1. Purpose. This instruction establishes policy consistent with DODI 8100.3
(reference oo) and prescribes responsibilities for use and operation of the
DOD
voice networks, to include but not be limited to the Defense Switched Network
(DSN), the Defense RED Switch Network (DRSN), Defense Video Services (DVS)
and all Defense Information Systems Networks (DISN) that provide RTS.2. Cancellation. CJCSI 6215.01B, 23 September 2001, is canceled.
3. Applicability. This instruction applies to Office of the Secretary of Defense,
the Military Services, Chairman of the Joint Chiefs of Staff, combatant
commands, the Office of the Inspector General of the Department of Defense,
the Defense agencies, the DOD Field Activities and all other organizational
entities in the Department of Defense (referred to hereafter collectively as “the
DOD components”) in peacetime, crisis situations, and wartime. This
instruction also identifies policy and responsibilities concerning non-DOD
governmental, foreign government, and civilian organizational requests for
DSN, DRSN and DISN Assured RTS support (DARTS). Requests for waivers
this instruction will be forwarded through the DOD component chain of
command to the Joint Staff, stating the reason compliance is not possible.
This instruction is applicable to:
a. All telecommunications switches leased, procured (whether systems or
services), or operated by any DOD component of the Department of Defense.
b. The hardware or software for sending and receiving voice, data, or video
signals across a network that provides customer voice, data, or videoCJCSI 6215.01C

equipment access to the DSN, DRSN or public switched telephone networks
(PSTN).
c. End-to-End services (e.g., phone-to-phone, video-to-video units, fax-tofax;
secure terminal equipment (STE-to-STE) to include tactical applications.
d. All technologies i.e. (circuit switch, voice over Asynchronous Transfer
Mode (ATM), and Voice over Internet Protocol (VoIP)) that use DSN or DRSN
phone numbers; or that are otherwise incorporated into the DSN or DRSN
numbering or routing plans via area code, access code, Internet Protocol (IP)
addressing scheme, etc. for the origination and reception of voice, dial-up
video, and dial-up data for routine and precedence subscribers.
e. The DOD component's planning, investment, development, operations,
and management of telecommunications switches connected to the DSN or
DRSN for processing voice, dial-up video and dial-up data.
f. All networks that provide DISN RTS.4. Policy. T
he DISN provides RTS via its router networks (NIPRNET, SIPRNET
and the DISN Service Delivery Nodes) and via DSN, DRSN and DVS. DSN and
DRSN are worldwide private-line telephone sub-networks of the DISN that
provide long-haul secure and non-secure telecommunications services to DOD
component authorized users. They are the integral components of the Global
Information Grid (GIG) that provide End-to-End services to critical users at the
highest levels of Government. Connection approval shall follow the
instructions and processes in CJCSI 6211.02B (reference hh). Both DSN and
DRSN are under the management control of the Director, Defense Information
Systems Agency (DISA). As the single system manager (SSM) (reference oo), on
behalf of USSTRATCOM, for both networks and the executive agent (EA) of the
DRSN, the Director, DISA, will be responsive to the needs and requirements of
the Chairman of the Joint Chiefs of Staff (CJCS) and DOD components. This
policy supersedes CJCS messages dtg 171649Z Dec 2002 Interim Voice over IP
(VoIP), dtg 221621Z Oct 2004 Voice over Secure IP (VoSIP) Requirements.
Enclosures A, D, and E, provide policy for the DSN. Enclosures B, D, and E,
provide policy for the DRSN. Enclosure C, D, and E provide policy for RTS.
Specific responsibilities are outlined in Enclosure E.5. Definitions
a. The DSN is an inter-base, non-secure or secure DOD
telecommunications system that provides dedicated telephone service, voiceband
data, and dial-up video teleconference (VTC) for End-to-End command
use and DOD authorized C2 and non-C2 users in accordance with (IAW)
national security directives. Non-secure dial-up voice (telephone) service is the
system's principal service. (See references a and b)
CJCSI 6215.01C

b. The DRSN is a secure C2 system and is a key component of the DOD
global secure voice services. The DRSN supports secure voice and secure
conferencing requirements of the President, Secretary of Defense, Chairman of
the Joint Chiefs of Staff, DOD components, and select federal agencies in
peacetime, crisis situations, and wartime. It is a separate, secure switched
network that is considered part of the DISN. Three sub-services provide the
foundation for the DOD secure voice services: the DRSN, the secure telephone
unit-III/secure terminal equipment (STU-III/STE) and other secure
communications interoperability protocol (SCIP) equipment that provide Endto-
End encryption over the DSN, and other secure wireless products. (See
references c and d)
c.
The DISN is an integrated network, centrally managed and configured,
to provide telecommunications services for all DOD activities. This information
transfer service is designed to provide dedicated point-to-point; point-tomultipoint;
and switched voice, data, imagery, and VTC services in support of
national defense C3I decision support requirements (references e and oo).
For
GIG, Wide and Metropolitan Area Networking (WAN, MAN), use of the DISN is
mandatory unless granted a waiver from the GIG Waiver Panel (reference hh).
The DISN provides RTS via its circuit switched and IP router networks. These
networks include, but are not limited to: the DSN, DRSN, DISN, and the DVS
infrastructure, the DISN WAN to include the DISN SDN and access to those
SDN, Teleport, SIPRNET, and NIPRNET. The DISN’s underlying infrastructure
is composed of three major segments or blocks IAW CJCSI 6211.02B (See
reference hh):
(1)
The sustaining base (i.e., base, post, camp or station and
Service Enterprise Networks) command, control, communications, computers
and intelligence (C4I) infrastructure will interface with the long-haul network to
support the deployed warfighter. The sustaining base segment is primarily the
responsibility of the Services.(2) The long-haul telecommunications infrastructure, which includes
the communication systems and services between the fixed environment and
the deployed joint task force (JTF) and/or coalition task force (CTF) warfighter.
The long-haul telecommunications infrastructure segment is primarily
responsibility of DISA.
(3) The deployed warfighter and associated combatant commander
telecommunications infrastructures supporting the JTF or CTF. The deployed
warfighter and associated combatant command telecommunications
infrastructure is primarily the responsibility of Services.

