Re: [EFM] [Forecasts on 1 GE from NW]

[Date: 12/01/2001  From Seto]

Dear Richard,
Greetings to you, too.  
My point is that there are good markets for 100Mbps P2P as well 
as 1Gbps P2MP.  Remember that we don't have even 10Mbps to the 
home yet.  
Let us hear the business cases for 100Mbps P2P at the next 
meeting before making up our mind that 100Mbps P2P is waste of 

Thank you.
