HWIC-4SHDSL for 32 PVC

Hello
Please give me the required guideline for configuring up to 32 permanent virtual circuits (PVC) per HWIC-4SHDSL if it is feasible. I am using a CISCO3845 router with two of HWIC-4SHDSL and the IOS of S384AESK9-12415T.

It should just be a matter of going through with ATM subinterfaces.

int atm 1/1.32
pvc 0/32
encaps ...
...
int atm 1/1.33
pvc 0/33
encaps ...
...
int atm 1/1.34
pvc 0/34
encaps ...
...

etc. etc.
But I guess I fail to see why you need so many? Almost all implementations would use a single PVC, very special setups may require 2-4?
What would you need 32 for? What are you trying to do?

Dear
Thank you for reply.
With this IOS version, HWIC-4SHDSL can create maximum of two ATM interfaces (using dsl-group command, each dsl group will create one ATM Interface) and I can create maximum of 8 ATM sub-interface (PVC configured as mentioned above) per each ATM interface. However, I know that Cisco in the datasheet of "Cisco Symmetric High-Bitrate DSL High Speed WAN Interface Cards for Cisco Integrated Services Routers" which includes both 2-pair (HWIC-2SHDSL) and 4-pair (HWIC-4SHDSL) modules, mentioned that they can only "Sustains up to 8 permanent virtual circuits (PVCs) per HWIC". In my scenario, I want to connect 64 branch offices to my HQ office. Each branch office connects with a 64Kbps link to WAN and I want to use this 3845 router in the HQ and connect a group of 32 branch offices to one of HWIC modules that installed on the 3845. Do you have any better Idea?
