Critical T3 errors - No ranging response received

I've upgraded to gig internet and my US/DS lights won't stop blinking. I'm getting lots of packet loss and late packets now too, and my modem log shows I'm getting a lot of T3 Time-outs. Any advice or solutions would be very much appreciated. Here's my event log if that helps (MAC removed)
