• Intelligent call routing, ensuring high reliability of voice services
• Interconnection with the NGN/IMS/PBX/terminal of mainstream vendors
• QoE, detecting voice service quality in real time
• Jitter buffer, echo cancellation, and packet loss compensation, improving customer experiences

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, and active attack defense. This mechanism protects customers' investments.

• Built-in firewall
• Authentication technologies on ports, such as 802.1x authentication, MAC address authentication, and portal authentication
• Authentication methods, including RADIUS and HWTACACS
• VPN technologies, including IPSec VPN, GRE VPN, DSVPN and SSL VPN

Intelligent Service Deployment

As the enterprise scale increases, enterprise users have high requirements on service deployment. The AR1200 provides the following service deployment functions:

• The AR1200 provides a mini-USB port. By using the mini-USB, users can configure the devices through GUI.
• Users can use the USB disk to deploy devices, and the devices are plug-and-play.
• The AR1200 supports the auto-config function. The auto-config function enables the AR1200 to automatically obtain configurations.

Simplified Service Management

Enterprise users require simply service management. The AR1200 provides the following functions to simplify service management:

• The AR1200 works with the eSight network management system to simplify device management.
• The AR1200 provides the NQA function to monitor links in real time.
• By using the NetStream function provided by the AR1200, users can view traffic characteristics and statistics clearly, which is basis for network optimization.

1 WAN Access

The AR1200 functions as the egress routers of enterprise branches and provide flexible access methods to support remote network connections. AR1200 meets various access requirements, including leased line, Ethernet, xDSL, 3G, and WLAN. This saves deployment and maintenance costs and provides a large value to 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 30 W power, ensuring power for large-power PDs.

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. 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. And also the AR1200 can be located in a branch to provide the intelligent dialing function.

Figure 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.

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 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.

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, IPSEC VPN, DSVPN and SSL 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.

**Note: The maximum number of slots includes the number of combined slots.

Before choosing an AR1200, determine the device model, interface cards, and software configurations.

Device model and main control board

• The device model is determined by the slot quantity and forwarding capacity that you require.

Service card

• The interface cards, including SIC cards and WSIC cards, are inserted into service card slots. Two SIC slots can be combined into one WSIC slot by removing the guide rail.

Software

• The basic software and licensed software are available. The basic software provides basic functions such as routing, switching, voice, and security. The licensed software provides additional functions such as PBX.
