You can query the signal quality retrieved by NM/MM directly using the 
DBus interface and the 'dbus-send' command line utility (assuming your 
modem is at index 0 here):

dbus-send --system --dest=org.freedesktop.ModemManager --print-reply 
/org/freedesktop/ModemManager/Modems/0 
org.freedesktop.ModemManager.Modem.Gsm.Network.GetSignalQuality

That won't give you neither the raw dBm value nor the rssi, though. It 
will give you a computed percentage value [0,100] representing the 
signal quality.

Cheers,
