Those are the signals levels from a cable modem, not the set-top box itself. You can find the status of box itself by using the hidden diag menus.

The OOB status is important because it could be that something died on your box and it can no longer communicate properly to request VOD. I've seen this happen before. Another symptom is that the guide data will slowly age out and not be replaced with newer data since OOB tuning isn't working properly.
BTW the proper model number is Motorola DCT-2244, which is a very old box that's been recycled again and again over the last 10+ years. So it wouldn't be a total surprise if it was defective.
