T.416 (1993)Kor.l (1997 E) 1 - STD-ITU-T RECMN T.4Lb CORR 1-ENGL 1997 48b2591 Ob45502 983 FOREWORD IT (International Telecommunication Union) is the United Nations Specialized Agen
5、cy in the field of telecommuni- cations. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a
6、worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics. The approval of Recommendations by the Members of the ITU-T is cover
7、ed by the procedure laid down in WTSC Resolution No. 1. In some areas of information technology which fall within ITU-T?s purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. NOTE In this Recommendation, the expression ?Administration? is used for conciseness to i
8、ndicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS The ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. The ITU takes no positio
9、n concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, the ITU had not received notice of intellectual property, prot
10、ected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database. O ITU 1998 All rights reserved.

It acts as a word delimiter and indica
44、tes a potential line break point except when it is immediately followed by another SPACE or by an occurrence of the control function NBH (No Break Here) (see 13.3.2). The graphic character SPACE specifies that the active position is to be advanced without a graphic symbol being imaged. However, any
45、graphic renditions that are in effect apply also to the graphic character SPACE, e.g. if underlining is in effect, an underline with no graphic symbol would result. Any SPACE graphic characters that follow a non-SPACE character and that precede a line terminator are ignored by the content imaging pr