d. RTSs are a subset of the four categories of services contained in the GIG
Net Centric Implementation Document (NCID) v2, Quality of Service (QoS)
(T300): Signaling, Inelastic/RTS, Preferred Elastic and Elastic.
(1) Signaling includes Network Control for managing the network.
(2) Inelastic /RTS provide GIG users with live interactive
telecommunications to include voice and video and the user signaling for
setting up and taking down sessions over the network. They also include rapid
delivery of critical C2 information involving weapons delivery capabilities.
Inelastic RTS allows for the equivalent of “Face to Face” interactions in which
both factual and emotional content of the interaction can be conveyed and the
operation of surveillance and weapons systems that require rapid message
delivery.
(3) Preferred Elastic services include services such as instant
messaging, user authentication imagery, video, and audio streaming.
(4) Elastic services include services such as, e-mail, web browsing, and
document transfers.
6. Responsibilities. See Enclosure E.
7. Administration. The DOD components must develop implementing policies
and procedures for the provisions of this instructions policy. The policies and
procedures must be coordinated with and provided to DISA to ensure that they
do not adversely affect network operation. Combatant commands must
validate DOD component policies.
8. Summary of Changes. The name of this instruction is changed from "Policy
for Department of Defense Voice Networks" to "Policy for Department of
Defense (DOD) Voice Networks with Real Time Services (RTS)". This includes
the use of (Internet Protocol) IP networks to transmit voice or video services
whether wired or wireless, tactical or strategic, Sensitive But Unclassified (SBU)
or Classified (reference oo). It also applies the emerging policies of the GIG
Mission Area Initial Capabilities Document JROCOM 095-04, 14 June 2004,
Key Performance Parameters to DISN RTS to support migration to a Net Centric
NetOps environment. Additionally, this revision updates DSN and DRSN
network performance parameters, cost recovery procedures, usage and security
policy, and enhancements to switches and terminal equipment. It updates the
definition of C2 users. It also incorporates guidance for the use of Enhanced
Mobile Satellite Service (EMSS) in conjunction with the DSN, as well as
numerous administrative and procedural changes.

direction for GIG NetOps and oversees collaborative coordination process
involving all CC/S/As, supporting the needs of the President, SECDEF, NetOps
Community, and the warfighting, business, and intelligence domains. (See
reference vv.)
Global NetOps Support Center (GNSC). The Global NetOps Support Center
(GNSC) provides the day-to-day technical operation, control, and management
of the portions of the GIG that support Global Operations but are not assigned
to a combatant command. The GNSC conducts GIG backbone NetOps, tactical
DISN extension via Standard Tactical Entry Point (STEP) and Teleport mission
support, provisioning of provided services, network engineering, circuit
implementation, and inter-theater connectivity among USNORTHCOM,
USPACOM, USEUCOM, USSOUTHCOM, and USCENTCOM areas of
responsibility. The GNSC provides General Support (GS) to the TNCs, and
provides DS to the GNCCs. (See reference vv.)
grade of service (GOS).
a. The probability of a call being blocked or delayed more than a specified
interval, expressed as a decimal fraction, (e.g. P.09 means nine calls out of 100
will be blocked). GOS may be viewed independently from the perspective of
incoming versus outgoing calls and is not necessarily equal in each direction.
GOS may be applied to the busy hour or to some other specified period or set of
traffic conditions.
b. In telephony the QoS for which a circuit is designed or conditioned to
provide; e.g., voice grade or program grade. Criteria for different grades of
service may include equalization for amplitude over a specified band of
frequencies, or in the case of digital data transported via analog circuits,
equalization for phase. (See reference jj.)

