| | Defense Red Switch Network (DRSN) |
| | Primary Purpose | The DRSN provides secure command and control |
| | switches which offer high-quality secure voice |
| | and conferencing capabilities to the senior |
| | decision makers and staff of the National Command |
| | Authorities (NCA), the Commanders in Chief |
| | (CINCs), Major Commands (MAJCOMs), other |
| | Government departments and agencies, and Allies. |
| | Sub-Functions | The DRSN also provides secure voice conferencing |
| | and access to secure strategic, tactical, |
| | airborne, and seaborne equipment and platforms. |
| | Equipment Requirements | The DRSN consists of four major subsystems: the |
| | Switching Subsystem, the Transmission Subsystem, |
| | the Timing and Synchronization Subsystem, and the |
| | Network Management Subsystem (NMS). |
| | |
| | Switching Subsystem: |
| | The DRSN Switching Subsystem provides the DRSN |
| | users secure and nonsecure call origination and |
| | call termination capabilities, secure |
| | conferencing, and direct interoperability with |
| | other secure networks. The primary switching |
| | platform of the DRSN Switching Subsystem is the |
| | Raytheon family of secure digital switches. In |
| | most DRSN switch locations, both a RED switch and |
| | a BLACK switch are installed to provide |
| | integrated RED/BLACK service (i.e., users are |
| | provided a single telephone instrument with which |
| | they can access both secure networks and |
| | nonsecure networks). |
| | |
| | Transmission Subsystem: |
| | The DRSN Transmission Subsystem provides |
| | connectivity between DRSN RED switches, |
| | connectivity between a DRSN RED switch and users |
| | located remotely from the switch, and |
| | interconnection with other secure networks and |
| | systems. The Transmission Subsystem includes |
| | Network Equipment Technologies, Inc. (N.E.T.) |
| | IDNX and Promina multiplexing equipment, |
| | encryption devices, channel service units (CSUs), |
| | and tail segment cabling. The Transmission |
| | Subsystem connects the DRSN RED switches to |
| | Government-owned and leased backbone transmission |
| | systems. |
| | |
| | Timing and Synchronization Subsystem: |
| | The T&S Subsystem provides a primary, secondary, |
| | and tertiary method of obtaining a timing source |
| | for site contingency and the network. The T&S |
| | system is comprised of reference clocks, clock |
| | distribution systems, and RED/BLACK isolation |
| | filters and buffers. |
| | |
| | Network Management Subsystem: |
| | The NMS provides DISA with the capabilities to |
| | provide day-to-day direction and operational |
| | oversight of the DRSN. It includes the |
| | facilities, equipment, organizational structure, |
| | and people to monitor and interface with the DRSN |
| | site O&M activity to affect problem resolution. |
| Connectivity Requirements | T1 or E1 transmission systems, fractional T1 |
| (FT1) transmission links, and 56 or 64 kilobits |
| per second (kb/s) transmission links. |
| Crypto Requirements | KG-94/94A, KIV-7/HS. |
| Normal Locations | The DRSN is located with the NCA, the National |
| Military Command Center (NMCC), combatant |
| commands, the Services, subordinate organizations |
| (military and civilian), and Allies (North |
| Atlantic Treaty Organization (NATO), Canada, |
| etc.), both locally and worldwide. |

| Manager for the DRSN, is responsible for |
| providing operational direction and management of |
| worldwide DRSN assets. |
