3.14.1 Introduction

The Router 4-Port E1 IMA MIM interface card provides four E1 interfaces that support
inverse multiplexing for ATM (IMA) technology. The IMA technology is a method to
multiplex many low-speed links to one high-speed ATM cell flow: the transmission end
splits the cell flow of the ATM set to many low-speed E1 links, and the remote end
multiplexes these low-speed E1 links to one single cell flow. This technology is
cost-effective and flexible for application and mainly used in network applications that
transmit ATM cell through p
