Recommendations T.2 and T.3 define Group 1 and Group 2 facsimile terminals respectively; such stand-alone terminals have not been manufactured for many years and Group 3 facsimile terminals are the only type being used on the GSTN.
In recognition of this market situation, Study Group 8 has agreed to delete references to Groups 1 and 2 in Recommendations T.4 and T.30.
In order to be consistent and to minimize the possibility of any confusion, it is proposed that this Recommendation be amended to delete references to Group 1 and Group 2 terminals and also to use consistent terminology.
