CC,
Yep, a report - not a broadcast. And when identified this simply is "approaching TOD", or "request descent" etc. I.e. most of the East Coast QLINK ops.
ATC can see you on the screen, you are identified.
Pingouin, the VFR traffic should be looking out the window. They are VFR. ATC should pass them as traffic to the IFR aircraft descending OCTA if workload and time permits.
