I would like to know what services are planned to be converged on the
next generation DSLAM boxes
from the service provider point of view. A servicve that was talked of
was the VPNs provisioned through
either ATM or IP/MPLS backbone networks. What would be the OSS support
in them? I would be interested
in the subscriber management models especially. Any known literature
available in the public domain?

I do understand that the majority of the current DSLAMs implement common
denominator function (that is to restrict their funcitonality at
switching or teminating ATM PVCs.) PPP and PPPoE,
designed to preserve dialup experience and capital investment of ISPs on
dial up infrastructure,
will be processed at the competitive or non-competitve ISP domains.
