ORD also has a Metering frequency. Not sure if LiveATC carries it. It is used before taxi when you are ready to taxi. The Metering controller gives you the ground frequency to monitor and puts you in the stack for the ground controller who will then call when he's ready to move you. This system means that the flights are not calling the ground controller when ready to taxi and reduces frequency congestion.
