Figure 5. Dual-Port Multiflex T1 VWIC with Drop and Insert

The dual-port serial WICs feature the new Cisco compact, high-density smart serial connector to support a wide variety of electrical interfaces when

used with the appropriate transition cables. Ports on each card can be configured individually to support a variety of synchronous or asynchronous

protocols.

AIM Options

All Cisco 2600 Series routers are equipped with an internal slot to support one or two field-installable AIMs. AIMs use function-specific hardware

to offload the main router CPU and accelerate processor- or resource-intensive services, yielding dramatically higher throughput and higher

performance than a software-only implementation. The AIM slot has access to virtually all of the router resources, including the main system bus.

The TDM bus and the serial communications controllers make this a very flexible and powerful feature. Because the AIM is internally mounted,

external slots remain available for integration of other modular components such as CSUs and DSUs, WAN interfaces, or other devices such as

modems or packetized voice and fax processors.

For example, the data encryption AIM offloads encryption processing from the Cisco 2600 Series CPU, providing 10 times the performance over

software-only encryption. The AIM-VPN/BPII, new AIM-VPN/BPII_PLUS-PLUS, AIM-VPN/EPII, and new AIM-VPN/EPII-PLUS support a

maximum number of 800 remote access tunnels when using the Cisco 2600 models. These modules offer hardware-accelerated Digital Encryption

Standard (DES) and Triple DES (3DES) and the new AES encryption at speeds up to 80-Mbps performance (maximum based on 1400-byte packet

size). In addition, these modules support hardware-assisted Layer 3 compression services, allowing bandwidth conservation for lower network

connection costs, with the new AIM-VPN/BPII_PLUS-PLUS and AIM-VPN/EPII-PLUS providing cryptographic-optimized wide key AES support

(192 and 256).
