And by "connected to the public network" they mean "in any way through any
device". So even if you isolate your network from the public one with a
router or modem etc, you're still deemed to be "connected". Not sure if
you're still deemed to be connected if the external/public link is wireless
though (they are more concerned about electrical isolation than spurious
data).
At tleast this was how the regs were written back in '95 when I was AUSTel
Certified. Things may have changed - usual disclaimers apply.
