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 management? - 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 contractor? - 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. Thanks, Hank Nussbacher Israel
