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).

throughout the text of the notes).

and continuing to the heading for S 8.4.7 is part of Note 2 and should be
properly indented.

occurrence of a frame-rejection condition, the error-correcting entity shall
initiate re-establishment (see S 8.4.9.2) while an error-corrected condition is
