Nodal Network Systems Operator-Maintainer

Primary Duties: The Nodal Network Systems Operator-Maintainer supervises, installs, operates, and performs field level maintenance on IP-based high speed electronic nodal systems; integrated network control centers; network management facilities; associated multiplexing and transit cased subscriber interface equipment; Communications Security (COMSEC) devices; and other equipment associated with network nodal operations. Performs network management functions in support of maintaining, troubleshooting and re-engineering of nodal assets as needed in support of operational requirements.

Skill Level 1 Install, initialize, operate, and perform field level maintenance on electronic nodal assemblages, combat net radios, and ancillary communications equipment. Use computers and software tools to perform system/network operations. Interpret system and equipment error codes to correct system faults. Install, operate, maintain, and perform Preventative Maintenance Checks and Services (PMCS) and perform unit level maintenance on all internal communications systems and COMSEC devices. Operate and perform PMCS on assigned vehicles. Install, operate, and perform PMCS on power generators. Perform as network controller in Brigade Combat Team Network Operations (BCT NETOPS) section. Execute the installation, operation, PMCS and field level maintenance of the Integrated System Control (ISYSCON), Joint Network Management System (JNMS), Detailed Planning and Engineering Module (DPEMS) or any other associated network management systems.

Skill Level 2 Supervise and perform as team chief or team member, in the installation, operation, employment, and field level maintenance on electronic IP based nodal assemblages and associated equipment. Perform and assist subordinate operators to execute nodal and COMSEC operations, associated computer and software related technical tasks. Interpret orders and compile system statistics for the shift and node. Assist in reconfiguration of IP-based nodal systems equipment as needed. Request logistical support for teams or shifts. Implement network operations center generated changes to support operational requirements. Direct or assist in conducting PMCS procedures on assigned vehicles, power generators, combat net radios, and all other associated internal nodal communications systems.

Skill Level 3 Supervise and perform complex and multifaceted nodal operations functions. Supervise the installation, operation, deployment, provisioning, maintenance of electronic IP based nodal assemblages, combat net radios and all related COMSEC devices. Disseminate network orders, compile and submit operational statistics reports and processes requests for logistic support. Coordinate, integrate, and control the operation of IP-based nodal systems with associated transmission systems and local subscriber interface equipment. Perform network operations center tasks for planning, reconfiguration, and employment of nodal systems equipment. Ensure contingency operations plans and nodal routing subsystems are correctly maintained in nodal databases to reflect current operational scenarios. Troubleshoot complex system faults, supervise or correct failures to meet system availability and reliability standards. Interpret, disseminate, and implement network changes/reconfigurations affecting nodal network architecture operations. Execute or supervise in the installation, operation, PMCS, and field level maintenance on all associated network management equipment or systems. Conduct technical, operational, and maintenance training of subordinates on nodal operations procedures.
