Troubleshooting 

•

 

All iMcV-E1-Mux/4 units are shipped configured as Host units via DIP 
Switch #1 = OFF. The Remote unit should be set to DIP Switch #1 = ON.  
Be sure to confirm that the iMcV-E1-Mux/4 card is set correctly when used. 

•

 

The fiber transport is independent of all other ports and should be 
established first.  If this is not possible, a physical fiber loopback can be used 
for fiber port verification.  A fiber loopback will cause all connected ports to 
loop back their respected data. 

•

 

If the fiber is not connected, all E1 ports will send the all-ones, 

AIS

 signal.  

This can be physically looped back to verify E1 port operation.
