Multifunctional Interface Modules (Router 5000)

Step 2: Plug the DB-28 connector of the cable to the corresponding DB-28 port on the MIM card.

Step 3: Connect the other end of the cable as follows:

z

z

If the WAN is a DDN line, connect the cable to the port on the CSU/DSU.

If the WAN is a dialup line, connect the cable to the serial port of an analog modem.

Step 4: Power on the router, and check behavior of the LINK LED on the MIM panel. It is OFF when fault occurs on the line and signal is not synchronized. Check the line status.

3.8 Router 2 and 4-Port CE1/PRI MIM Modules

3.8.1Introduction

I.2 and 4-Port CE1/PRI

Router 2 and 4-Port CE1/PRI MIM, the 1-/2-/4-port channelized E1/PRI interface module, transmits, receives, and processes E1 data traffic. In addition, you can use the card for other purposes, such as CE1 access and the ISDN PRI function.

II.

The module is different from the 2 and 4-Port CE1/PRI module in the sense that:

zThe FE1 operating mode supported by the E1-F cards allows only one n x 64 kbps bundle to be formed on each interface, where n = 1 to 31. However, an E1 card allows arbitrary grouping of 31 channels and multiple bundles.

zThe E1-F modules do not support PRI mode.
