CHIEFS OF STAFF

INSTRUCTION

J-6 CJCSI 6215.01C

DISTRIBUTION: A, B, C, J, and S 9 November 2007

POLICY FOR DEPARTMENT OF DEFENSE (DOD) VOICE NETWORKS WITH

REAL TIME SERVICES (RTS)

Reference(s): See Enclosure F.

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 video

CJCSI 6215.01C

9 November 2007 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-to-fax; 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. The 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, voice-band 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)

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 End-to-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-to-multipoint; 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.

9. Releasability. This instruction is approved for public release; distribution is unlimited. DOD components, other federal agencies, and the public may obtain copies of this instruction through the Internet from the CJCS Directives Home Page -- http://www.dtic.mil/cjcs_directives.

10. Effective Date. This Instruction is effective immediately upon receipt.

ENCLOSURE A

POLICY FOR THE DEFENSE SWITCHED NETWORK (DSN)

1. Purpose. This enclosure provides general guidance, usage, and performance objectives for the DSN. In addition, it describes functional requirements and military-unique features of the DSN.

2. General

a. The DSN is a rapid, reliable, survivable, telecommunications network serving DOD authorized users. The DSN is a sub network of the DISN and GIG. The basic DSN is a worldwide hierarchal network of telecommunication switches to which end instruments are connected. It provides rapid, reliable, survivable, non-secure, secure, and economical C2 telecommunications to selected users. To take advantage of economies of scale, the DSN also provides service to non-C2 users as long as the primary mission supporting C2 users is not impacted.

b. The USSTRATCOM/JTF-GNO Global NetOps Center (GNC), DISA Global NetOps Support Center (GNSC) thru the Theater NetOps Centers (TNC) provide high-level monitoring and situational awareness of the core DSN infrastructure 24 hours a day, 7 days a week. These centers implement the DSN service manager's authority and responsibility to take immediate and necessary action to perform network-level fault isolation or restoral actions in the event of outages, network compromise, or critical world situation. GNC, GNSC and TNC roles in monitoring and situational awareness of connectivity to allies will be limited to the terms agreed upon in the memorandum of agreement/memorandum (MOA/MOU) of understanding that governs the allied connections to the DRSN. This will be determined on a case-by-case basis.

c. The integral components of the DSN and connections to the Deployable Voice Exchange (DVX) are under the DISA SSM, on behalf of USSTRATCOM, and have direct management control for day-to-day peace time and crisis operation of the DSN long haul terminations. Configuration Management (CM) and Information Assurance (IA) are shared responsibilities. Integral components are the stand alone(SA), Multifunction, end office (EO), and Small End Office (SMEO) switches including versions of these switches with Time Division Multiplexing (TDM) trunks and VoIP on the line side, as well as the End-to-End IP-based RTS addressed in Enclosure C.

d. The user equipment (PBXs, DVXs, and end instruments) connects to the DSN at an EO switch in order to reach the worldwide DSN backbone. All DSN on-net equipment, to include elements controlled and managed by the Military Departments such as PBXs, DVXs, deployable/tactical switches, and user

A-2 Enclosure A terminal equipment, are considered part of the GIG and must meet End-to-End interoperability, functionality and IA requirements IAW DOD directives and CJCSIs. (See references e, f, hh, qq and rr)

e. The DSN is to be used only for official business or in the interest of the US Government and the first choice for all switched voice and dial-up video telecommunications between DOD user locations per DODI 8100.3. (See reference oo). All DOD long-haul communications requirements will be submitted to DISA IAW DODI 4640.14 (reference gg). DISA will use the appropriate DISN service to satisfy DOD long-haul and wide-area network information transfer requirements. Other systems shall not be used to “bypass” DSN unless the Joint Staff provides a waiver IAW reference z.

f. The primary function of the DSN is to provide non-secure dial-up voice service. Enclosures A, B, and C outline policy and procedures for connection of specific equipment to the DSN and procedures to obtain switched voice non-secure service for DSN users.

g. The DSN provides, via STU, STE, and other SCIP terminal equipment, an additional source of secure communications for DRSN users. A direct interface between DSN to DRSN allows DRSN communications to be extended to C2 users that are connected to DSN EOs.

3. Cost Recovery under DISN Subscription Services (DSS). The Office of the Secretary of Defense (OSD) directed a cost recovery program based on site subscription fees for DISN services. This program, part of a DSS, began implementation in FY06.

