3G USB (Universal Serial Bus) disk to deploy 3G services on the AR1200, saving service card slots. In addition, the 3G data link can be used as a backup for wired link to protect the x DSL, FE/GE, & ISDN uplinks. The backup link improves network stability & reduces network construction costs. The AR1200 provides the NQA function to detect 3G link quality, ensuring the SLA. The AR1200 provides various secure access functions to implement communication between enterprise branches & between branches & the headquarters, & to enable partners to access enterprise resources. Tunnels such as GRE VPN & IPSEC VPN are set up between the headquarters & branches to implement secure data access & transmission. The AR1200 implements fast tunnel deployment & authentication for branches. Using a tunnel, partners can access & share enterprise resources.
