MIM-2E1/MIM-4E1/MIM-4E1-F modules

Introduction

• MIM-2E1/MIM-4E1

MIM-2E1/MIM-4E1, the 2-/4-port channelized E1/PRI interface module, transmits, receives, and

processes E1 data traffic. In addition, you can use the module for other purposes, such as CE1

access and the ISDN PRI function.

• MIM-4E1-F

The MIM-4E1-F module is different from the MIM-2E1/MIM-4E1 module in the sense that:

{ The FE1 operating mode supported by the E1-F modules allows only one n x 64 kbps bundle to

be formed on each interface, where n = 1 to 31. However, an E1 module allows arbitrary

grouping of 31 channels and multiple bundles.

{ The E1-F modules do not support PRI mode.
