3、TIONAL STANDARD Approval of an American National Standard requires review by ANSI that the requirements 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, substant

4、ial agreement has been reached by directly and materially affected interests. Substantial agreement 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

14、TIS-0326600.2005 ii FOREWORD The information contained in this Foreword is not part of this American National Standard (ANS) and has not been processed in accordance with ANSIs requirements for an ANS. As such, this Foreword may contain material that has not been subjected to public review or a cons

15、ensus process. In addition, it does not contain requirements necessary for conformance to the Standard. The Alliance for Telecommunication Industry Solutions (ATIS) serves the public through improved understanding between carriers, customers, and manufacturers. The Telecom Management and Operations

16、Committee (TMOC) - formerly T1M1 -develops operations, administration, maintenance and provisioning standards, and other documentation related to Operations Support System (OSS) and Network Element (NE) functions and interfaces for communications networks - with an emphasis on standards development

17、related to U.S.A. communication networks in coordination with the development of international standards. This document is entitled Structure for the Identification of Telecommunications Circuits for Information Exchange. This American National Standard provides the code and format structures necess

18、ary for identification of telecommunications circuits. This standard contains clauses that cover its purpose and scope and that describe data units and format structures for representing message trunks and message trunk groups and for special services circuits. The code structure and format portion

19、of this standard is compatible with the CLCITM-MSG and CLCITM-S/S code designs for the identification of circuits. The CLCI-MSG and CLCI-S/S codes have been recognized as de facto telecommunications industry standards for the interchange of information for the provisioning and maintenance of circuit

20、s. Requirements are designated by the word shall, while recommendations use the word should. Requirements specify the minimum format and structure of codes required for information exchange between telecommunications service providers. This standard is intended for use in conjunction with standards

21、T1.251-2001 (Version Two), Service Provider Identification Codes, and T1.253-1999, Information Interchange - Code description and Codes for the Identification of Location Entities for the North American Telecommunications System.

ATIS-0326600.2005 2 3.2 data: A representation of facts, concepts, or instructions that are collected, organized, recorded, processed, and stored in a retrievable form suitable for communication, interpretation, or proc

26、essing by human or automated means. This definition refers to a group of facts taken as a unit; thus it is used with a singular verb. 3.3 data composite: A collection of data elements treated as a unit. 3.4 data element: A single unit of data that in a certain context is considered indivisible. It c

27、annot be decomposed into more fundamental segments of data that have useful meanings within the business. 3.5 data unit: A single kind of data for which the identification and description are identical for all occurrences. It may be a data element or a data composite. 3.6 format structure: A combina

28、tion of data units grouped in a prescribed sequence. 3.7 leg: A loop termination of a multipoint circuit that links a bridge to the end user location. 3.8 World Zone 1: Multiple countries which have an integrated numbering plan with the Country Code value “1”, as per ITU-T Rec. E.164. 4 GENERAL Each

29、 data element shall consist of sequences of characters, each character being either an alphabetic (A-Z) or numeric (0-9). (See 6.2.1, 6.2.2, and 6.2.3 for additional requirements for symbols.) In the format structures of clause 6, character positions that require alphabetic, numeric or either alphab

30、etic or numeric characters are represented by “A”, “N” and “A/N” respectively. The alphabetic characters shall be considered as case insensitive; that is, there shall be no distinction made between upper and lower case letters. However, it is recommended that the code be represented with upper case

31、letters. 5 DATA UNITS Clause 5 of this standard describes data elements and data composites that are used to construct the message trunk and special services circuit identification code formats of clause 6. 5.1 Message trunk data units 5.1.1 Trunk number A serial number type code that identifies a s

32、pecific trunk in a trunk group. This data element shall consist of one to four numeric characters. 5.1.2 Traffic class code A standardized code that designates an engineering categorization - e.g., grade of service, alternate route. This data element consists of two alphabetic characters. 5.1.3 Offi

33、ce class code A standardized code that designates the highest level of switching performed by the traffic units or offices terminating the trunk or trunk group - e.g., grade of service, alternate route.

34、here each character may be alphabetic or numeric. ATIS-0326600.2005 3 5.1.4 Traffic use code A standardized code that designates the type of traffic offered to the trunk group - e.g., inter-end office, tandem access, directory assistance. This data element consists of two alphabetic characters. 5.1.

35、5 Trunk-type modifier code A standardized code that indicates specialized use of the trunk or trunk group - i.e., only a portion of traffic, or enhanced information, is carried over the trunk or trunk group, such as coin, non-coin, bit rate. This data element consists of one to seven characters, eac

36、h of which may be alphabetic or numeric. 5.1.6 Location A code A standardized code that uniquely identifies the location of facility terminal A (i.e., lower in alphabetic sequence of the two facility terminal location codes), which is the telecommunications service company site at which equipment or

37、 personnel are located, the function of equipment or personnel at the site, or a customers presence at a location at which network elements or network systems equipment exists. This data composite shall consist of eleven characters, as allowed by the requirements of T1.253-1999. Complete definition

38、of this data composite may be found in T1.253-1999. 5.1.7 Location Z code A standardized code that uniquely identifies the location of facility terminal Z (i.e., higher in alphabetic sequence of the two facility terminal location codes, for which the description is equivalent to that of the Location

39、 A Code in 5.1.6). 5.1.8 Address signaling code A standardized code that designates the type of signals used to direct a call to its destination - e.g., multifrequency, common channel signaling, switching system 7. This data element consists of two characters, each of which may be alphabetic or nume

46、 non-standard code used to record extension numbers/trunk codes associated with the telephone number of a special services circuit. This data element is used in the telephone number format only, and consists of one to five characters, each of which may be alphabetic or numeric. 5.2.8 Country code Th

47、e combination of one, two, or three digits used to identify a specific country, countries in an integrated numbering plan, or a specific geographic area, as prescribed in ITU-T Rec. E.164. 5.2.9 National Significant Number (NSN) The National Significant Number (NSN) consists of the National Destinat

48、ion Code (NDC) followed by the Subscriber Number (SN). The function and format of the National Significant Number is nationally determined. The ITU-T recommends that the maximum number of digits of the National Significant Number should be equal to 12, or 15-n, where n is the number of digits of the

49、 Country code. The National Destination Code identifies a numbering area within a country (or group of countries included in one integrated numbering plan or a specific geographic area) and/or network/services. The Subscriber Number identifies a subscriber in a geographic area. The structure and functionality of the Subscriber Number is determined by the network operator.
