Lets see..

Downstream: 7Mbit/Sec
Upstream : 320k bps
Interleave : off (RTT 15ms)

That looks a lot like what TelstraClear have asked the Commerce Commision
for.
Maybe Telecom are trialing a new service to meet those requirements.

I don't think TelstraClear specified what the packet loss should be, so...

OK, that's 2mbit/sec average throughput, OK for the Internet but VOIP could
be a real challenge ;)
