I have a VWIC2-2MFT-T1/E1 card in a 3825 router. After a power outage it is no longer connecting. When the router is powered back up both ports on the T1 card have the Alarm light on even without any cable plugged in. Is this a configuration error or a hardware error? I have tried a loopback plug and am unable to get any change. I have also tried a new card and changing ports.
