Defense Switched Network (DSN) Information
and Canadian Military Base DSN Numbers

10/22/96



A Brief Description of the Defense Switched Network
  1. The DSN is the primary information transfer network for the Defense Communications System (DCS). It provides the worldwide 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.
  2. 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. It is designated as a primary system of communication during peacetime, periods of crisis, preattack, nonnuclear, and post- attack phases of war. The network assures nonblocking service for users with FLASH and FLASH OVERRIDE precedence capabilities. Key users include the National Command Authority, Commanders in Chief (CINCs) of the Unified Commands, and strategic and tactical subordinate commanders.
  3. The DSN consists of four subsystems: Switching, Transmission, Timing and Synchronization, and Network Administration and Management. The DSN Switching Subsystem consists of multifunction, stand-alone tandem, end office, and remote switching units. Using transmission, timing, and control elements of the DCS, they interconnect all military locations worldwide and provide end-to-end long-distance common user and dedicated voice, secure voice, data, and video services worldwide. The DSN includes the former Automatic Voice Network (AUTOVON) System, the European Telephone System (ETS), the Japanese and Korean Telephone Upgrades, (JTU and KTU), the Oahu Telephone System (OTS), the Defense Commercial Telecommunications Network (DCTN)/DCTN Transition Network (DTN), the Defense RED Switch Network (DRSN), the Video Teleconferencing Network (VTN), and others.
  4. The growth of the network is such that any calls from one military organization to another will probably traverse at least one DSN switch. Overseas, the DSN has four times as many tandem nodes as the old AUTOVON System. The full overseas DSN, including end offices, is 15 to 20 times larger than the old AUTOVON. The result is greater accessibility to the network for users and a more robust and survivable system to support mission requirements.
  5. In addition to nonsecure voice, data, and video services, the DSN will provide transmission, switching, and support services for Secure Telephone Units Third Generation (STU- IIIs), the DRSN, the Unclassified, but Sensitive Internet Protocol (IP) Routing Network (NIPRNET), and the Secret IP Routing Network (SIPRNET).

National Communications System Voice Precedence System
1.   The National Communications System (NCS) Voice Precedence
System, established by NCS Memorandum 1-70, dated 14 February
1970, is directed for use by all authorized users of the DOD
voice communications facilities.  Since the effectiveness of the
system depends on the cooperation of the people authorized to
employ it, users must: (1) be familiar with the purposes of each
precedence category and the type of call that is assigned the
precedence, and (2) exercise care not to request or use a
precedence higher than required.

2.   The NCS Voice Precedence System does not make provisions for
conducting test and exercise calls.  Those activities or
individuals authorized or required to conduct such test or
exercise calls will employ a precedence consistent with the
nature of the test or exercise.  When the originator of the test
or exercise call has contacted the called party, the call will
immediately be identified as a FLASH, IMMEDIATE, or PRIORITY
precedence test or exercise.

3.   The following examples should aid users in determining what
precedence to use when placing a call.  These examples are in
accordance with the NCS Voice Precedence System, but are not to
be used exclusively for determination of the precedence of a
call.  This should be at the discretion of the originator of the call.

     a.   FLASH OVERRIDE

FLASH OVERRIDE is considered a capability, not a level of
precedence.  Exercising this capability preempts calls of all
other levels or precedence.  The FLASH OVERRIDE capability is
available to the following users:

          (1)  The President of the United States of America

          (2)  The Secretary of Defense and the Chairman of the
               JCS

          (3)  Commanders of Unified Commands

     b.   FLASH

FLASH call preempt IMMEDIATE, PRIORITY, and ROUTINE calls.
Listed below are examples of FLASH calls:

          (1)  Calls pertaining to command and control of
               military forces essential to defense and
               retaliation

          (2)  Critical intelligence essential to national
               survival

          (3)  Conduct of diplomatic negotiations critical to
               ceasing or limiting hostilities

          (4)  Dissemination of critical civil alert information
               essential to national survival

          (5)  Continuity of federal government functions
               essential to national survival

          (6)  Fulfillment of critical United States internal
               security functions essential to national survival

          (7)  Catastrophic events of national or international
               significance

     c.   IMMEDIATE

IMMEDIATE calls preempt PRIORITY and ROUTINE calls and are
reserved for communications pertaining to situations that gravely
affect the security of national and Allied forces.  Listed below
are some examples of IMMEDIATE calls:

          (1)  Reconstitution of forces in a post-attack period

          (2)  Intelligence essential to national security

          (3)  Conduct of diplomatic negotiations to reduce or
               limit the threat of war

          (4)  Implementation of federal government actions
               essential to national survival

          (5)  Situations that gravely affect the security of the
               United States

          (6)  Civil defense actions concerning the direction of
               the population and their  survival

          (7)  Disaster or events serious enough to have an
               immediate and detrimental  effect on the welfare
               of the population

          (8)  Vital information having an immediate effect on
               aircraft, spacecraft, or  missile operations

          (9)  Distress assistance

     d.   PRIORITY

PRIORITY calls preempt ROUTINE calls and are reserved for
communications requiring expeditious action by called parties
furnishing essential information for conducting government
operations.


     e.   ROUTINE

This precedence applies to official government communications
that require rapid transmission by telephonic means, but do not
require preferential handling.  A ROUTINE call does not preempt
any other call.
