3、O/IEC 17310:2000 (first edition, 2000-09-15) has been adopted withoutmodification (IDT) as CSA Standard CAN/CSA-ISO/IEC 17310:04, which has been approved as a NationalStandard of Canada by the Standards Council of Canada.ISBN 1-55397-706-8 December 2004The Canadian Standards Association (CSA), under
4、 whose auspices this National Standard has been produced, was chartered in 1919 and accredited by the Standards Council of Canada to the National Standards system in 1973. It is a not-for-profit, nonstatutory, voluntary membership association engaged in standards development and certification activi
5、ties. CSA standards reflect a national consensus of producers and users including manufacturers, consumers, retailers, unions and professional organizations, and governmental agencies. The standards are used widely by industry and commerce and often adopted by municipal, provincial, and federal gove
6、rnments in their regulations, particularly in the fields of health, safety, building and construction, and the environment. Individuals, companies, and associations across Canada indicate their support for CSAs standards development by volunteering their time and skills to CSA Committee work and sup
7、porting the Associations objectives through sustaining memberships. The more than 7000 committee volunteers and the 2000 sustaining memberships together form CSAs total membership from which its Directors are chosen. Sustaining memberships represent a major source of income for CSAs standards develo
8、pment activities. The Association offers certification and testing services in support of and as an extension to its standards development activities. To ensure the integrity of its certification process, the Association regularly and continually audits and inspects products that bear the CSA Mark.
9、In addition to its head office and laboratory complex in Toronto, CSA has regional branch offices in major centres across Canada and inspection and testing agencies in eight countries. Since 1919, the Association has developed the necessary expertise to meet its corporate mission: CSA is an independ
10、ent service organization whose mission is to provide an open and effective forum for activities facilitating the exchange of goods and services through the use of standards, certification and related services to meet national and international needs.For further information on CSA services, write toC
11、anadian Standards Association5060 Spectrum Way, Suite 100Mississauga, Ontario, L4W 5N6CanadaThe Standards Council of Canada is the coordinating body of the National Standards system, a federation of independent, autonomous organizations working towards the further development and improvement of volu
12、ntary standardization in the national interest. The principal objects of the Council are to foster and promote voluntary standardization as a means of advancing the national economy, benefiting the health, safety, and welfare of the public, assisting and protecting the consumer, facilitating domesti
13、c and international trade, and furthering international cooperation in the field of standards. A National Standard of Canada is a standard which has been approved by the Standards Council of Canada and one which reflects a reasonable agreement among the views of a number of capable individuals whose
14、 collective interests provide to the greatest practicable extent a balance of representation of producers, users, consumers, and others with relevant interests, as may be appropriate to the subject in hand. It normally is a standard which is capable of making a significant and timely contribution to
15、 the national interest. Approval of a standard as a National Standard of Canada indicates that a standard conforms to the criteria and procedures established by the Standards Council of Canada. Approval does not refer to the technical content of the standard; this remains the continuing responsibili
16、ty of the accredited standards development organization. Those who have a need to apply standards are encouraged to use National Standards of Canada whenever practicable.

The
42、series uses the ISDN concepts as developed by ITU-T (formerly CCITT) and is also within theframework of standards for open systems interconnection as defined by ISO/IEC.This International Standard specifies mapping functions for the type of scenario where two PINXs are interconnected via a64 kbit/s
43、circuit mode connection with 16 kbit/s sub-multiplexing.This International Standard is based upon the practical experience of ECMA member companies and the results of their activeand continuous participation in the work of ISO/IEC JTC 1, ITU-T, ETSI and other international and national standardizati
44、onbodies. It represents a pragmatic and widely based consensus.INTERNATIONAL STANDARD ISO/IEC 17310:2000(E) ISO/IEC 2000 All rights reserved 1Information technology - Telecommunications and information exchange betweensystems - Private Integrated Services Network - Mapping functions for theemploymen
45、t of 64 kbit/s circuit mode connections with 16 kbit/s sub-multiplexing1ScopeThis International Standard defines the mapping functions in exchanges of Private Integrated Services Networks (PISNs)required for the utilization of scenarios in which 64 kbit/s circuit mode connections are sub-multiplexed
46、 into 4 x 16 kbit/schannels for carrying inter-PINX signalling and user information.NOTE 1 - This International Standard has been prepared to meet the specific needs of an application for a particular user organisation.However, it may also be applicable elsewhere. The requirements contained in this
47、International Standard will be incorporated in any futurestandard specifying a more generic approach to bearer conditioning.In order to connect a Private Integrated Services Network Exchange (PINX) to another PINX, mapping functions are requiredto adapt the specific interfaces at the C reference poi
48、nt to the application at the Q reference point. As such, mapping functionsprovide for physical adaptation to the interface at the C reference point. Mapping functions also provide for the mapping ofuser channels and signalling information at the Q reference point to the appropriate channels or times
49、lots at the C referencepoint.The C and Q reference points are defined in ISO/IEC 11579-1.The type of interface at the C reference point covered by this International Standard is the 64 kbit/s Unrestricted Digital LeasedLine (D64U) Terminal Equipment Interface, in accordance with ITU-T Rec. G.703.At the Q reference point the mapping provides a 16 kbit/s service for user channels to support the transfer of unrestricteddigital information and to support the transfer of speech, and a packet mode service fo
