[AusNOG] Discussion point: Why aren't the NBNCo tails symmetric in speed?

[Joseph Goldman]

I was personally reading it as you need to purchase 2x lots of CVC, one 
for each Traffic Class, so your TC-4 circuits will deliver over your 
TC-4 CVC (only), and your TC-2 circuits will deliver over your TC-2 CVC, 
so if you wanted to supply both TC-4 and TC-2 services, you'd be 
spending $2000/100mbps x 2 on top of the circuit costs, rather than 
$2000/100mbps x 1 and both TC's share it.

Could well be wrong though.
