MOS 31F Network Switching Systems Operator
The network switching systems operator-maintainer supervises, installs, operates, and performs systems maintenance on large and small electronic switches; system control centers; node management facilities; associated multiplexing and combat net radio interface (CNRI) equipment; short range line of sight radio systems; communications security (COMSEC) devices; and other equipment associated with network switching operations. Duties for MOS 31F at each skill level are:
a. Major duties.
(1) MOSC 31F1O. Installs, initializes, operates, and performs unit level and direct support maintenance on electronic switching assemblages, systems, and ancillary communications equipment. Uses computers to perform system/network operations. Interprets BIT/BITE and error codes to correct system faults. Installs, operates, performs strapping, restrapping, PMCS, and unit level maintenance on COMSEC devices. Operates and performs preventive maintenance checks and services (PMCS) on assigned vehicles. Installs, operates, and performs PMCS on power generators.
(2) MOSC 31F2O. Supervises, and performs as senior team member, in the installation, operation, employment, and direct support systems maintenance of large and small electronic switches and associated equipment. Performs and assists subordinate operators in the conduct of switching and COMSEC operations, Combat Net Radio Interface (CNRI) procedures, and associated computer related technical tasks. Interprets orders and compiles system statistics for the Shift or Node. Requests logistical support for switching teams or shifts. Implements network control center generated changes to support operational requirements. Assists in the conduct of preventive maintenance checks and services (PMCS) procedures on assigned vehicles and power generators.
(3) MOSC 31F3O. Supervises and performs complex and multifaceted switching operations functions. Supervises the installation, operation, deployment, provisioning, and maintenance of electronic switching assemblages or systems. Disseminates network orders, compiles operational statistics and reports, and processes requests for logistic support. Coordinates, integrates, and controls the operation of large and small electronic node switches with associated transmission systems and local network subscribers. Performs systems control center operations for the planning, configuration, and employment of switching equipment. Ensures contingency operations plans and routing subsystems are correctly maintained in the database to reflect current operational scenario. Troubleshoots complex system faults and supervises or corrects failures to meet system availability and reliability standards. Interprets operations orders affecting switching operations. Conducts switching technical, operational, and maintenance training of subordinates. Submits consolidated logistic and system status reports.
