The card I have is in a 3845 router. The card is a NM1-T3/E3 DS3 card that has transmit and receive coax connections. The card is in the router and the green light is on solid for enable. When I look for the interface on the router it is not there. I assume this is because there is currently no cables connected to it. I would like to get a basic configuration for this as it is being connected to AT&T for our WAN interface.
I have this problem too.
