The AIM-ATM optimizes the Cisco 2600, 2600XM, 2691, 3660, and Cisco 3700 Series modular multiservice routers by offering ATM adaptation layer 2 (AAL2) and ATM adaptation layer 5 (AAL5) support for low-density T1/E1 data and voice connections over ATM networks. This AIM module allows service providers and enterprise customers to take advantage of the reliability and quality of service (QoS) available with ATM connectivity. This AIM module provides a cost-effective option for reducing recurring cost and maximizing the benefits of the advanced bandwidth management features of the Cisco IOS software. This AIM module take advantage of the internal AIM slot(s) of the Cisco 2600, 2600XM, 2691, 3660, and 3700 series routers, ensuring that external slots remain available for components such as WAN interface network modules, and serial WAN network modules.
By supporting CPU-intensive applications such as ATM or voice services on a dedicated coprocessor, users can obtain significantly higher throughput rates and enable new services and applications.
