allows your Cisco DSL Router to bridge traffic in on its ATM interface

<p class=MsoNormal>> PPPoA only can run over an ATM PVC. This works fine for
an ATM setup,<br>

<p class=MsoNormal>My ISP connect to by PA-A6-OC3SMI, and it tell me
an ATM PVC to every cutomer, so I can use PPPoA<o:p></o:p></p>

<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>Now I think to start is most friendly use RFC1483, but I
don't know if I could use routed or bridge....???<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>in my country the most big telco use RFC1483 but I don't see
never our side but only customer site and I configure connction using this:<o:p></o:p></p>

<p class=MsoNormal>Now I would configure my customer with this example but I
don't configure never other side..... can you send me some example ??<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>This is is RFC1483 routed or bridge ??<o:p></o:p></p>
