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: Power on the Router, and check the LEDs of the corresponding slot on the 
front panel: ON means Router E1 Voice Module is operating normally and OFF means 
the POST of Router E1 Voice Module has failed. In the latter case, please contact your 
agent; 

Step 4: Check the status of the LINK LED on the Router E1 Voice Module panel. It is 
OFF when fault has occurred to the link. In this case, please check the link. 

3.3  Router T1 Voice Module 

3.3.1  Introduction 

Router T1 Voice Module can handle dense signals in VoIP systems. It can implement 
the VoIP function over T1 lines.   

Router T1 Voice Module is structured in the form of board plus daughter card. It 
provides a CT1/PRI port, allowing the access of 24 channels of voice signals. 

3.3.2  Appearance 

The appearance of Router T1 Voice Module is shown in the following figure:
