T3 Timeout and Packet Loss

I've opened up a case (CR903137276) but the person who originally contacted me has gone radio silent and is not responding to my emails.

 

I've noticed occasional network drops (random times). Looking at my modem I've seen my Upstream Power in the mid 50s. Checking logs I see hundreds of T3 Timeouts. Also seeing packet loss from the modem. Rebooting both the modem and my router doesn't seem to help.

 

I've replaced the splitter used by the modem and internet phone. I've replaced the CAT-5 between my router and the modem. Only thing I haven't replaced are the coax cables. Is there anything else I could check? It seems Comcast support is not helping much at the moment.
