3.14 Router 4-Port E1 IMA MIM

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 plesiochronous digital hierarchy (PDH) network.
