National bodies that are members of IS0 or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. IS0 and IEC technical committees col

38、laborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with IS0 and IEC, also take part in the work. In the field of information technology, IS0 and IEC have established a joint technical committee, ISO/IEC JTC I. Draft International S

39、tandards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote.

41、dard is one of a series of International Standards defining services and signalling protocols applicable to Broadband Private Integrated Services Networks (B-PISNs). The series uses B-ISDN concepts as developed by ITU-T and conforms to the framework of International Standards for Open Systems Interc

42、onnection as defined by ISO/IEC. This particular International Standard specifies the signalling protocol for use at the Q reference point for basic call/connection control (B-QSIG-BC). ix INTERNATIONAL STANDARD 0 ISO/IEC ISO/IEC 13247:1997(E) Information technology - Telecommunications and informat

43、ion exchange between systems - Broadband Private Integrated Services Network - Inter-exchange signalling protocol - Basic call/connection control 1 Scope This International Standard defines the signalling protocol for the purpose of basic call/connection control at the Q reference point between Priv

44、ate Integrated Services Network Exchanges (PINXs) connected together within a Broadband Private Integrated Services Network (B-PISN) employing Asynchronous Transfer Mode (ATM). This International Standard is part of the B-QSIG signalling system. The Q reference point is defined in ISO/IEC 11579- 1.

45、This International Standard is an application of the signalling protocol that forms part of the ATM Forums PNNI 1.0 specification, which in turn is based on ITU-T Recommendation 4.2931, including the provisions for symmetrical operation described in annex H of recommendation 4.2931. Technical differ

46、ences compared with the signalling protocol specified in PNNI 1.0 are summarized in annex J. Guidelines for interworking between a network employing the signalling protocol specified in this International Standard and a network employing the ATM Forums PNNI 1.0 specification are given in annex L. Th

47、is International Standard is applicable to PINXs which interconnect to form a B-PISN using static hop-by-hop routeing. It therefore complements the ATM Forums PNNI I.0 specification, which is applicable to networks that employ dynamic source routeing. The basic capabilities supported by the protocol

48、 specified in this International Standard are listed below and described in more detail in annex F: - demand (switched) virtual channel and virtual path connections; - point-to-point switched virtual channel and virtual path connections; - point-to-multipoint virtual channel connections; - connectio

49、ns with symmetric or asymmetric bandwidth requirements; - single-connection (point-to-point) calls; - basic signalling functions via protocol messages, information elements, and procedures; - CBR, VBR (realtime and non-realtime), UBR and ABR service categories; - negotiation of certain signalling parameters; - inter-PINX virtual channel identifier (IPVCI) negotiation; - out-of-band signalling for all signalling messages; - error recovery; - B-PISN addressing formats; - end-to-end compatibility parameter identification; - signalling interworking with N-PISN and provision of N-PISN services
