Yes you can have multiple VC's on GPON but the lower equipment cost and lack of ATM cell tax coupled with now higher line rates of 10G EPON surely make this a better option. Anyone want to change my thinking?<div><br><div><div>On 16/09/2009, at 3:43 PM, Narelle wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div> </div>

<div><font face="Arial" size="2"><span class="008162002-16092009">It looks like a layer 2 GPON network with ethernet backhaul over classical transmission gear, presenting to service providers from centralised locations. Each premises will have an ONT with multiple ports so there can be physical separation of services. He says this is merely a "stake in the ground" and will consult with ISPs.</span></font></div>
