Rygar,

You are very far from the VRAD (2100-2500').  Your line is barely handling the 25 Mbps profile (bits in use = 98%).

The noise margin is in red because of the very small amount of overhead that your line has left.

You can probably stay on the 24 Mbps profile for now, but I would watch your bits in use very closely.  If it gets to 100%, your line may start taking errors, giving you picture freezes and pixelation.  If that happens, there will be no recourse except to lower the profile to 19/2.
