Hello,
Been struggling for months now to resurrect my MMI to no avail. I have put fiber loopbacks in front of the amp, sat, and radio pieces which hasn't changed the results at all. At this point, I'm looking to see if anyone has any fiber routing diagrams. I know where most of the pieces are, but don't know how the fiber routes. I have 8 devices that can't be reached, and 6F-Centr. Conv. II with a status of Malfunction.

Major problem:

I have this but it might be a logical diagram.
