Abstract

   This document describes a Uniform Resource Name (URN) namespace
   (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.  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).

RFC 4152            URN Namespace for the CLEI Code          August 2005

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.

   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 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.
