120 CHAPTER 3: MULTIFUNCTIONAL INTERFACE MODULES
■ Read the mark identifying a port before you connect a cable to it, making sure
it is the correct port. Wrong connection tends to damage the MIM and even
the Router.
Step 1: Plug the DB-15 connector of the cable into the DB-15 port on the
MIM-2VE1 module and fasten the screws;
Step 2: Connect the RJ-45 connector of the cable to:
■ The peer device directly, if the resistance of the port to be connected is
120-ohm, and there is no need to extend the cable;
■ A network interface connector and then the peer device using another E1
120-ohm balanced twisted pair cable, if the resistance of the port to be
connected is 120-ohm, and there is a need to extend the cable, as illustrated in
the following figure.
Figure 136 Extending E1 120-ohm balanced twisted pair cable
■ The peer device using a 75ohm-to-120ohm adapter, if the resistance of the
peer device is 75-ohm;
Step 3: Check the behavior of the LINK LED on the MIM-2VE1 panel. It is OFF
when fault has occurred on the link. In this case, please check the link.
MIM-2VT1 Module
Introduction 2-port T1 voice interface module (MIM-2VT1) can handle dense voice signals in
VoIP system. It provides two CT1/PRI/ ports, allowing the access of 48 channels of
voice signals.
