<DIV><SPAN class=565213022-10122004><FONT face=Arial color=#0000ff size=2>You
are correct, the PA-A3 does have a limitation of 4000 *active* VCs but you can
configure more than this using the feature called "create on-demand" or ATM PVC
autoprovisioning. There are a number of ways of applying this (through a
vc-class, through a vc-range, applied directly to the interface, or a
combination of these).</FONT></SPAN></DIV>

<DIV><SPAN class=565213022-10122004><FONT face=Arial color=#0000ff size=2>For
the Cisco 10000, you are able to use create on-demand within a pvc-range or
inside a vc-class that is assigned to the pvc-range which basically enables the
creation of VCs when the router receives ATM cells from the other end of the
VC. This conserves resources and CPU and enables VC oversubscription as
you are looking for. I would suggest looking at the following for more
details:</FONT></SPAN></DIV>

style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">Andy, how does the
ATM oversubscription work? In the proof-of-concept, we have used a 7206 VXR w
NPE400, we configure an ATM subinterface with an atm pvc-range. On the current
PA-A3’s, the maximum VC’s is 4000, to be honest I’ve not tried configuring any
more than this. So is the VC limit on the PA/ Line card for ‘active’ or
‘configured’ VCs?<o:p></o:p></SPAN></FONT></P>
<P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN
style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">If oversubscription
means that you can configure more PVC’s than the defined maximum for the PA/
Line card then that is useful, however if it just means you can oversubscribe
the SCR on VBR-nrt PVCs then that’s not so useful in my
scenario.<o:p></o:p></SPAN></FONT></P>

excellent alternative to other vendor's BRAS options. The Cisco 10000

Service Providers on this alias attest to their experience with the Cisco
10000 but I wanted to reaffirm that the Cisco 10000 does perform as a BRAS and
does it very well (I'm a bit biased).</SPAN></FONT><o:p></o:p></P></DIV>
