Common Language® - V6.0

History Log

Description

Common Language® is a registered trademark of Telcordia Technologies, Incorporated and encompasses several products that are in general use by the telecommunications industry through licensing agreements. Common Language products combine numeric and mnemonics to establish naming conventions that telecommunication companies use to exchange critical information via Operations Support System (OSS) and other interface mechanisms. Naming conventions include such items as locations/sites, equipment, circuits and facilities associated with the telecommunication industry. National and international standards bodies including the American National Standards Institute (ANSI) recognize these naming and address conventions.

CenturyLink™ participates in the use of industry standard Common Language and recommends that you operate using the suggested Common Language identifiers that are found by accessing Telcordia.

How CenturyLink uses Common Language naming and address conventions are described in individual Wholesale Product and Services Catalogs (PCATs) or the CenturyLink Local Service Ordering Guide (LSOG).

CenturyLink is a participant in the Alliance for Telecommunications Industry Solutions (ATIS) standards and issue resolution committees such as the Ordering and Billing Forum (OBF) and Technical Subcommittees T1M1. These committees have control over the standards for numerous documents using Common Language. For example the Access Service Request (ASR), Local Service Request (LSR), Carrier Access Billing System (CABS), Small Exchange Carrier Access Billing (SECAB), and Multiple Exchange Carrier Access Billing (MECAB). Information regarding how you can access ATIS documents and resources may be found by accessing ATIS.

Following are examples of items that require Common Language coding when doing business with CenturyLink:

Network Identification

  • Location codes - Common Language Location Identifier (CLLI™) - each switch and premises including a Central Office (CO) in the CenturyLink network or in your network should be assigned a CLLI by Telcordia. CLLIs are also assigned to each of your various collocation arrangements in a CenturyLink premises in which you collocate. When designing your network, you must know the CenturyLink CLLI for the CenturyLink CO in which you intend to have an Interconnection presence. You also need CLLIs for your collocation arrangement when used to cross connect your collocation equipment to CenturyLink for the purpose of Interconnection, access to Unbundled Network Elements (UNEs), ancillary services or finished services. The CLLI code will be entered on the ASR/LSR as described in the LSOG. For information on how to obtain CLLI codes, access the Telcordia Common Language Products Code Center or Getting Started as a Facility-Based CLEC or Getting Started as a Reseller.

    • Message trunk circuit codes - used on interconnection trunks
    • Special service circuit codes - used for unbundled loop and unbundled transport products
  • Network Channel (NC) and Network Channel Interface (NCI) codes - used on all Interconnection trunks and most unbundled products as defined in the individual PCAT or associated technical publication. A definition of each NC/NCI™ code is found in the specific technical publication. The NC/NCI code will be entered on the LSR as defined in the LSOG. Refer to individual Wholesale Products and Services Catalog for additional information.
  • General codes - such as Access Customer Name Abbreviation (ACNA) and Carrier Identification Code (CIC) are used to identify service providers and to support network operations. These codes will be entered on the LSR as defined in the LSOG.