(1) The DISN subscription charge is based on bandwidth and actual DISN services provided from the DISN Subscription locations to the users’ infrastructure. The customer (host, tenant, or remote user) is responsible for the costs of getting to the DISN meet-me-point (i.e., the DISN or commercial demarcation point) from the user’s infrastructure. Validated requirements must be provided to the DISN Customer Forum (DCF) to ensure they are incorporated in the DOD components DSS provided for their specific locations.

All questions regarding this process should be directed to the DOD component representative on the DCF.

(2) Customer requirements (Subscription Bandwidth Allocation plus a term of services), including DSN services, are aggregated at each DISN Subscription location and represented by a single weight factor. Currently, there are four DISN Subscription Bandwidth Allocation choices and five DSS Packages. The current combination of Subscription Bandwidth Allocation and DSS Packages results in a matrix of twenty service options. Weight factors are based on both increasing bandwidth allocation and services provided.

A-3 Enclosure A

4. Usage Policy. General DOD components use of the DSN is restricted to the official business of the US Government or in the interest of the US Government. Local commanders have the approval authority for long distance services on the DSN. (See reference oo)

a. DSN is the official DOD components switched voice network and will be the first choice communications means for all Special C2, C2, and non-C2 users. It is the primary means of secure (STU-III STE/SCIP family) communications for non-tactical C2 users. DSN must be the user’s first choice; however, if DSN is not immediately available, or if the called party does not have access to DSN service, other long-distance calling methods may be used. DOD components shall not install or otherwise implement other long haul voice networks to permanently “BY PASS” primary DSN telecommunications in accordance with (IAW) reference z.

b. The DOD may grant non-DOD activities access to DSN when necessary for national security; when not in conflict with US Government rules and regulations or OCONUS local post, telephone and telegraph (PTT) ordinances;

when those activities and individuals have critical National Security or Emergency Preparedness (NS/EP) needs; and access is in the best interest of the US Government IAW reference oo. If access is approved, DSN services are provided on a cost-reimbursable basis (normally charged to the non-DOD requester through OSD; however, reimbursement may be made through the sponsoring DOD Component). In CONUS, requests for telephone service by non-DOD users should be satisfied by available commercial service and US General Service Administration (GSA), Federal Telecommunications Services (FTS) 2001 (or the successor services, Networx Universal) if the use is clearly not associated with the military mission of the Department of Defense. When in the best interest of the US Government, access to the DSN can be provided on a not-to-interfere basis (i.e., does not affect the DOD mission).

Requirements to support non-DOD or non governmental activities or agencies, such as the Department of Justice, state government organizations, DOD contractors, labor unions, and foreign embassies, will be validated by the Joint Staff and referred to OSD for approval, except as provided in Paragraph 3e below.

c. Health, Morale and Welfare (HMW). IAW reference mm, when approved by theater commanders in the interest of HMW, DSN may be used by military members and other DOD employees who are deployed outside CONUS for extended periods on official DOD business. DSN may be authorized, within and outside CONUS, by military members who, although are no longer directly supporting a contingency operation, are hospitalized as a result of wounds or other injuries incurred while serving in direct support of a contingency operation. (See reference xx) combatant commands will establish policy for

A-4 Enclosure A authorization, management control, frequency, and duration of HMW calls to be compatible with operational requirements, local restrictions, and host-nation laws or agreements. The following conditions apply to HMW use of

DSN:

(1) Calls will have management controls that prevent unauthorized use of the DSN and other public networks (PSTN, PTT etc.), or through the DISA-managed interface to the PSTN as described in Enclosure A, Appendix A., 7.f.(2) (c). To ensure compliance with reference mm, technical means will be implemented to prevent completion of CONUS-originated calls.

(2) Calls should be placed only during normal non-duty hours at the originating location and, where possible, timed to avoid the normal duty period at the terminating location.

(3) Calls must be placed only at the ROUTINE precedence and normally should not exceed 15 minutes in duration. No off-net HMW call will incur a toll charge to the US Government, even if the intent is to reimburse the US Government. An off-net HMW call that would incur a commercial toll charge may be placed if the called party agrees to accept the charges on a collect call basis or some other means of assured payment such as a credit card.

d. Netting. Interconnection of long-distance (originating at another switch) DSN calls with a local or long-distance commercial network (on or off-netting) are only allowed for the following purposes:

(1) Operations support. A combatant command (Command Authority), also known as COCOM, Service Chief, or director of a Defense agency may authorize automatic or manual official long-distance telephone traffic for personnel to maintain contact with their office and carry out their responsibilities.

