## Solution

From [RFC4152](http://www.ietf.org/rfc/rfc4152.txt):

<br />

<br />

<br />

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.  

<br />

<br />

A CLEI code is an intelligent code that consists of 10 alphanumeric characters with 4 data elements.

<br />

* The first data element is considered the basic code with the first 2 characters indicating the technology or equipment type.   

<br />

* 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.   

<br />

* 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.

<br />

<br />

<br />

**How is RoHS reflected within the CLEI Code Set?**   

COMMON LANGUAGE Equipment Codes (CLEI Codes) will allow for recording and tracking RoHS compliancy and the level of compliance within the Hazardous Material Indictor (HMI) field. The data will be displayed to the end user as found appropriate for each record, manufacturer's product that supports RoHS as either RoHS-5 or RoHS-6.

All Nokia Appliances are RoHS compliant
