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
network.
