The series uses the B-ISDN concepts as developed by ITU-T and conforms to theframework of Internation
35、al Standards for open systems interconnection as defined by ISO/IEC.This International Standard specifies the broadband connection oriented bearer services.This International Standard is based upon the practical experience of ECMA member companies and the results of their activeand continuous partic
36、ipation in the work of ISO/IEC JTC 1, ITU-T, ETSI and other international and national standardizationbodies. It represents a pragmatic and widely based consensus.The services specified in this International Standard are compatible with the equivalent services specified by the ATM Forumfor private A

39、ented bearer services is to guide and constrain thework on signalling protocols. Therefore, this International Standard is concerned mainly with the control aspects of services.Change of traffic characteristics during a call is outside the scope of this International Standard.Charging considerations
40、 are outside the scope of this International Standard.2 ConformanceIn order to conform to this International Standard, a protocol standard shall specify signalling protocols and equipmentbehaviour that are capable of being used in a B-PISN which supports the bearer service specified in this Internat

This means that, to claim conformance, a protocol standard is required to be adequate for the support of thoseaspects of clause 6 which are relevant to the interface or equipment to which the protocol standard applies.3 Normative referencesThe following standards contain provisions wh
