1.2.3 Services Integrated on One Router The AR1200 integrates routing, switching, 3G, WLAN, voice, and security functions.
Open Service Platform Outstanding Voice Experience Secure Service Access 1.3 Typical Application 1.3.1 WAN Access
The AR1200 functions as the egress routers of enterprise branches and provide flexible access methods to support remote network connections. It meets various access requirements, including leased line, Ethernet, xDSL, 3G, and WLAN. This saves deployment and maintenance costs and provides great value for customers. The fixed 100M Ethernet interfaces of AR1220V, AR1220W and AR1220VW support the PoE function in compliance with IEEE 802.3af and 802.3at; therefore, the AR1220V, AR1220W and AR1220VW can provide power for powered devices (PDs), such as IP phones. An 802.3at interface provides more than 30W power, ensuring power for large-power PDs.1.3.2 High-Quality Voice Service As a voice gateway for enterprise networks, the AR1200 can function as an IP PBX or SIP gateway.
Figure 1-1 IP PBX application
The AR routers have built-in PBX, which supports the enterprise main number, IVR, and bill query functions to enhance corporate image and improve enterprise communication efficiency. Also, the AR1200 can be located in a branch to provide the intelligent dialing function.Figure 1-2 SIP gateway application
The AR1200 integrates voice, fax, and 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 VoIP signals. The AR1200 uplink interfaces are connected to the IMS/NGN network to allow any media including phones, handsets, and computers to communicate at any time.1.3.3 3G Wireless Access in Branch
The AR1200 complies with 3G standards including CDMA2000 EV-DO, WCDMA, and TD-SCDMA, meeting the wireless communication requirements between branches and the headquarters. Users can use a 3G USB 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 a wired link to protect the xDSL, FE/GE, and ISDN uplinks. The backup link improves network stability and reduces network construction costs. The AR1200 provides the NQA function to detect 3G link quality, ensuring the SLA.1.3.4 VPN in Branch
The AR1200 provides various secure access functions to implement communication between enterprise branches and between branches and the headquarters, and to enable partners to access enterprise resources. Tunnels such as GRE VPN and IPSEC VPN are set up between the headquarters and branches to implement secure data access and transmission. The AR1200 implements fast tunnel deployment and authentication for branches. Using a tunnel, partners can access and share enterprise resources.1.4 Technical Specifications
