Procedure; Chart Or Publication
I was flying into SLC at FL220 on the Brigham City Three Arrival. I was cleared direct to CARTR and instructed to descend at pilots discretion to cross CARTR at 14;000 [feet]. A few minutes later I notified Salt Lake Center that I was starting down.  As I was descending  below 15;000 for 14;000 center tells me to climb and maintain 16;000 and asks me what altitude I was cleared to. I said that I was cleared to cross CARTR at 14;000. They then asked what I wanted and I said 14;000 then they re-cleared me to 14;000. ATC uses CARTR as crossing restriction at various altitudes all the time. I think this error could be reduced if the Brigham City Three arrival had a crossing restriction for turbo props at CARTR for a specific altitude; for example 14;000.
A Pilot began a descent to cross CARTR at 14;000 feet on the SLC Brigham City Three Arrival but passing 15;000 feet was told return to 16;000 feet. The confused pilot commented ATC clears aircraft to cross CARTR at various altitudes but 14;000 feet for turboprops works best.
