A cabinet full of SLIBC cards? That sounds like a power supply's recipe for disaster, especially if they have message waiting modules on them. Yes, the ring generator also needs to be upsized from the little (3073-00) one to the bigger external one (3073-10). I don't see a time slot issue, so I'm pretty sure that it's a power supply or ring generator issue.
