Advanced Integration Module Options

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

function-specific hardware to off-load 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’s resources, including the main system bus. The TDM bus and the serial

communications controllers make this a very flexible and powerful feature. Since the AIM is internally mounted,

external slots remain available for integration of other modular components such as CSU/DSUs, WAN interfaces,

or other devices such as modems, or packetized voice/fax processors.

The Data Compression AIM provides a cost-effective option for reducing recurring WAN costs and maximizes the

benefit of the advanced bandwidth management features of the Cisco IOS software. With compression ratios of up

to 4:1, the Data Compression AIM supports 8Mbps of compressed data throughput without imposing additional

traffic latency—enough to keep two T1 or E1 circuits full of compressed data in both directions simultaneously.

The Data Compression AIM supports industry standard LZS and Microsoft Point-to-Point Compression (MPPC)

algorithms and ensures compatibility with all Cisco products supporting hardware- or software-based compression.

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 new AIM-VPN/BPII and AIM-VPN/EPII supports a

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

accelerated DES/3DES and the new AES (Advanced Encryption standard) encryption at speeds up to 80-Mbps

performance (max based on 1400 byte packet size). In addition the AIM-VPN/BPII and AIM-VPN/EPII support

hardware-assisted layer-3 compression services where bandwidth conservation may lower network connection costs.

The new AIM-ATM provides a high-performance hardware-based ATM access solution for one to four T1 or E1

connections supported by the T1 or E1 VWICs (for example, VWIC-IMFT-T1). This frees the network module slot

to support other functions. When used in combination with a high density voice network module (NM-HDV-xxx),

the ATM AIM supports ATM adaptation layer (AAL) 2 and AAL5 VoATM. In addition, the new ATM-VOICE-30

and ATM-ATM-VOICE-30 AIMs provides a cost effective solution for supporting voice services or digital voice over

ATM (AAL2 and AAL5) support, without the use of a network module.