(2) Emergencies, Special Circumstances. On and off-netting of official long-distance telephone traffic by automatic or manual interfaces is authorized for crisis or national emergency conditions. Additionally, off-netting is authorized to support DOD operational requirements via the PSTN to authorized wired or wireless terminals.

(3) Control. OCONUS combatant commands must establish procedures to positively control all on and off-net access within their area of responsibility (AOR). DOD components will establish procedures for positive control of all on and off-net access in CONUS.

e. Non-DOD Agencies

A-5 Enclosure A

(1) American Red Cross (ARC). Access to the DSN is provided to the ARC in support of cases involving military members, DOD civilians, and their families. Global access at ROUTINE precedence is authorized.

(2) Contractors.

(a) US civilian contractor personnel in overseas areas may use the DSN when they are performing duties normally performed by DOD civilian or military personnel. Foreign national contractors may be authorized DSN access when validated by the appropriate DOD component and approved by the Joint Staff. Only DSN calls directly related to and necessary for the accomplishment of contracted duties are permitted between an overseas location and CONUS or within an overseas theater.

(b) US Contractor personnel within CONUS may use the DSN when performing a mission normally performed by DOD civilian or military personnel, subject to the following:

1 The contractor’s function is supporting a C2 mission.

2 DSN access provided to the contractor is equivalent to that access previously provided to the military organization originally performing the function. Study, analysis, design engineering, and other similar support functions are not missions requiring C2 access. Requests for ROUTINE access must be validated at the local level and approved by an agent with written delegation from the appropriate DOD component. Precedence access above ROUTINE must be approved by the DOD.

3 Contractors located in CONUS requiring new or increased DSN access must have each specific request approved by the appropriate DOD component. Blanket approvals are not authorized.

(c) The requesting DOD component must validate the requirement and certify that contract documents contain guidance and restrictions, certified by the contracting officer, ensuring contractor use of DSN complies with established Network Management (NM) procedures. Requests for approvals must identify the contract termination date.

(d) Procedures for reviewing, monitoring, and controlling contractor access to DSN have been published in DOD component or command regulations. As a minimum, contractor access to DSN is reviewed every 3 years and in conjunction with every renewal or period of performance extension of the contract.

A-6 Enclosure A

(e) Copies of all contractor access requests, approvals, and terminations are provided through the contracting officer to DISA, DSN SSM.

(f) Approvals and contracts must state that the DOD has the right to terminate the DSN service at any time and DOD does not guarantee the quality or quantity of service to be supplied and cannot be held liable for any discontinuance or failure of the service.

f. DSN Service for personnel supporting Non- US functions. The use of DSN IMMEDIATE, PRIORITY AND ROUTINE precedence by DOD personnel assigned to non-US (foreign government adviser, UN, NATO, etc.) organizations must be approved by the appropriate DOD component. Requests for FLASH or FLASH OVERRIDE must be validated by the appropriate DOD component and approved by the Joint Staff.

g. DSN Service to Canada. Use of the DSN by Canadian Defense Forces is authorized as an extension of the Canadian Switch Network (CSN) for combined cross-border C2 communications in support of their worldwide mission.

h. Foreign Governments and Treaty Organizations. Foreign government activities may be granted access to the network by the DOD for purposes of national security and when not in conflict with existing agreements or local PTT ordinances. This access must be initiated by, and processed through, the appropriate DOD sponsor IAW reference n. Combatant commands may authorize the use of DSN in his/her AOR, at ROUTINE precedence, by personnel of friendly foreign governments or treaty organizations for discussion of official US Government business with US personnel, if such use will not reduce the grade of service (GOS) objectives outlined in this instruction.

