Class C
Two-way radio communication must be established before you enter.
Established means they answered you by callsign. “Aircraft calling, stand by” is not established and you stay out; “Cessna 12345, stand by” is, and you may enter. Mode C is required within the lateral limits and above them to 10,000 ft MSL. VFR traffic gets sequencing and traffic advisories, not separation.
