Configuring PPP over ATM SVCs

Trying to configure PPP over ATM using SVC through this doc: http://www.cisco.com/en/US/products/sw/iosswrel/ps1835/products_configuration_guide_chapter09186a0080080fc8.html#1072921

Any feedback appreciated.

My lack of experiency using this feature make me think I could test it pinging 1.1.4.9, but Cisco example does not configure remote ATM SVC address.
How is the remote SVC address acquired on real use of this feature?
Is it possible to simulate it on lab?

Here the configuration I used:

r6#sh run
interface ATM1/0.369 multipoint
 atm nsap-address 47.00000000000000000000000A.466666666666.00
 !
 svc PPPoATM
  encapsulation aal5auto
  protocol ppp Virtual-Template2
 !
interface Virtual-Template2
 ip address 1.1.4.6 255.255.255.0

r9#sh run
interface ATM1/0.369 multipoint
 atm esi-address 499999999999.00
 !
 svc PPPoATM
  encapsulation aal5auto
  protocol ppp Virtual-Template2
 !
interface Virtual-Template2
 ip address 1.1.4.9 255.255.255.0

I tried this (may look crazy; as I did not find any example I tried to force a remote ATM SVC address):

r6#sh run int atm 1/0.369
Building configuration...

Current configuration : 270 bytes
!
interface ATM1/0.369 multipoint
 atm nsap-address 47.00000000000000000000000A.466666666666.00
 !
 svc nsap 47.00000000000000000000000A.499999999999.00
  protocol ip 1.1.4.9 broadcast
 !
 !
 svc PPPoATM
  encapsulation aal5auto
  protocol ppp Virtual-Template2
 !
end

r9#sh run int atm 1/0.369
Building configuration...

Current configuration : 241 bytes
!
interface ATM1/0.369 multipoint
 atm esi-address 499999999999.00
 !
 svc nsap 47.00000000000000000000000A.466666666666.00
  protocol ip 1.1.4.6 broadcast
 !
 !
 svc PPPoATM
  encapsulation aal5auto
  protocol ppp Virtual-Template2
 !
end

I tested PPP over ATM with PVC on the same devices, it works fine. The problem is just to test PPP over ATM using SVC.

Any feedback appreciated.