Combatant commands must ensure effective control of this use and may authorize the service only when other telecommunications systems are unavailable or unsatisfactory. If the DSN access required by personnel of friendly foreign governments or treaty organizations becomes routine or becomes a formal requirement, the arrangement must be formalized by an international agreement. (See reference n)

i. Foreign Military Sales (FMS). Use of DSN service may be approved as part of an FMS arrangement. Requests for DSN service for non-US or non- DOD users must be submitted through the Joint Staff to OSD (NII). (See reference t).

j. Labor Unions. Access to DSN is not normally provided to labor unions and is not routinely authorized in contract documents. The basis for supporting a request to OSD must be a clearly operational, military-related

A-7 Enclosure A function. The Joint Staff, DOD components, and DISA will be notified of command support for a request to OSD for labor union access to DSN.

k. Non-appropriated Fund (NAF) Activities. NAF activities may be authorized to use the DSN to conduct command management functions dealing with appropriated funds matters. Local commanders are responsible for approval and control of NAF access and requirements, ensuring DSN use is on a cost-reimbursable basis. The DOD components must institute procedures to revalidate requirements periodically.

l. Residential Services. When normal commercial service is either unavailable or unreasonably expensive, DOD employees (excluding contractors) may be provided DSN access/lines at overseas locations only on a cost-reimbursable basis. Local commanders may request this service, for geographic location(s) within his or her command. Requests must be forwarded to the combatant command for approval/disapproval and to the DISA DSN program management office (PMO) for information. Approved Class B service must be revalidated by the combatant command biennially. Local commanders are responsible for determining appropriate cost reimbursement rates (reference u). In addition, DSN service may be provided in residences of key personnel for official calls.

m. Commercial Leased Transmission. The DSN may use commercial leased transmission facilities when cost-effective or mission-essential requirements dictate. Commercial leased transmission facilities in overseas areas are negotiated country-by-country by the DISA, IAW the appropriate combatant commands and operations and maintenance (O&M) commanders.

5. Objective Technical Parameters and Special Functions

a. Network Performance Objectives. Network performance objectives aimed at providing DSN services to satisfy the system requirements and reduce costs are recommended by DISA in coordination with the DOD components. They must be validated by the Joint Staff and approved by ASD (NII)/DOD (CIO).

Performance objectives employ commercial standards and practices, when practical, to satisfy mission requirements. The objective for ROUTINE precedence calls traversing the network from an EO instrument is a peacetime theater GOS of P.07 (P.07= probability of seven calls out of 100 will be “blocked” during the “busy hour”) or better, and an inter-theater GOS of P.09 or better, as measured during normal business hours of the theaters. DOD component O&M commands will ensure the GOS between the EO and any PBX users do not exceed an additional blockage of P.02. DOD component O&M commands are responsible for supporting DISA’s data collection requirements on all DSN switches. DOD component O&M commands will report, to DISA, any user locations where GOS objectives cannot be achieved behind the EO

A-8 Enclosure A due to economic or operational limitations. DISA then compiles the data into monthly reports showing GOS across the DSN.

(1) DISA will report to the Joint Staff and respective combatant commands, those network access points (EOs and multifunction switch (MFS)) that do not meet the following performance standards:

(a) GOS criteria for inter-theater of P.09.

(b) Theater objective of P.07 as measured during the normal business hours between the DSN locations. (combatant commands may waive specific theater EO ROUTINE GOS implementations after coordination and consideration of DISA’s network impact assessment.) The Joint Staff must be notified of all waivers of the theater GOS objective by the combatant command, and these waivers must be revalidated every 2 years.

(c) Any EO not meeting the special C2 user (DSN multilevel precedence and preemption (MLPP) FLASH OVERRIDE and FLASH) non-blocking criteria.

(2) Combatant commands report shortfalls in achieving the above target-GOS criteria because of economic or operational reasons to include shortfalls behind EOs.

b. Voice Quality. Because intelligibility of voice communications is critical to C2, the DSN voice service quality rating on at least 95 percent of the voice calls will have a mean opinion score (MOS) IAW the DOD Information Technology Standards Registry (DISR) (reference nn) shown in Table 1.

Configuration Objective MOS Fixed to Fixed 4.0 Fixed to Tactical 3.6* Tactical to Tactical 3.2

Table 1. Voice Quality Objective Mean Opinion Score

* As is specified in Appendix 2 of the Generic Switching Center requirements

(GSCR)

c. Voice Technology Migration. The DSN SSM is designated as the voice standards and voice processing/transport technology migration coordinator to ensure End-to-End global voice quality, interoperability, and visibility for all voice C2 services. As such, all DOD component installation (base, post, camp, or station) voice transport and processing initiatives shall be coordinated with the DSN SSM. The DSN SSM will provide an annual assessment of the impact of emerging voice processing/transport technologies on global End-to-End voice performance and C2 services to the Joint Staff and the DSN CCB.
