What does non-xt stand for?

[bertilback]

Looking to maybe buy a cRIO-9056, 1.33 GHz Dual-Core, Artix-7 75T FPGA, 8-Slot, RT, Non-XT but can not figure out what the Non-XT stands for.

Help?

I think XT here means "eXtended Temperature".  The cRIO-9056 has a temperature range of -20C to +55C.  Same for the cRIO-9057 (same range of controllers, but better specs).  But then the cRIO-9058 has a temperature range of -40C to +70C.
