[Q] How to check the mobile connection state using the terminal?

I'd like to check the state of my mobile connection.
How can I do that in terminal?

My problem is:
The phone states that it's connected to a HSDP network (showing H in the network indicator), but a connection is not available. I get timeouts.
I fear there is a discrepancy between what is shown in the indicator and the real connection state.

ifconfig states that a connection is established on ccnmi0...
