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

[Tony]

"recently" as in 21 days in the future from now ! That doc is dated  
30/04/2014 ;)

As others have already stated, the asymmetrical nature of the tail speeds  
is due to the use of GPON.

I would assume the 40M/40M TC2 product is just a 100/40 tail with the  
downstream limited to 40M to make it symmetrical ?

It's interesting to see TC2 available now. Is TC3 released yet ?

If you want a symmetrical tail above 40M, then you're still going to be  
better going to the traditional carriers that you would use now. IF at  
some point in the future NBN fibre is actually rolled out and IF at some  
point the 1000/400 product becomes widely available and IF TC3 is  
available for the full 1000/400 of the service then it would be something  
that MIGHT compete with going and buying fibre from whoever you would now.  
About two years ago Telstra & Optus (and quite probably AAPT, PIPE, others  
as well) dropped the pricing on a 100M fibre tail service in anticipation  
of competition from NBN. This is guaranteed 100M symmetrical bandwidth  
between the two points, no asymmetrical and I don't have to buy some  
"class" of traffic to make sure my traffic makes it from A to B.

I'm not sure of which of all of those bits in the NBN pricelist I need.  
Can someone who knows tell me what it would cost for that 40M symmetrical  
TC2 service from NBN ?


regards,
Tony.
