scope:

This standard is based on the 1988 Blue Book Recommendations Q.791 and Q.795 of SS7 for international use issued by the CCITT Study Group XI (Vol. VI, Fascicles VI.7 and VI.8) and is intended to be compatible with that standard. It has been modified for use within and between U.S. Networks to meet the anticipated needs and applications of those entities. In general, the modifications fall into two categories: 1) The specification of options designated by the CCITT for national use. 2) Extensions to the 1988 protocol to provide for new applications of the SS#7 protocol. This is in accordance with the current and projected ITU-T activity. This standard is intended for use in conjunction with ANSI T1.110-1992 on Signalling System Number 7 (SS7) - General Information, which includes an overview of SS7, a glossary, and a chapter on abbreviations. Formerly known as T1.116-2000(R2005).
