In radio communication, a control channel is a central channel that controls other constituent radios by handling data streams. It is most often used in the context of a trunked radio system, where the control channel sends data which coordinates users in talkgroups.
In GSM networks, Control Channels can be broadly divided into 3 categories; Broadcast Control Channel (BCCH), Common Control Channel (CCCH), and Dedicated Control Channels (DCCH).

Famous quotes containing the words channel and/or control:
“There may sometimes be ungenerous attempts to keep a young man down; and they will succeed too, if he allows his mind to be diverted from its true channel to brood over the attempted injury. Cast about, and see if this feeling has not injured every person you have ever known to fall into it.”
—Abraham Lincoln (1809–1865)
“Grown-up people do very little and say a great deal.... Toddlers say very little and do a great deal.... With a toddler you cannot explain, you have to show. You cannot send, you have to take. You cannot control with words, you have to use your body.”
—Penelope Leach (20th century)
