For more information, please visit .AMERICAN NATIONAL STANDARD Approval of an American National Standard requires review by ANSI that the re
6、quirements for due process, consensus, and other criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agr
7、eement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made towards their resolution. The use of American National Standards is completely voluntary; their existence does not in any
8、respect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an int

30、 Network (ISDN)- Signaling Specification for X.25 Packet-Switched Bearer Service for Digital Subscriber Signaling System Number 1 (DSSI) 1 Scope, purpose, and application 1 .l Purpose This interface standard was written to provide a set of requirements for user-network signal- ing for ISDN support o
31、f packetized data trans- fer, while conforming, wherever possible, with the I-Series Recommendations of the International Telegraph and Telephone Consultative Committee (CCITT), and while not compromising the principles of evolution expressed therein. Equipment may be imple- mented with additional f
32、unctions and proce- dures. This standard presents the procedures at the S, T, or U reference point for B-channel, and D-channel access connection on basic rate interfaces and primary rate interfaces to a Packet-Handling (PH) function within the Integrated Services Digital Network (ISDN) to support I
33、SDN virtual circuit service. Procedures at the S, T, or U reference point for B-channel access to a Packet-Switched Public Data Network (PSPDN) are also speci- fied. 1.2 Scope The scope of this standard covers the follow- ing procedures at the S, T, or U reference point: a) Circuit-switched access t
34、o Packet- Switched Public Data Network (PSPDN) ser- vices - case A. This standard defines the use of the proce- dures of ANSI T1.602 and ANSI T1.607, when appropriate, on basic rate interfaces and primary rate interfaces for the establish- ment and release of circuit-switched calls through ISDN to t
35、he access port of PSPDN. These circuit-switched calls may be initiated by the user or the access port of PSPDN. Only the B-channel is used in this instance; b) Packet-switched access to an ISDN vir- tual circuit service - case B. This standard defines the use of the proce- dures of ANSI T1.602 and A
36、NSI T1.607, when appropriate, on basic rate interfaces and primary rate interfaces for the establish- ment and release of packet-mode access connections to a packet-handling (PH) func- tion provided within the ISDN. These pack- et-mode access connections may be initiat- ed by the user or the Pl! fun
37、ction within the ISDN. B-channels and D-channels may be used in this instance; c) X.25 LAPB procedures on the B-channel and LAPD procedures on the D-channel, as described in ANSI T1.602. X.25 LAP proce- dures are not supported in this standard; d) X.25 packet level procedures on B-chan- nels and D-c
38、hannels. NOTE - Alternative methods of access via any bearer channel to Packet-Switched Public Data Networks are for further study. 1 ANSI T1.608-1991 1.3 Structure Clause 1 describes the purpose, scope, and structure of this document. Clause 2 lists ref- erence documents. Clause 3 lists definitions
39、 helpful in interpreting the specifications. Clause 4 provides an overview of packet- mode call control and defines the control states for case A circuit-switched calls and case B packet-mode access connections. Clause 5 specifies the message functional definitions. Clause 6 specifies the message st
40、ructure for case A circuit-switched calls and case B packet-mode access connections. Clause 7 specifies the procedures for packet communication at the S, T, or U reference point. Clause 8 specifies the system parame- ters. 2 Normative references l) The following standards contain provisions which, t
