If they are separate how is one ranked higher?

They are separate until they reach the Exchange. Given a phone number (aaa) xxx-yyyy. 'a' is the area code, a collection of Exchanges, 'xxx' designates a specific the Exchange (referred to as 'switch' above) and 'yyyy' are the 10K individual telephone numbers associated with that Exchange. There may be multiple Exchanges physically located within a single Central Office building.
At the Exchange switch any call not already in digital form (analog) is converted to digital format. All calls are inserted into gaps in the IP data traffic as so much 'filler'. Voice phone calls have a relatively low data rate compared to say, full motion video conferencing, and can tolerate a very high rate of packet loss. The human ear is very good at audio error correction.
Land lines do NOT rank higher than cell phones. A call is a call. A given cell phone tower can only process so many calls at one time. This is primarily a economic consideration. Cell providers don't provide excess capacity unless they absolutely have to.
I have a patent in Electronic Warfare (owned by the Government but my name is on it) which is relevant to the 'jamming' issue in the main body of the thread. Jamming in the civilian world is merely a point source of interference.
If anyone has a question I will try to answer it.
