Yes, of course.
35 channels = 35 simultaneous calls
35 parking spaces = 35 parked cars
problem is that if mobile n°36 tries to get a channel, it will be rejected.

and who knows what happens to rejected MS. They start drinking, get high, and ends up shooting random iPhones in the streets. Not pretty. Not pretty at all.
