Narrative:
Due to holding being a recurrent problem all night; most inbounds to jfk needed to be manually handed off. Also; ny TRACON experienced a frequency failure. Several aircraft had to be diverted due to fuel situations. I was instructing a trainee at the time and the trainee missed a readback. Pilot read back an incorrect altitude and descended into a holding aircraft. Aircraft responded to TCAS alert.
