Narrative:
During pushback;'stop; stop; stop'; followed by silence; was heard on the interphone. Airplane went from going backward to rolling forward towards the tug and terminal. Ramp person ran out of ready room under jetway; signaling us to stop and set brakes. We had no communication from pushback crew after; 'stop; stop; stop.' I applied the brakes to stop the airplane before any damage was done. We had no idea what had happened until about 10 minutes later when they were able to plug back into the interphone. They told us the airplane had come loose from the tow bar. Had the correct terminology been used; a dangerous situation could have been avoided.
