Default dBu transformer ratings

Are transformer ratings in dBu based on the primary or secondary side? I have some general purpose Sowter input transformers rated at 11 dBu would that be the input or output level?
Thanks,
Marty

Thanks for the reply. They are 3128 which are the same as 3678 except for no 200 ohm tap.

The 3678 has differing level capabilities depending upon which input is used which suggests that your 11dBu rating is for the 600R input tap.
