[c-nsp] atm ds3 to a cisco 7200 for adsl aggregation

[Chad Whitten]

it is a pa-a3-t3 card

i do have the subinterfaces configured for the subscriber and am doing
rbe.  we were doing this off atm t1's and everything worked fine.  we put
in a ds3 to migrate off the t1's and cant seem to get it working.
