Chapter 4 
Troubleshooting 

This chapter provides frequently asked questions as identified from 
Digium Technical Support and possible resolutions. Multiple resources 
are available to obtain more information about Asterisk and Digium 
products. These resources are listed on page 47. 

What do the Status LED colors indicate? 

„

Green - Card is in-sync with the far end. 

„

Red - Card is not seeing far end, circuit is not up, or cable is bad. 

What type of cable do I need? 

In all cases, you can use a straight-through, standard RJ-45 Ethernet cable 
going from the NT unit to the B410P. When you put the card in NT mode 
with the correct jumpers, the pins will automatically swap as seen in the 
following example. 

Pin 3 <-> Pin 4  
Pin 5 <-> Pin 6
