Subject: T1 NSFNet NSS Dismantling - January 1993 Dear Regional Techs: After the successful transition of all NSFNet traffic from the T1 NSFNet to the T3 ANSnet/NSFnet, the T1 network has been entirely dismantled. This event is a significant point in the evolutionary history of the NSFnet and the Internet. During the next few weeks, we will be scheduling IBM Customer Engineers to remove the T1 NSS router equipment from your sites. First, however, we would like to offer to the regional networks that have hosted the T1 NSS equipment, the opportunity to retain for your internal use some of the IBM RT workstations that comprised the Network Switching Systems of the T1 network. This equipment would be a donation from ANS - there would be no charge for the IBM RT workstations. Approximately 4-6 RT workstations are available at each T1 NSS site. Please note that due to the nature of their use as routers, the majority of the IBM RTs are NOT equipped with a monitor or keyboard. Recipients of donated RT workstations must make their own arrangements to provide monitors and keyboards for these machines. Please forward this note to the appropriate personnel within your organization, and respond to ANS with the following information (We hope to collect the replies in the first half of January 1993) : 1) Organization name 2) Organization point of contact for RT workstation disbursement 3) Requested number of workstations (not to exceed estimated number available as indicated above) Please reply to: Bob Farzami, ANS Network Planning <bobf@ans.net> (914) 798-5342 The staff at Advanced Network & Services wishes you Happy Holidays!
