No A/A1 on a dial Icm, only on line cards and the like (no hold on the ICM). The original Manual ICM (401A) needed an A lead, the later one (401B) didn't.
I'm trying to remember if the automatic tie line cards (415) needed an A lead. I could go downstairs dig through some boxes, find the BSPs or the GTEPs and find out, but I think I'll have a beer instead.
