Figure 4: Dual-Port Multiflex T1 VWIC with Drop and Insert
The dual-port serial WICs feature the Cisco new, compact, high-density Smart Serial connector to support a wide
variety of electrical interfaceswhen used with the appropriate transition cables. Ports oneach card can be configured
individually to support a variety of synchronous or asynchronous protocols.

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,
yieldingdramatically higherthroughputand higherperformancethan asoftware-onlyimplementation. TheAIM 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.
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/BP supports a maximum number of 300 remote access
tunnels and a maximum of 800 remote access tunnels when using the Cisco 2600XM models. In comparison, the