domestic population, and critical infrastructure against external threats and
aggression or other threats as directed by the President. (See reference bb).
installation. A grouping of facilities located in the same vicinity “which support
particular functions”. If a facility has a functions that is part of a DOD
organization’s mission, then it would be considered an installation. Example:
xi
DISA HQ and the Navy Annex have functions that are required organizational
functions and are considered installations.
Integrated Services Digital Network (ISDN). An integrated digital network in
which the same time-division switches and digital transmission paths are used
to establish connections for different services. ISDN services include
telephone, data, electronic mail, and facsimile. The method used to accomplish
a connection is often specified (e.g., switched connection, non-switched
connection, exchange connection, or ISDN connection). (See reference jj.)
Joint Worldwide Intelligence Communications System (JWICS). The sensitive
compartmented information portion of the Defense Information System
Network. It incorporates advanced networking technologies that permit pointto-
point or multipoint information exchange involving voice, text, graphics,
data, and video teleconferencing, also called JWICS (See reference bb.)
linear predictive coding (LPC). A method of digitally encoding analog signals,
which uses a single-level or multilevel sampling system in which the value of
the signal at each sample time is predicted to be a linear function of the past
values of the quantized signal. Note: LPC is related to APC in that both use
adaptive predictors. However, LPC uses more prediction coefficients to permit
use of a lower information bit rate than APC, and thus requires a more complex
processor. (See reference jj.)
maximum calling area (MCA). Geographic calling limits permitted to a
particular access line based on requirements for the particular line. Note:
MCA restrictions are imposed for network control purposes. (See reference jj.)
Multilevel Precedence and Preemption (MLPP). In military communications, a
priority scheme: a. for assigning one of several precedence levels to specific
calls or messages so that the system handles them in a predetermined order
and timeframe
b. for gaining controlled access to network resources in which calls and
messages can be preempted only by higher priority calls and messages
c. that is recognized only within a predefined domain
d. in which the precedence level of a call outside the predefined domain is
usually not recognized. (See reference jj.)
National Command Authorities (NCA). The President and the Secretary of
Defense or their duly deputized alternates or successors. (See reference bb.)

their national security emergency preparedness telecommunications functions.
The NCS consists of both the telecommunications assets of the entities
represented on the NCS Committee of Principals and an administrative
structure consisting of the EA, the NCS Committee of Principals, and the
Manager. (See reference p) b. The telecommunications system that results
from the technical and operational integration of the separate
telecommunications systems of the several executive branch departments and
agencies having a significant telecommunications capability. (See reference bb.)

to respond to and manage any event or crisis (local, national, or international)
that causes or could cause injury or harm to the population, damage to or loss
of property, or degrade or threaten the national security or emergency
preparedness posture of the United States. (See reference jj.)
Network Management (NM). The execution of the set of functions required for
controlling, planning, allocating, deploying, coordinating, and monitoring the
resources of a telecommunications network, including performing functions
such as initial network planning, frequency allocation, predetermined traffic
routing to support load balancing, cryptographic key distribution
authorization, configuration management, fault management, security
management, performance management, and accounting management. Note:
NM does not include user terminal equipment. (See reference jj.)
nodal switch. A tandem switch in the DSN that connects multiple EOs,
provides access to a variety of transmission media, routes calls to other nodal
switches, and provides network features such as MLPP. Nodal switches are
supervised by and interconnected to the DSN A/NM subsystem. The two types
of nodal switches in the DSN are:
a. stand-alone switch (SA). The SA functions solely as a tandem switch in
the DSN.
b. multifunction switch. This switch incorporates the combined functions
of an SA switch and an EO switch. No physical division exists between the EO
and SA functions within the MFS, but a logical division exists.
nonappropriated funds (NAF). Funds generated by DOD military and civilian

North America between Canada and Mexico.
off-hook.
a. In telephony, the condition that exists when an operational telephone
instrument or other user instrument is in use; (i.e., during dialing or
communicating). Note: Off-hook originally referred to the condition that
prevailed when the separate ear piece (receiver) was removed from its switch
hook, which extended from a vertical post that also supported the microphone
and connected the instrument to the line when not depressed by the weight of

Theater NetOps Center (TNC). Each TNC provides direct support to its TNCC,
ensuring the effective operation and defense of the GIG within the theater. The
TNC is OPCON to JTF-GNO and offers onsite, theater support. Each TNC can
issue technical directives to STNOSCs/Agency Theater Network Operations and
Security Centers (ATNOSCs). The TNC develops, monitors and maintains a
GIG SA view for the theater. The theater GIG Situational Awareness (SA) view
is aggregated and segmented based on requirements provided by the TNCC as
derived from the GIG common SA standards. The GIG SA view will include
pertinent theater, operational, and tactical-level system and network, GND,
and GCM status. Coordination with the TNCC is paramount especially with
regards to reporting requirements and SA. (See reference vv.)
Theater NetOps Control Center (TNCC). The primary mission of the TNCC is to
lead, prioritize, and direct theater GIG assets and resources to ensure they are
optimized to support the GCC’s assigned missions and operations, and to
advise the combatant command of the GIG’s ability to support current and
future operations. The specific roles of the TNCC include monitoring of the GIG
assets in their theater, determining operational impact of major degradations
and outages, leading and directing responses to degradations and outages that
affect joint operations, and directing GIG actions in support of changing
operational priorities. The TNCC leads the combatant command response to
NetOps events and responds to JTF-GNO direction when required to correct or
mitigate a global NetOps issue. (See reference vv.)
