PTTs and IP service providers

I would like to hear from people who have experience with a PTT that
provides some sort of IP service as a joint venture with academia or
as a new service with no ties to academia.  Questions I have are:

- Does the PTT provide for a POP (Point of Presence) model within their
  telephone exchange buildings?
- If yes, how much does the PTT charge for the POP service? Rent? Facilities
- Does your network have the PTT providing just the fiber infrastructure for
  the IP network (levels 1 & 2 in the ISO model) or do they also provide
  all management services including routing table management, IP address
  allocation, etc.?  If they do not provide the management of the upper
  layers, who does?
- How much new manpower was required by your PTT to provide an IP service?
  Where they able to retrain X.25 network operators to be competent IP
  network operators?
- In addition to NOC (Network Operations Center) services, who provides
  NIS (Network Information Services)?  The PTT?  The consortium?  An outside
- How are shares divided between consortium owners and the PTT?

In general, does your national network work as a consortium between the PTT
and some user population, or is it solely owned by the PTT?  Anything else
you might be able to add to this topic would be greatly appreciated.
