According to _Notes on the BOC Intra-LATA Networks -- 1986_,
TR-NPL-000275, Issue 1, April 1986 (the most recent version of
_Notes_), 1+NPA-NXX-XXXX is either a "Permissive procedure.  May be
permitted in addition to recommended procedure" or a "Recommended
procedure" for all types of calls.  This includes locations with or
without non-common control switching systems (e.g.SXS); local-direct
dialed, toll-direct dialed, Home NPA, Foreign NPA, with or without
interchangeable CO codes.

Go figure.  It's that "may" that leaves room for interpretation.
