Abstract

This document describes a Uniform Resource Name (URN) namespace
[RFC3406] that
(RFC 3406) for the assignment of the Common Language Equipment
Identifier (CLEI) code, which is used in messages standardized by
ANSI. The URN namespace 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. 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
code and supplierÆs Product supplier's product ID
(Manufacturer's name, (the manufacturer's name and the part
number along with it's its version number).

RFC 4152 URN Namespace for the CLEI Code [Page 2]

Internet Draft <draft-tesink-urn-clei-00.txt> 12/31/2004 August 2005

1. Introduction

Many circuit cards used in the global telecommunications network have
a CLEI Code code assigned and have a bar code or two-dimensional symbol on
a label affixed to the front of that circuit card. front. Service providers utilize the CLEI Code
code to:

o Track inventory, both working and spare

o Logistics 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 used in of the global
telecommunications network.

The assigned maintenance agent for the CLEI Code, 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 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 features; such equipment will have the same CLEI Code code
if their
Product product ID is the same.

Declaration of syntactic structures:

The structure of the Namespace Specific String is a flat space of
10 characters characters, as defined in [T1.213][T1.213a].

Relevant ancillary Documentation: documentation:

[T1.213] and [T1.213a].

Identifier uniqueness considerations:

Identifiers are assigned by Telcordia URN registration that
guarantees Uniqueness uniqueness for items with different form, fit,
functions, and features. This is simply achieved simply by keeping track
of already assigned names and comparing all
new proposed names to the database ones. already assigned names contained in a
database. If the name already exists 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 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 type, and the third and
fourth characters denoting the functional sub-category. The
second data element represents the features 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 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 codes by
identifying the manufacturing vintage of the product. Names are
assigned via procedures defined in [GR485].

RFC 4152 URN Namespace for the CLEI Code [Page 4]

Internet Draft <draft-tesink-urn-clei-00.txt> 12/31/2004 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 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: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]). [T1.213a]). There are
circumstances
where in which 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

Internet Draft <draft-tesink-urn-clei-00.txt> 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

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 ????, to Telcordia CLEI within the IANA
registry of URN NIDs.
