********************************************************************** DDN MGT Bulletin 31 DCA DDN Defense Communications Systems 24 Mar 86 Published by: Network Info Center (NIC@SRI-NIC.ARPA) (800) 235-3155 DEFENSE DATA NETWORK MANAGEMENT BULLETIN The DDN MANAGEMENT BULLETIN is distributed online by the DDN Network Information Center under DCA contract as a means of communicating official policy, procedures and other information of concern to management personnel at DDN facilities. Back issues may be read through the TACNEWS server ("@n" command at the TAC) or may be obtained by FTP from the SRI-NIC host [26.0.0.73 or 10.0.0.51] using userid="anonymous" and password="guest".

We are mindful of the need to relocate communications and ADP equipment to accommodate changes and expansions at the local level. However, the increasing reliance on DDN by operational systems and the need to schedule our relocation resources dictates that we revise our policy on node relocation. We request widest dissemination of this policy. One year advance notice of a proposed DDN node relocation is required to properly plan, schedule, survey and accomplish the relocation. Notice will be provided by the local command/agency via formal message to DCA Code B652 (as action addressee) and to all intermediate Service Operations and Maintenance (O&M)/Engineering and Installation (E&I) commands and associated DDN project offices (as information addressees). The message will contain, as a minimum, the following information: a. Node name and number. b. Node Site Coordinator: (name, telephone number and electronic mail address). c. Current node location: (building, room, address). d. Proposed node location: (building, room, address). e. Date relocation must be completed. f. Reason relocation required: (include impact if not accomplished). g. Telecommunications service actions: (explain, in detail, all circuit actions required). h. Proposed schedule: (begin with proposed site survey date and show dates, required action and proposed office of primary responsibility). DCA may, on a case-by-case basis, be able to make exceptions to the one year lead time. Any DCA exception will be accomplished by formal correspondence (message or letter) and will be based on the complexity of the proposed relocation and required Telecommunications Service Request (TSR)/Telecommunications Service Order (TSO) lead times in accordance with DCA Circular 310-130-1. For example, a shorter lead time may be possible if all actions (except for the actual deinstallation/reinstallation of the DDN provided node equipment) can be accomplished by the local O&M/E&I organization and only record purpose TSR's are required. At no time is the site authorized to move equipment without DCA approval and DDN prime contractor support. Normally, a site survey will be performed for relocations, with DCA, Service (O&M/E&I) and local command participation. Additionally, the requesting organization may be required to provide a fund cite to support the cost of DCA/DDN survey and E&I support in accordance with DCA message 231613Z Apr 85, subject: DDN Node Site Surveys. All organizations supporting DDN node sites are reminded that a node relocation will require a DDN node outage with various degrees of user and DDN mission impact. For example, the removal of one node may result in single thread connectivity for other nodes. Therefore, the subsequent outage of an interswitch trunk circuit or node may isolate several other nodes and all associated host connections. Proper advanced planning will permit DCA and respective organizations to minimize the impact of the node relocation. Lack of adequate lead time may necessitate DCA directed de-installation and storage of the DDN node equipment until re-installation actions can be scheduled and accomplished. The office of primary responsibility within DCA for operational node relocation requests is the Packet Switch Operations Branch, Code B652, (703) 285-5225, (V) 356-5225, DCAB652@DDN1. The office of collateral responsibility is the Installation Management Branch, Code B642, (703) 285-5341, (V) 356-5341, DCAB642@DDN1. This policy has been disseminated as an official DCA message, date-time group 181953Z Mar 86, subject as above.
