19、The code structures and their uses are as follows: 3.1 Exchange Carrier Code (EC Code) A unique four-character alphabetic code (AAAA) that identifies the legal company name shall be assigned, as appropriate, to represent each exchange carrier. An exception is where 24 two-character codes representin
20、g companies of the former Bell System have already been assigned. 1See 47 U.S.C. 153, Definitions. ATIS-0300251.2007 3 EC Codes are assigned to exchange carriers to facilitate the exchange of information between communications industry trading partners. One code per legal company name shall be assig
21、ned in the event of a new code creation. Legal documentation is required to substantiate the existence and identity of the legal company name. 3.2 Interexchange Access Customer Code (IAC Code) IAC Codes are assigned to identify customers receiving services offered by exchange carriers. A unique thre
22、e-character alphabetic code (AAA) that identifies the legal company name shall be assigned, as appropriate, to represent each customer. Legal documentation is required to substantiate the existence and identity of the legal company name. Examples of customer types are: Inter-LATA transport carriers
23、requesting Exchange Access Service; Inter-LATA transport service companies providing transport for Exchange Access Service customers; Agencies requesting services for Exchange Access customers; and Resellers or end users receiving an Exchange Access Service. One code per legal company name shall be
24、assigned in the event of a new code creation. Legal documentation is required to substantiate the existence and identity of the legal company name. 3.3 Company Code (CC) A unique four-character alphanumeric code (NXXX) shall be assigned - as appropriate - to all service providers. Area, category, an
25、d country are required attributes of the lowest level of Company Code - i.e., required for a valid area-specific Company Code. One code per legal entity is assigned for each unique combination of required attributes. Legal entities with more than one combination of required attributes shall require
26、more than one code. In addition, a unique four-character code (NXXX) shall be assigned to an overall company when one legal entity provides one type of ICT service in more than one area within a country. Category and country are required attributes of an Overall Company Code - i.e., required for a v
27、alid Overall Company Code. The service providers legal name and contact information shall be associated with the Company Code. Company Codes are assigned to service providers for unique identification. The code set is used in mechanized systems throughout the ICT industry to facilitate the exchange
28、of information. Applications of the Company Code include, but are not limited to: NECA Tariff F.C.C. No. 4; NRRIC Routing and Rating Practices; ATIS-0300251.2007 4 Industry recognized guidelines including Access/Local Service Requests (ASR/LSR), Multiple Exchange Carrier Access Billing (MECAB), Smal
29、l Exchange Carrier Access Billing (SECAB), Carrier Access Billing Systems (CABS), Exchange Message Interface (EMI), and Wireless Intercarrier Communications Interface Specifications (WICIS); Interexchange Carrier systems to audit Exchange Access bills; and F.C.C. Form 502 (North American Numbering P
30、lan Numbering Resource Utilization/Forecast Report). Company Code data is the basis for Operating Company Number (OCN) and Service Provider Identifier (SPID) data, which are also used in the industry to identify service providers. 4 CODE ASSIGNMENT PROCESS The legal entity to which a code is to be a
31、ssigned shall notify all maintenance agents and provide sufficient legal documentation in a timely manner, per maintenance agent procedures, in order for the maintenance agents to perform their duties. Others - aside from the legal entity being represented - may request code assignments for the lega
32、l entity, provided that legal documentation is submitted to the maintenance agents. Additional documentation may be requested by the maintenance agent to authorize the request. Maintenance agents are identified in Annex A. The set of code values shall be restricted to those assigned by the maintenan
33、ce agents. Locally assigned codes shall not be utilized. The assignment of all EC, IAC, and Company Code values shall exclusively reside with the maintenance agents identified in Annex A. Any other codes are invalid and shall not be utilized. All attributes to any code value shall be restricted to t
34、hose maintained by the maintenance agents. For instance Company Code values and the assigned legal entity name, category, and operating state/province are assigned by the Company Code maintenance agent and can not be overridden in whole or part by any user of the data. In the case of the IAC code se
