AMERICAN NATIONAL 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. Conse
6、nsus is established when, in the judgment of the ANSI Board of Standards Review, substantial 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 ob
7、jections be considered, and that a concerted effort be made towards their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing, or u
8、sing products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an inter
9、pretation of an American National Standard in the name of the American National Standards Institute. Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on the title page of this standard. CAUTION NOTICE: This American National Standard may be revised or

In the format layouts in clause 6, character positions that require alphabetic, numeric, or either alphabetic or numeric characters are represented by “A”, “
28、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 letters. 5 DATA ELEMENTS Clause 6 of this standard
29、describes location code formats that contain data elements that are defined and described in the following subclauses. 5.1 Geographical Code The designation for a single geographical locality within a state, province, territory, country, or distinct region of the world (e.g., municipality). This dat
30、a element shall consist of four alphabetic characters. New codes assigned shall contain exactly four characters and shall not contain spaces. For previously assigned codes of less than four characters, the unused character positions after the code shall be filled with spaces to make up four characte
31、r positions. 5.2 Geopolitical Code The designation of a state or territory of the United States, a province or territory of Canada, another country having a national federal government, or a unique designation (e.g., the oceans). This data element shall consist of two alphabetic characters. 5.3 Netw
32、ork Site Code The designation of a site of an existing or proposed structure within a geographical location where there is a need to identify one or more ICT equipment entities, facility terminations, nodal locations, or ATIS-0325300.2011 4administrative operations. This data element shall consist o
33、f either two alphabetic or two numeric cha-racters. 5.4 Network Entity Code A functional category of equipment or work center that is contained in a structure. Equipment catego-ries, including central office switching and ancillary equipment or non-switching or access termina-tions, are associated w
34、ith a building or network site for purposes of maintaining equipment inventories and for identifying facility and circuit terminations and nodal locations. This data element shall consist of three alphabetic or numeric characters, based on a predefined format category that is suitable for the applic
35、ation. 5.5 Network Support Site Code Network support site codes are used to identify equipment or facilities at a specific location. This code uniquely identifies communications equipment or a junction point for the purpose of inventory or facil-ity management. NOTE - The site corresponding to this
36、code may be collocated with the site corresponding to a Network Site Code or a Customer Site Code. This data element shall consist of five characters having a predefined alphabetic character in the first position followed by one numeric and three alphabetic or numeric characters in that sequence. 5.
37、6 Customer Site Code The designation of a customer that utilizes ICT equipment at a specific location where there is a re-quirement to uniquely identify that customers presence for the purpose of inventory and facility man-agement. NOTE - The site corresponding to this code may be collocated with th
38、e site corresponding to a Network Site Code or a Network Support Site Code. This data element shall consist of five characters having one numeric character in the first position fol-lowed by one alphabetic and three alphabetic or numeric characters in that sequence. 6 DATA COMPOSITES The data elemen
39、ts are combined in one of the prescribed sequences shown below to uniquely identify specific sites. The type of data composite can be determined from its length and the characters in posi-tions 7 and 8 (alphabetic and/or numeric). The possible data composite formats are as described in the following

48、for geographical locations (e.g., cities, towns, areas) within states, territories, prov-inces, and countries shall be assigned by the maintenance agent to be unique within that state, territory, province, or country. It is desirable that mnemonic codes are used, that is, that codes be derived from
49、the common name of a geographical location - i.e., a common abbreviation or a series of significant letters of the name. When a new code is to be assigned for a geographical location for which the com-mon name of the geographical location contains fewer than four alphabetic characters, the last charac-ter of the common name shall be repeated as many times as necessary to make a four-character code. For example, RYE is coded as RYEE. It is the intention of this stand
