DDN SCHEDULED SERVICE INTERRUPTIONS
DDN Management Bulletin 102, dated 6 October 1992, subject "MILNET PSN

This DDN Managnement Bulletin provides updated information regarding
scheduled service interruption procedures, effective upon receipt.
This DDN Management Bulletin also provides NEW guidance on how to submit
requests for DDN MILNET PSN Scheduled Service Interruption requests
for approval.
In the past few months, DISA/DODM has received numerous requests for
scheduled downtime at DDN MILNET PSN facilities without proper coordination
and no end user validation. Further, DISA/DODM has received requests from
Node Site Coordinators through the CONUS MILNET Monitoring Center (CMMC).
The CMMC is not authorized to approve Scheduled Service Interruption
requests without prior approval from DONC/DODM. Requests for Scheduled
Service Interruptions should not be submitted to the CMMC--except as
INFORMATION ONLY.
Procedures and guidelines for DDN Scheduled Service Interruptions are
provided in DISA Circular 310-70-1, DCS Systems Control, Operational

management of the DCS (Defense Communications System), which includes
DDN MILNET PSNs and its Interswitch Trunks (ISTs).
All future requests for DDN Backbone Scheduled Service Interruptions
should be submitted as directed by the DISA Circular referenced above.

please check with your local Techincal Control Facility (TCF), Patch and
