1、 AMERICAN NATIONAL STANDARD FOR TELECOMMUNICATIONS ATIS-0300007.2007 IDENTIFICATION OF PHYSICAL NETWORK RESOURCES ATIS is the leading technical planning and standards development organization committed to the rapid development of global, market-driven standards for the information, entertainment and

2、 communications industry. More than 250 companies actively formulate standards in ATIS 20 Committees, covering issues including: IPTV, Service Oriented Networks, Home Networking, Energy Efficiency, IP-Based and Wireless Technologies, Quality of Service, Billing and Operational Support. In addition,

3、numerous Incubators, Focus and Exploratory Groups address emerging industry priorities including “Green”, IP Downloadable Security, Next Generation Carrier Interconnect, IPv6 and Convergence. ATIS is the North American Organizational Partner for the 3rd Generation Partnership Project (3GPP), a membe

4、r and major U.S. contributor to the International Telecommunication Union (ITU) Radio and Telecommunications Sectors, and a member of the Inter-American Telecommunication Commission (CITEL). For more information, please visit . AMERICAN NATIONAL STANDARD Approval of an American National Standard req

5、uires 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, substantial agreement has been reached by directly and materially aff

6、ected 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 use of American National Standards is completely voluntary;

7、their existence does not in any respect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will

8、 in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute. Requests for interpretations should be addressed

9、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 withdrawn at any time. The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or

10、withdraw this standard. Purchasers of American National Standards may receive current information on all standards by calling or writing the American National Standards Institute.

A carrier facility generally consists of multiplex equipment at two terminal locations and an interconnection path consisting of: (1) a higher level facility system; (2

30、) a facility assembly; or (3) combinations of carrier facility systems and facility assemblies,” where facility is defined as “a physical or derived telecommunications path between two locations, which can be intraoffice as well as interoffice. A facility is bounded by its transmission signal input

31、to its equivalent transmission signal output, or its point of termination at another operating or interconnecting telephone company. A facility has the same capacity at each end and normally carries assignable channels, pairs, or time slots.” Facility assembly is defined as “a group of interconnecte

37、onnel 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 either eight or eleven characters, as allowed by the requirements of ATIS-0300253.2005.” Lo
