The URN namespace is managed by Telcordia Technologies, Inc., + as the maintenance agent for ANSI T1.213. 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 supplier's product ID (the manufacturer's name and the part + number along with its version number). + +Table of Contents + + 1.

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. Service providers utilize the CLEI + code to: + + o Track inventory, both working and spare + + o Handle 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 of 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; such equipment will have the same CLEI code + if their product ID is the same. + +2.

This is achieved simply by comparing all + new proposed names to the already assigned names contained in a + database. 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 + that 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, and 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 a + 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]. + + + + + + +Tesink & Fox Informational [Page 3] + +RFC 4152 URN Namespace for the CLEI Code August 2005 + + + Process for identifier resolution: + + 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 [T1.213a]). There are + circumstances in which entities with CLEI codes need to be managed or + exposed in a larger context, such as the general Internet. In these + + + + + +Tesink & Fox Informational [Page 4] + +RFC 4152 URN Namespace for the CLEI Code August 2005 + + + cases, the use of the CLEI URN namespace will provide general + interoperability 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. + + However, note 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 the formal URN namespace CLEI within the IANA + registry of URN NIDs. + +7.
