One basic question on the protocol used for signaling and for sending
user data in 2G,3G networks:

My understanding is this:
3G: - SS7 for signaling
- ATM cells or IP for user data

2G: - SS7 for signaling
- Which protocol is used for sending user data(both in radio part
& network), like 'voice' for example?
