Narrative:
We were in our descent into the miami area when we were instructed by ATC to fly heading 360 and descend to 14;000 ft. We were also told about an ATR 72 that was maintaining 13;000 ft; east bound and that it would cross from our left to right. We were on the lookout for the ATR and never had it on TCAS. We had three other aircraft on TCAS but never the ATR. After a few minutes we had a frequency change to miami center and we were cleared direct to dekal intersection and the DEKAL2 arrival. At this moment we hadn't reached 14;000 ft yet. Since we were cleared DEKAL2 arrival and we were never told to maintain 14;000 ft until further advised we proceeded to select 5;000 ft on our altitude window to continue our descent according to the published DEKAL2 arrival. Monitoring the TCAS on our navigation display we saw nothing at all whatsoever in our vicinity when suddenly looking out our windshield we saw the ATR pass by close to the right side; almost on an opposite heading. I want to reiterate that we didn't have traffic alert or resolution advisory corresponding to the proximity of the ATR. This occurred as we were descending through 13;700 ft with the ATR maintaining 13;000 ft. ATC called us asking what altitude we were leaving and advising us that the ATR was already behind us. The controller then told us that our instruction was to maintain 14;000 ft and that we could continue down to 5;000 ft. We were given a phone number to call mia center upon arrival at kfll; which we did.
