> Why is AT&T, rather than my LEC, supplying ISDN service?

I think you might be confused about the different flavors of ISDN.

What AT&T is offering is PRI (primary rate interface) ISDN.  If your
company uses T1 PBX's then you'd buy ACCUNET T1.5 from them.  If it
uses ISDN PBX's, then you buy these ISDN lines.  This is all
point-to-point leased line stuff.

You are probably interested in BRI (basic rate interface) ISDN, a very
different animal.
