The length and type of cable will also have an effect on the properties of the signal. You can get an idea of what is possible by looking at the transmitter characteristics in terms of "what is a 1" and "what is a 0". then look at the receiver characteristics to see what it would take for a "0" to change to a "1" and vice versa.Even though there are 128 possibilities for addresses, the actual limitation is typically due to the loading each device adds to the line. This is due to the capacitance each gate adds. So, the answer is, it depends. It depends on the devices' electrical properties.
