This attribute, if set to a value of allowed indicates that incoming
international normal charged calls (from the network to the DTE)
can be made to this Dna. If set to a value of disallowed, then such
calls cannot be made to this Dna - such calls will be cleared by the
local DCE.
This attribute also currently controls access to/from the E.164
numbering plan, and if set to a value of allowed, then cross-
numbering plan calls (also normal charged) are allowed.
This attribute is ignored if the corresponding attribute, incCalls is
set to a value of disallowed.
