I wouldn't think it would be larger than the T-1 level or you'd be having a lot more problems, especially on data. If the only common thing is the 5E that's where I'd look. Anthony, when a 5E is used for a tandem switch it's slaved off the master clock isn't it? Don't know how you could have two 5E's in tandem with both suppling clock. I'm sure it would be at the T-1 level in the DTU (maybe not the right term for the T-1 cards)
