ATIS 1000112.a.2006 (S2016)

This supplement to ATIS-1000112.2005 reassigns some of the subsystem number code points previously shown as spare to be ANSI Standard. These code points may be used to support applications which require internetwork messaging, but which do not qualify for international standardization. This addendum also provides the administrative procedures for requesting and assigning these subsystem number code points.
