[nsp] Cisco 3640 ATM and Mupltiple ISP's Question

[Kenny Stoltz]

Doesn't seem like the typical setup as they usually let you put the 
customer on whatever PVC you want, but you can grab more bits for the 
VPI through "atm maxvpi-bits" on the atm interface, which would let you 
go up to 80.

As for setting up a range I think that they want to set up different 
VPIs for each DSLAM, so you would have VPI 80, 81, 82, 83, etc. You will 
still need a VCI for each customer, unless (god help you) they are going 
to dump all the traffic from the DSLAM onto one circuit and make you 
sort it out, so your VCIs will look like 80/200. Starting at 80 is a 
really crappy idea though because it means that you don't have as many 
bits for VCI.

I am assuming this is the relationship I know of where you get an ATM 
pipe into the network and you sell DSL circuits to customers and the 
telco gets a dsl loop fee and you get the data in your atm pipe from the 
customer, is this correct? Where does "multiple isps" come in then?
