	DSN100 defense switched network
		The DSN (Defense Switched Network), a part of the Defense Communications System, is a military network that provides preemption capabilities for calls related to national defense.
		The DSN interface, when added to a PBX (Private Branch Exchange), allows attendants and other users of the system to enter the military network by dialing an access code.
		Calls on the DSN network may be precedence or non-precedence calls.

	Defense Switched Network - Wikipedia, the free encyclopedia
		The DSN provides the worldwide non-secure voice, secure voice, data, facsimile, and video teleconferencing services for DOD Command and Control (C2) elements, their supporting activities engaged in logistics, personnel, engineering, and intelligence, as well as other Federal agencies.
		In 1982, the DSN was designated by the Office of the Secretary of Defense (OSD) and the Joint Chiefs of Staff (JCS) as the provider of long-distance communications service for the DOD.
		The DSN is designated as a primary system of communication during peacetime, periods of crisis, preattack, non-nuclear, and post-attack phases of war.

	Defense Switched Network (DSN) Information and Canadian Military Base DSN Numbers
		The DSN is the primary information transfer network for the Defense Communications System (DCS).
		In 1982, the DSN was designated by the Office of the Secretary of Defense and the Joint Chiefs of Staff (JCS) as the provider of long-distance communications service for the DOD.
		The growth of the network is such that any calls from one military organization to another will probably traverse at least one DSN switch.

	Autovon - Wikipedia, the free encyclopedia
		In the civilian networks if there are no free lines the user is unable to dial the phone, with the system typically sending the "reorder" signal (the "fast-busy") to indicate the problem.
		For instance, if the call was placed with Flash precedence and was switched to an exchange where all the lines were in use, the switch would then preempt a Routine call if there was one, and then Priority and Immediate.
		Local base switches would be connected to a few AUTOVON trunks, which the user would access by dialing 8 (or in some cases, 88) as the first digit.

		An improved joint enterprise network is a prerequisite to creating new synergies; taking advantage of all available information; and bringing available assets to bear in a rapid, precise, and flexible manner.
		To remain effective over time, the defenses must be kept current in the face of rapid evolutions of technology, attack strategies, and organizational change; this takes a significant technical and operational effort.

		The TDN is the main platform by which tactical data travels from sender to receiver, fulfilling all of the networking requirements in a given tactical environment.
		The defense switched network (DSN) is the military’s secure telephone connection that allows anyone with the proper code authentication to dial up a DSN-secure location.
		In tactical deployment situations, a version of the DSN called the defense red switched network can be used through JECCS to call back to a secure command center.

		One important caution: the proportion of, say, defense expenditures as a percentage of GDP in local currency accounts may differ substantially from the proportion when GDP accounts are expressed in PPP terms, as, for example, when an observer tries to estimate the dollar level of Russian or Japanese military expenditures.
		Note: the numbers for GDP and other economic data can not be chained together from successive volumes of the Factbook because of changes in the US dollar measuring rod, revisions of data by statistical agencies, use of new or different sources of information, and changes in national statistical methods and practices.
		Dollar figures for military expenditures should be treated with caution because of different price patterns and accounting methods among nations, as well as wide variations in the strength of their currencies.

	Networking Pipeline \| Nortel Gets Contract To Upgrade Pentagon Network
		Together with systems integrators CSC and General Dynamics, the Defense Information Systems Agency (DISA) will upgrade equipment and deploy new software to convert the existing DoD network into a private network fully controlled by the Pentagon, and mitigate current shortcomings in the current Defense Switched Network (DSN).
		"The DSN is a large, sophisticated global network that is well designed and operated, but it also has relied on a managed service from private sector telecommunications service providers for a portion of its infrastructure," Nortel president for federal solutions Chuck Saffell said in a statement.
		The upgraded network, which recently underwent rigorous certification testing by the DoD's Joint Interoperability Test Command, is also designed to provide enhanced network security at reduced costs.
