Cisco (NM-4E1-IMA) Expansion Module

Multiport T1/E1 ATM network modules with Inverse Multiplexing over ATM (IMA) are available for both the Cisco 2600 and 3600 series multiservice access platforms. Available in both four- and eight-port versions, these multiport ATM modules allow service provider and enterprise customers to cost-effectively increase bandwidth, extending multiservice capabilities to remote-branch-office locations through ATM. ??These multiport T1/E1 ATM network modules with IMA add to the broad Cisco portfolio of customer premises equipment (CPE), ATM edge, and central-office products, that allow branch offices to take advantage of the higher bandwidth and multiservice capabilities available from ATM services. These new ATM modules complement the existing OC-3 and 25-Mbps family of ATM network modules available for the Cisco 2600 and 3600 series that now offer ATM bandwidth from 1.544-Mbps to 155-Mbps.
