We currently have two customers both with Cisco 2651XM's configured with a standard ATM WIC card and ISDN BRI card. Both are connected to BT Wholesale provided IPStream MAX Premium DSL services. Both sites are running "c2600-advsecurityk9-mz.123-8.T3" as their IOS. The routers are both configured with PPP and Virtual Access 2 is currently up/down. The strange part comes when I do "sh dsl int ATM0/0". On the downstream the router reports the DSL using interleaving and on the upstream using fastpath. As far as I'm aware this is impossible but BTWS are saying the circuits are configured correctly and they can see no problems. Both circuits have also been rebuilt. Has anyone come across this issue before or know how to resolve it?
I have this problem too.
