Some CDMA channels exist for the sole purpose of carrying messages; they never carry user’s voice traffic
Sync Channel (a forward channel)
Paging Channel (a forward channel)
Access Channel (a reverse channel)
On these channels, there are only messages, continuously all of the time
Some CDMA channels exist just to carry user traffic
Forward Traffic Channel
Reverse Traffic Channel
