SCOPE AND PURPOSEThis Technical Report is a compilation of DSS1 codepoints that are defined for use
6、by ISDN supplementaryservices. No new information is contained herein since every DSS1 codepoint that is mentioned in this report hasalready been published in one or more American National Standards. Rather, this is a comprehensive listing ofcodepoints for ISDN supplementary services for the referen
7、ce of developers and other standards committees.Information contained herein is subject to change without notice since the development of new and revisedAmerican National Standards on ISDN supplementary services is an on-going activity.The information presented in this Technical Report includes modi
8、fications and extensions to DSS1 Layer 3messages, information elements, codepoints and timers defined for ISDN Supplementary Services that have beenpublished as American National Standards. Codepoints for basic call control (as presented in ANSI T1.607) andgeneric supplementary services procedures (
9、as presented in ANSI T1.610) are not contained in this TechnicalReport.If there are any discrepancies in information between this Technical Report and an American National Standardon an ISDN supplementary service, then the American National Standard shall take precedence.2.
