ADTRAN serial numbers are used to identify manufacture and warranty dates of ADTRAN products. This document describes the different formats used on ADTRAN products for the purpose of identification.
Information regarding Warranty by product is available here: http://www.adtran.com/warranty. Support documentation for current and discontinued products is also available at https://supportforums.adtran.com.

System Serial Numbers
Note that the “CFG” format serial number is required for RMA purposes on Total Access 900 and Total Access 600 Series products.
Polycom MAC Address/Serial Number Format
Polycom IP Phones purchased via ADTRAN prior to December 2010 could be labeled with the format mentioned above as “used after 2000”.
Polycom IP Phones purchased via ADTRAN after December 2010 may contain no ADTRAN serial number. In this case, the Polycom MAC address is used as the serial number for warranty purposes.
