- Subject: Transition of the DDN Pilot Network Transmission Layer
-
- 1. The initial fielding of the DDN Pilot Network, or DISN-NT, transmission
- layer was supported by BBN T500 Smart Multiplexers. This network has been
- operational for about two years. It supports the router network that provides
- store and forward services to/from the civilian internet. It also supports
- eight MILNET inter-switch trunks (ISTs).
-
- 2. Due to the DISN project, and the selection of the IDNX Smart Multiplexer
- for that project, the T500s are being decommissioned. On 1-2 May 93, the T500
- network will be decommissioned and all circuits it currently supports will be
- transitioned to AFNET using IDNX equipment. This cutover could cause lengthy
- outages for the MILNET ISTs and the routers during 1-2 May. We regret any
- inconvenience caused by these outages.
-
- 3. From 3 May 93 on, all transmission layer problems should be reported to
- AFTCO Scott AFB, DSN 576-2591, commercial (618)256-2591. Any problems reported
- to the Conus MILNET Monitoring Center (CMMC) dealing with these circuits will
- be directed to AFTCO Scott AFB.
-
- 4. As stated in DDN Management Bulletin 112, DISN-NT IPR outages/problems
- should be reported to the DISN Level II monitoring center in Columbus, Ohio,
- DSN 850-8080 or commercial (614)692-8080.
-
- 5. Operational point of contact for this transition is:
- Mr Jefferson Rock, DSN 222-7580, commercial (703)692-7580,
- e-mail: inetmgr@ddn-conus.ddn.mil
- alternate POC is:
- Maj Ted Tatchio, DSN 222-2757, commercial (703)692-2757,
- e-mail: milnetmgr@ddn-conus.ddn.mil
