Cisco NM-8E1-IMA - 8-Port E1 ATM Network Module with Inverse Multiplexing over ATM (IMA) for Cisco 2600/3600/3700 Routers

Brand:

Cisco

Specifications

Product Overview:

The Cisco NM-8E1-IMA is a high-performance 8-Port E1 ATM Network Module that offers Inverse Multiplexing over ATM (IMA) for scalable and redundant WAN connectivity. Designed for Cisco 2600, 3600, and 3700 Series modular routers, this module is ideal for enterprises, service providers, and carriers requiring high-bandwidth ATM access over multiple E1 circuits.
Supporting up to 8 E1 links per IMA group, the NM-8E1-IMA aggregates multiple 2.048 Mbps E1 lines into a single logical high-speed connection. This increases throughput while improving fault tolerance—if one E1 link fails, traffic is redistributed across remaining active lines. With full compliance to ATM Forum IMA Version 1.1, it ensures seamless interoperability with telco-grade equipment and backbone infrastructures.
Whether you're building a high-availability WAN, supporting multi-service traffic, or connecting branch offices via ATM networks, the Cisco NM-8E1-IMA delivers unmatched performance, scalability, and resilience.
