PCI Accelerator Cards (PACs)

PCI Accelerator Cards (PACs) provide additional processing features or performance, but do not add extra physical interfaces to the router. A PAC can be installed in the dedicated PAC slot on AT-AR725 and AT-AR745 routers. The AR750S, AR750S-DP, and AR770S routers have an inbuilt high performance encryption processor, and therefore do not have a PAC slot.

!Warning PACs should only be installed by authorised service personnel. Unauthorised opening of the router’s lid may cause danger of injury from electric shock, damage to the router, and invalidation of the product warranty.

Two PACs are available:

AT-AR060 EPAC, Encryption PAC.

AT-AR061 ECPAC, Encryption/Compression PAC.

How PACs work PACs provide AR725 and AR745 routers with high performance hardware- based encryption and/or compression services. PACs have a DMA slave processor, which operates independently of the base system. This processor is responsible for the transfer of data between the base system and the PAC, and the control of local high speed encryption and compression data processing devices.

This architecture allows data encoding to be performed off-line without involving the base router processor, thereby maximising PAC performance while at the same time minimising impact on the router.

The PAC is a single card. Figure 19 shows the layout of the board for an

AR700 Series specifications

The Allied Telesis AR700 Series represents a robust line of edge routers engineered for high-performance networking. These devices are aimed at delivering versatility and scalability, catering to the needs of various organizations, whether small businesses or larger enterprises. Known for their reliability and advanced features, the AR700 Series stands out as a compelling option for organizations seeking to enhance their network infrastructure.

One of the standout features of the AR700 Series is its support for advanced routing protocols. The routers are capable of handling various protocols such as OSPF, BGP, and RIP, ensuring seamless integration within diverse network environments. This capability allows organizations to efficiently manage their routing needs, optimizing data flow for enhanced performance.

In addition to its routing protocols, the AR700 Series supports powerful Quality of Service (QoS) features. This technology prioritizes network traffic based on specific requirements, ensuring that vital applications receive the necessary bandwidth. This is particularly important for businesses that rely on real-time services such as video conferencing or voice over IP (VoIP), where uninterrupted service is critical.

The AR700 Series is also equipped with advanced security features to safeguard against cyber threats. With built-in firewall capabilities, VPN support, and traffic filtering, these routers help protect sensitive data from unauthorized access and attacks. Additionally, the ability to implement VLANs (Virtual Local Area Networks) further enhances the security and manageability of the network.

Scalability is a key characteristic of the AR700 Series. Organizations can easily expand their network capabilities as they grow, with support for various interface modules. This flexibility enables businesses to adapt their infrastructure without the need for complete overhauls, making it a cost-effective solution in the long run.

Management and monitoring of the AR700 Series are also streamlined, thanks to user-friendly interfaces and comprehensive management tools. IT teams can efficiently configure, monitor, and troubleshoot the network, ensuring optimal performance and reducing downtime.

In summary, the Allied Telesis AR700 Series routers combine advanced routing capabilities, robust security features, and scalable designs to meet the evolving needs of modern networks. With support for QoS, versatile protocols, and easy management, these devices are well-equipped to handle the demands of today's data-driven environments, making them an excellent choice for organizations aiming to improve their network performance and security.
