ERRATA SHEET FOR BLUE BOOK VERSION                      August 1990
                   RECOMMENDATION V.42
                  FASCICLE VIII.1
                  IXth PLENARY ASSEMBLY OF THE CCITT
                   MELBOURNE, 1988

               Following the publication of Volume  VIII,  Fascicle  VIII.1  of  the  Blue
         Book, technical experts in Study Group XVII  discovered  a  number  of  editorial
         discrepancies in the text of Recommendation V.42. Some of  these  would  lead  to
         improper implementation if  the  text  were  precisely  followed.  The  technical
         experts have developed and submitted to the CCITT a  comprehensive  list  of  the
         necessary corrections. While these will be reflected in  the  published  text  at
         some future date, printing deadlines  did  not  permit  their  inclusion  in  the
         present version. The reader is kindly requested to take note of the errata  noted
         below while considering the content of Recommendation V.42 (only the  technically
         significant corrections are noted in this document).
