MIM-4E&M

Introduction

4-port voice E&M analog trunk interface module (MIM-4E&M) serves to access and handle 4 channels

of E&M analog trunks.

These modules make it possible to transfer voice signals over data communication networks.

Interface attributes

The interface attributes of MIM-4E&M modules are shown in the following table:
