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.
