Yes, I'm on the North Carolina, and yes its a bit awkward using Japanese parts. However, its better than trying to restore the original 200 line switchgear, and then replacing brushes and lubing it weekly. Thanks for the advice, considering how often we lose power and brown-out I think I'll be better off cross-wiring one of the COs into the other box, etc. It makes the phone books weird because you need to know when to dial a 9 to get into the other switch. Plus, this way I can still use the one good 123210 I have working. Terry