35、t, the attribute of a code is the company name. 4.1 Initial Request In order for a code to be assigned to a legal entity, that legal entity shall request a code or codes of the relevant maintenance agent, as identified in Annex A. 4.2 Expansion of coverage area or offered service categories If a ser
36、vice provider expands operations such that additional Company Code(s) are required, new code(s) shall be requested to represent the expanded portion of the business. The following attributes: area, category, and country, once assigned to a Company Code, shall not be changed. A new, unique combinatio
37、n of these attributes shall result in a new code(s) being assigned. ATIS-0300251.2007 5 4.3 Name Change In the event of a name change of an existing legal entity with assigned code(s), that entity shall notify each maintenance agent and provide sufficient documentation in a timely manner for the mai
38、ntenance agent to make the necessary change(s). The new legal entity name shall be associated with the existing EC Code, IAC Code, and/or Company Code, and the previous legal entity names shall be captured as a historical cross reference. 4.4 Mergers In the event of a merger of two or more existing
39、legal entities, the surviving legal entity shall notify each affected maintenance agent and provide sufficient documentation in a timely manner for the maintenance agent to make the necessary administrative change(s). a) The EC, IAC, and/or Company Codes originally assigned to the surviving legal en
40、tity shall be retained. b) The EC, IAC, and/or Company Codes originally assigned to the non-surviving legal entity(ies) may, at the discretion of the surviving legal entity, be retained in a manner that is consistent with the code structure requirements identified in clause 3 of this standard. Such
41、codes shall be identified distinctly from the EC, IAC, and/or Company Code originally assigned to the surviving legal entity. 4.5 Bankruptcy Process a) In the event of bankruptcy-related proceedings that have an impact on the codes, the company(s) involved with the bankruptcy shall notify the affect
42、ed maintenance agents and provide sufficient documentation in a timely manner for the maintenance agent to make any necessary change(s). b) Due to the complexities of bankruptcy-related proceedings, the surviving legal entities or involved companies shall coordinate with their trading partners as we
43、ll as the maintenance agents for the best solution. Any solution should take into account ancillary data for which the EC, IAC or Company Codes are attributes as well as the impacts to all affected business (e.g., billing, trouble reporting, regulatory reporting, etc.). 4.6 Reassignment Codes no lon
44、ger utilized shall not be reassigned unless required to prevent code exhaustion. 5 RESPONSIBILITIES OF A CODE REQUESTOR A code requestor shall obtain, modify, and use codes in a manner that is consistent with this standard and with maintenance agent procedures. A code requestor shall supply accurate
45、 and complete supporting information. The Maintenance Agent is not responsible, nor accountable, for information provided by a requestor seeking code assignments. ATIS-0300251.2007 6 It should be noted that data is shared between companies, and a change with one company may drastically impact other
46、companies operations. The surviving legal entity shall be responsible for cross-company coordination due to name changes, mergers, bankruptcy-related proceedings, etc., to ensure that the surviving legal entity and associated records do not create problems for the ICT Industry. Timely notification w
47、ill help avoid operational difficulties for the company whose name has been changed. For example, interconnecting companies may erroneously create additional codes which will create rework, or may refuse to pay invoices where the invoicing company name and the legal name associated with the code(s)
48、are different. A code requestor who cannot do business with code sets maintained in accordance with this ANS should contact ATIS for information on how to resolve the issue(s) within the scope of standards development and management. 6 DUTIES OF THE MAINTENANCE AGENT(S) A maintenance agent shall be
49、assigned to provide for the assignment and administration of each of the codes defined in this standard. A maintenance agent shall administer one or more of the codes defined in this standard. Multiple maintenance agents shall share code information as appropriate. Maintenance agent responsibilities are as follows: a) Provide an industry procedure for obtaining new codes and modifying attributes of existing codes. b) Provide a method for the distinct identification of EC, IAC, and/or Company Codes originally assigned to non-surviving l
