MIM-1VT1 Module 125
■ 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.

■ 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-1VE1 panel. It is OFF
when fault has occurred on the link. In this case, please check the link.
MIM-1VT1 Module
Introduction 1-port T1 voice interface module (MIM-1VT1) can handle dense voice signals in
VoIP system.
MIM-1VT1 module is structured in the form of board plus VCPM card plus VPM
strip. It provides a CT1/PRI port, allowing the access of 24 channels of voice
signals.
