The driver requires Teradata Tools and Utilities (TTU) 8.2 or higher, which includes CLIv2, TGSS, and ICU client software, on all platforms. It requires TTU 12.0 to support 12.0 functionality.

Note: TTU 12.0 is not available for the Itanium II platform. You can use TTU 8.2 on an Itanium II client to connect to a Teradata 12.0 database, but functionality is limited to that of TTU 8.2.
