When receiving a channel assignment (incoming call), the
monitoring mobile immediately switches over to the assigned
data channel, and waits for a high-speed data confirmation
message. Upon receipt of this message the data paths are
unmuted and the user can complete the call.
After the initiating mobile receives a channel assignment
from the control station, it immediately switches frequency
over to the assigned data channel and sends a burst of 4800
baud dotting.
