To: NSF-Regional-Techs@merit.edu Subject: T1 NSS Dismantling Starting in the second half of February, as part of the T1 NSFNet NSS Dismantling Plan, IBM Customer Engineers will be visiting each of the NSFNET sites in order to dismantle the existing router equipment used to support the T1 backbone network, which was disconnected in December '92. To ensure a smooth process, two visits to the site will be scheduled. During the first visit, the equipment inventory will be verified. Additionally, all of the equipment will be disconnected and prepared for shipment. At that time, according to prior individual agreements, the extra RT machines will be donated to the host regional network providers who have requested them. During the second visit, the equipment will be packed and shipped. The first round of visits will be scheduled over the period of two weeks starting February 15 1993. The second visits will be scheduled during the first half of March. You will be contacted directly within the next couple of weeks in order to coordinate the exact date and time of these site visits. Several sites have asked us if they can power down the equipment during the interim. There is no problem with this, although we do request that the equipment not be moved or physically reconfigured in any way until we arrive on-site. For the purpose of serving OSI Encapsulation requirements, two RT machines equipped with one set of monitor and keyboard will remain on-site. This equipment would be mounted in one of the existing racks and will remain there until OSI support is available on the T3 Backbone (estimated for March '93). Empty equipment racks will be offered to the host regional network providers that express an interest in keeping these racks. Advanced notification of such an interest will be appreciated. Should you have any questions or special concerns, please express them as soon as possible to: Bob Farzami ANS, Netowrk Planning. <bobf@ans.net> (914) 789-5342 Thank you for your attention and cooperation.
