MOBILE SUBSCRIBER EQUIPMENT (MSE)

The Mobile Subscriber Equipment MSE is considered an aging system and is currently being replaced by WIN-T. WIN-T is the key enabler to execute the NCW capability of the Army's Future Force. It is the "tactical digital communications system that will provide advanced commercial-based networking capabilities to the warfighter," replacing both the MSE and Tri-Services Tactical Communications (TRI-TAC) systems. The WIN-T network will provide enhanced C4ISR capabilities that are mobile, secure, survivable, seamless, and capable of supporting multimedia tactical information systems. The network's capability to support unit task reorganization and real-time retasking of battlefield support elements provides a vital enabler for the conduct of NCO.

Previous Information

The Mobile Subscriber Equipment (MSE) forms a network that covers an area occupied by unit subscribers. A typical grid is made up of four to six centralized Node centers which make up the hub or backbone of the network. Throughout the maneuver area, subscribers connect to local call switching centers by radio or wire. These switches, or extension nodes provide access to the network by connecting to the Node centers.

The MSE system provides communications in an area of up to 15,000 square miles. The system is digital, secure, highly flexible, and contains features that deal with link outages, traffic overload, and rapid movement of users.

The MSE system provides both voice and data communications on an automatic basis using a technique called flood search routing. The system supports both mobile and wire subscribers with the means to exchange communications, data, and intelligence information in a dynamic tactical environment. The Tactical Packet Network (TPN) portion of MSE is a packet switching network that is overlaid on the circuit switching network of MSE. Along with providing data communications, the TPN provides data interoperability with adjacent systems, including commercial networks.

Power Requirements: Diesel engine driven generators provide alternating current (AC) power throughout the system. In addition, vehicles equipped with 200-ampere alternators provide direct current (DC) power as backup during the initial setup of the system, as well as during maintenance, or refueling of the diesel engine generators.

SYNOPSIS: MSE SYSTEM WILL INTEGRATE THE FUNCTIONS OF THE USER TERMINAL EQUIPMENT, SWITCHING, RADIO TRANSMISSION, COMMUNICATIONS SECURITY AND CONTROL INTO ONE COMPOSITE COMMUNICATIONS SYSTEM. WHEN FIELDED, MSE REPLACED THE EXISTING SWITCHING COMMUNICATIONS SYSTEMS IN THE CORPS AND DIVISION AREAS.

ACQUISITION CATEGORY: III

ACQUISITION PHASE: MS III Production/Deployment

PE & LINE #: SSN: BB1610 & BB1611

DESCRIPTION: The MSE system will provide the tactical force with increased mobility and a discrete address capability to user. The functions of switching, radio trunking, communications security and system control will be integrated into one composite system, which will replace the existing command and area communications system in both the division and corps areas of operation. The MSE system will provide users with a means of communicating throughout the battlefield, regardless of location, in either a static or mobile situation. The system will significantly reduce the need to install wire and cable when establishing command posts. It will provide telephone-like, full-duplex operation for massed or dispersed command posts. The MSE system will consist of five major hardware functional elements: subscriber terminals; multiple subscriber access; wire subscriber access; area coverage; and system control.

TRANSPORTATION CHARACTERISTICS / LIMITATIONS: None.
