Airbus CVR Datalink

Caught my eye, subtly suggested in the China Eastern thread:

FCOM GEN "B" If Installed Table
DU GEN-IFIT-00016615.0001001 / 23 JUN 15
COM | CVR Datalink Function

Not installed for us, hence no info in the books. Anyone with some factual details?

The CVR records the data that the flight crew and the air traffic controller exchange, in addition to its voice recording function.

From CPDLC, that is? Makes much more sense, back from the asylum now. Thanks
