DEFENSE SWITCHED NETWORK (DSN)
As approved by OSD, the DSN is an interbase, non-secure or secure C2 telecommunications system that provides end-to-end command use and dedicated telephone service, voice-band data, and dial-up VTC for C2 and non-C2 DoD authorized users in accordance with national security directives. Non-secure dial-up voice (telephone) service is the system's principal requirement.
The primary function of the DSN is to provide non-secure dial-up voice service. The DSN provides rapid, reliable, survivable, non-secure / secure, and economical C2 telecommunications. To take advantage of economies of scale, the DSN also provides service to non-C2 users on a not-to-interfere basis.
The DSN system is used only for official business or in the interest of the government and is the first choice for all switched voice and dialup video telecommunications between DoD user locations.
