Huawei AR3200 series enterprise routers (AR3200) are next-generation enterprise-class routers based on the Huawei proprietary Versatile Routing Platform (VRP), which take advantage of Huawei long-term accumulation in data communication, wireless, access network, and core network fields. The AR3200 integrates routing, switching, 3G, voice, and security functions. It uses a multi-core CPU and non-blocking switching structure that provides industry-leading system performance, meeting service development requirements both now and in the future. The AR3200 provides an integrated solution for enterprise networks, speeds up multi-service provision, and protects customers' investments.

**Note that there're two kinds of main control boards for the AR3260, SRU40 and SRU80 (Serive and Router Unit). The SRU40 provides 2Mpps packet forwarding performance and SRU80 can provide 4Mpps packet forwarding performance and hardware-based TM(Traffic Management) function. SRU80 support hardware-based HQos function.

The AR3200 supports various interface cards, including Ethernet interface cards, E1/T1/PRI/VE1 interface cards, synchronous/asynchronous interface cards, ADSL2+/G.SHDSL interface cards, FXS/FXO voice cards, ISDN interface cards, CPOS interface cards and EPON/GPON interface cards. The cards can be classified into SIC (Smart Interface Card) cards, WSIC (Double-Width SIC) cards, and XSIC (Double-Height WSIC) cards depending on slot type.

3 Services Integrated on One Router

The AR3200 integrates routing, switching, 3G, voice, and security functions.

Open Service Platform

The AR3200 interconnects with the mainstream 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, and manufacturers can develop and use the AR3200 as required.

• Fast service integration and customization, meeting customized requirements
• Service integration without deploying dedicated servers, saving investments and simplifying management
• Services synchronized with cloud-side services, local services processed locally, which improves service quality and efficiency.

Outstanding Voice Experience

The AR3200 provides various voice functions for enterprise data networks, enabling the enterprises to communicate flexibly and efficiently.

• Basic voice functions provided by the built-in PBX, SIP server, and SIP access gateway
• Value-added voice services, including multi-party communication, IVR automatic connection, ring-back-tone, parallel ringing, sequential ringing, one number link you (ONLY), bill management, and subscriber management
• 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

Security

During service provision, the AR3200 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, L2TP VPN and SSL VPN

Intelligent Service Deployment

As the enterprise scale increases, enterprise users have high requirements on service deployment. The AR3200 provides the following service deployment functions:

• The AR3200 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 AR3200 supports the auto-config function. The auto-config function enables the AR3200 to automatically obtain configurations.

Simplified Service Management

Enterprise users require simply service management. The AR3200 provides the following functions to simplify service management:

• The AR3200 works with the eSight network management system to simplify device management.
• The AR3200 provides the NQA function to monitor links in real time.
• By using the NetStream function provided by the AR3200, users can view traffic characteristics and statistics clearly, which is basis for network optimization.

1 High-Density Ethernet Access

The AR3200 provides 24GE interface cards to implement high-density GE access. This interface card facilitates network operation and maintenance and protects customers' investment.

2 High-Quality Voice Service

As a voice gateway for enterprise networks, the AR3200 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 AR3200 integrates voice, fax, and IP services. When providing voice services for enterprise users, the AR3200 functions as the SIP access gateway of a branch to transform phone signals into VoIP signals. The AR3200 uplink interfaces are connected to the IMS/NGN network to allow any media including phones, handsets, and computers to communicate at any time.

3 VPN in Branch

Figure 1. VPN over the Internet

The AR3200 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, L2TP VPN and SSL VPN are set up between the headquarters and branches to implement secure data access and transmission. The AR3200 implements fast tunnel deployment and authentication for branches. Using a tunnel, partners can access and share enterprise resources. The AR3200 provides authentication and authorization for users.

Figure 2. VPN over the MPLS network

As the PEs of an MPLS network, the AR3200s are located in the enterprise headquarters and branches. Different types of services are separated by MPLS L3 VPN. The AR3200 implements flexible deployment, fast distribution, and secure transmission of VPN services, and supports enterprise service operation over networks.

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

Before choosing an AR3200, determine the device model, main control board, service cards, and software configurations.

Device Model and Main Control Board

• The device model and main control board are determined by the slot quantity and forwarding capacity that you require.

Service Card

The AR3200 service cards are classified into interface cards and DSP cards. The interface cards, including SIC cards, WSIC cards, and XSIC cards, are inserted into service card slots. Two SIC slots can be combined into one WSIC slot by removing the guide rail, and two WSIC slots can be combined into one XSIC slot by removing the panel. The DSP card is inserted into the DSP slot and works together with the FXO/FXS/ISDN/VE1 voice card.

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.
