3、tbetween a PINX and anInterconnecting Network.Brief HistoryThis Standard is one of a series of ECMA Standards defining services and signalling protocols applicable to PrivateIntegrated Services Networks (PISNs). The series uses ISDN concepts as developed by ITU-T and conforms to theframework of Inte
4、rnational Standards for Open Systems Interconnection as defined by ISO/IEC. It has been producedunder ETSI work item DEN/ECMA-00213.This Standard specifies the functional profile for interconnecting Private Integrated services Network eXchanges(PINX) to VPN service centers to permit interoperability
5、 between equipment from different vendors and serviceproviders.This Standard is based upon the practical experience of ECMA member companies and the results of their active andcontinuous participation in the work of ISO/IEC JTC1, ITU-T, ETSI and other international and regionalstandardization bodies
6、. It represents a pragmatic and widely based consensus.This ECMA Standard is contributed to ISO/IEC JTC1 under the terms of the fast-track procedure, for adoption as anISO/IEC International Standard. Thereafter it is proposed to ETSI for endorsement as an EN by means of the OneStep Approval Procedur
7、e (OAP).This ECMA Standard has been adopted by the General Assembly of December 2000.- i -Table of contents1Scope 12 Conformance 13 References (normative) 13.1 References of general significance 23.2 References to supplementary services and ANFs 34 Definitions 34.1 External definitions 34.2 Intercon

15、llingcapabilities at interfaces at the C reference point between a Private Integrated services Network eXchange(PINX) and an Interconnecting Network (ICN) to permit interoperability between equipment from differentvendors and different public or private service providers.NOTE 1PINX in the sense of t
16、his Standard is used in the meaning of a PINX directly attached to the ICN.This Standard is applicable to attached PINXs and Interconnecting Networks (ICN).This Standard identifies the necessary or optional employment of particular functions, procedures andservices when provided:- physical and elect
17、rical characteristics (physical layer) of the interfaces to the transmission systems to beemployed;- data link layer procedures;- network layer procedures; and- supplementary services and additional network features to meet specific corporate network userrequirements.This Standard states requirement
18、s upon attached PINXs and Interconnecting Network (ICN) implementationsin order to achieve interoperability between equipment in PISNs serving as Corporate telecommunicationNetworks (CNs).NOTE 2Implementation of this Standard does not preclude a manufacturer from offering other means ofinterconnecti
19、on. It also does not preclude a VPN service provider to offer basic call communications betweena PINX and other networks like PSTN or ISDN.ISO/IEC TR 14475 specifies various access arrangements between a PINX and a public network wherereference points C and T reside either at a single or at separate
20、 interfaces. The scope of this Standard islimited to cover the C reference point aspects at a separate interface.The current version of this Standard does not intend to specify any gateway or end PINX requirements for theICN side of the interface. Therefore it typically uses the term “virtual transi
21、t PINX“ instead of InterconnectingNetwork (ICN).2 ConformanceA system conforms to this Standard if it correctly performs all the mandatory capabilities defined in therequirement list (RL) (annex A) and the profile specific ICS (annex B).NOTE 3For the purpose of this Standard capabilities marked as o
22、ptional in the base standards may be mandatory orexcluded.3 References (normative)The following standards contain provisions which, through reference in this text, constitute provisions of thisStandard.
