The Common Language Equipment Identifier, CLEI, code is a unique 10-character identifier, that is fixed by the manufacturer. It consists of ten alphanumeric characters. The first seven characters present a concise summary of an equipment entity's circuit or transport capabilities, e.g., functional, electrical, bandwidth, etc. CLEI codes for plug-in or portable equipment with the same first seven characters (CLEI-7) are considered bidirectionally interchangeable and group under a G level record. Most licensees plug-in inventories and records are controlled at the group level. The eighth character denotes the reference source used for coding the item, and the last two characters denote manufacturing vintage or version, and other complemental information. A ten-character CLEI code that is developed for a specific piece of equipment is unique within the CLEI code universe and is used in A level records; the code is not assigned to any other equipment piece. Equipment is coded to a first or major application. When the same equipment is usable in another application or system, it is not recorded nor are additional codes developed for that purpose.
