Ok, that sounds like any normal 3G modem, not actually a POTS modem :)
What does "AT+GCAP" return for the device, and what driver does it use?
cdc-acm?  What are the USB IDs of it?

It's implemented on NM master using ModemManager; the NM 0.7.x
infrastructure isn't flexible enough to do it currently.  So NM 0.7.x
probably won't get this functionality, but NM 0.8 will.  You could write
a small applet that just does AT+CSQ on a secondary port periodically
and converts that from the GSM notation to suitable signal bars.  NM
0.7.x shouldn't touch secondary USB interfaces at this time.
