Cisco NM-4E1-IMA: 4-port E1 ATM network module with Inverse Multiplexing over ATM (IMA).

The Cisco NM-4E1-IMA is a 4-port E1 ATM network module with Inverse Multiplexing over ATM (IMA), fitted into the network-module slot of Cisco 2600, 3600 and 3700 series routers. IMA bonds multiple E1 links together into a single logical higher-bandwidth ATM connection, which was a common way to build WAN links beyond a single E1’s 2Mbps capacity before Ethernet-based WAN access became standard.

This module remains in service on legacy WAN edge routers still connected via bonded E1/ATM circuits, particularly in regions or networks where E1-based access was never migrated to Ethernet. Confirm the host router’s network-module slot type and IOS feature set (ATM/IMA support) before ordering, since not every 2600/3600/3700 chassis variant carries a compatible slot.
