Expires 06/30/2005 URN Namespace for the CLEI Code [Page 1] Internet Draft 12/31/2004 Abstract This document describes a Uniform Resource Name (URN) namespace [RFC3406] that is managed by Telcordia Technologies, Inc., as the maintenance agent for ANSI T1.213 [T1.213], for the assignment of the CLEI Code, for usage within messages standardized by ANSI. The CLEI code is a globally unique, ten-character alphanumeric intelligent code assigned by Telcordia Technologies at the request of equipment suppliers. The CLEI code identifies communications equipment by specifying product type and features. There is a one-to-one relationship between a CLEI Code and supplierĘs Product ID (Manufacturer's name, part number along with it's version number).

Introduction Many circuit cards used in the global telecommunications network have a CLEI Code assigned and have a bar code or two-dimensional symbol on a label affixed to the front of that circuit card. Service providers utilize the CLEI Code to: o Track inventory, both working and spare o Logistics (movement of circuit cards, along with the serial number) o Provision equipment o Maintain asset records (accounting information) The goal of the CLEI namespace is to ensure the stability and uniqueness of the names of various (specific) items that are used within the messages exchanged between equipment used in the global telecommunications network. The assigned maintenance agent for the CLEI Code, Telcordia Technologies, is responsible for assigning certain equipment and other identifiers (e.g., location, manufacturer/supplier) for the telecommunications industry. The code assignment process identifies the structure and intelligence of the CLEI Code to identify the circuit card's form, fit, functions, and features. Equipment may exist in multiple physical locations with the exact same form, fit, functions, and features and will have the same CLEI Code if their Product ID is the same. 2. Specification Template Namespace ID: "CLEI" Registration Information: Version 1 Date: 2004-12-31 Declared registrant of the namespace: Telcordia Technologies, Inc. Customer Support Center 8 Corporate Place Expires 06/30/2005 URN Namespace for the CLEI Code [Page 3] Internet Draft 12/31/2004 Piscataway, NJ 08854 U.S.A. +1.732.699.5577 http://www.commonlanguage.com Declaration of syntactic structures: The structure of the Namespace Specific String is a flat space of 10 characters as defined in [T1.213][T1.213a]. Relevant ancillary Documentation: [T1.213] and [T1.213a]. Identifier uniqueness considerations: Identifiers are assigned by Telcordia URN registration that guarantees Uniqueness for items with different form, fit, functions, and features. This is simply achieved by keeping track of already assigned names and comparing all new proposed names to the database ones. If the name already exists a new one is created per the rules of the process. See [T1.213][T1.213a] for assignment examples. Identifiers persistence considerations: The process defined by ANSI and the CLEI maintenance agent ensure the binding between the name and its resource is permanent, and that names are not reassigned. Process of identifiers assignment: A CLEI Code is an intelligent code that consists of 10 alphanumeric characters with 4 data elements. The first data element is considered the basic code with the first 2 characters indicating the technology or equipment type with the third and fourth characters denoting the functional sub-category. The second data element represents the features and its three characters denote functional capabilities or changes. The third data element has one character and denotes a reference to manufacturer, system ID, specification or drawing. The fourth data element consists of two characters and contains complementary data. These two characters provide a means of differentiating or providing uniqueness between the eight character CLEI Codes by identifying the manufacturing vintage of the product. Names are assigned via procedures defined in [GR485]. Process for identifier resolution: Expires 06/30/2005 URN Namespace for the CLEI Code [Page 4] Internet Draft 12/31/2004 Telcordia URNs are resolved via Telcordia resolvers run under Telcordia responsibility. For further information see www.commonlanguage.com. Rules for lexical equivalence: Lexical equivalence of two CLEI URN namespace specific strings is defined as an exact, case-insensitive string match. CLEI codes are assigned in a case-insensitive fashion, so that there will not be two CLEI codes that differ only in case. See [T1.213] and [T1.213a] for further information. Conformance with URN syntax: No special consideration. Validation mechanism: None specified. Scope: Global. 3. Examples The following three examples are based on the examples provided in [T1.213a], and correspond with three different sets of features by three different manufacturers (Nortel Networks, Lear and Lucent Technologies) producing "D4CE" (a particular D4 channel bank type) equipment. The fourth example refers to a SONET power unit convertor of Alcatel. URN:CLEI:D4CE18B7AA URN:CLEI:D4CE4248AA URN:CLEI:D4CE363PAB URN:CLEI:SNPWBBC7AA 4. Namespace and Community Considerations CLEI codes have historically been used in a variety of communications equipment (see examples above and [213a]). There are circumstances where entities with CLEI codes need to be managed or exposed in a larger context, such as the general Internet. In these cases, the use of the CLEI URN namespace will provide general interoperability Expires 06/30/2005 URN Namespace for the CLEI Code [Page 5] Internet Draft 12/31/2004 benefits to the Internet at large, as well as to specific internets. 5. Security Considerations There are no additional security considerations other than those normally associated with the use and resolution of URNs in general. It is noted however that attempting to resolve a Telcordia URN through a resolver other than the one provided by Telcordia is not considered authoritative. 6. IANA Considerations The IANA has registered formal URN namespace ????, to Telcordia within the IANA registry of URN NIDs. 7.
