25L: Cable Systems lnstaller - Maintainer

Major Duties: The cable systems installer–maintainer installs, operates, and performs unit level maintenance on cable and wire communications systems, communication security (COMSEC) devices, and associated equipment. Operates and performs Preventive Maintenance Checks and Services (PMCS) on assigned vehicles and power generators. Duties for MOS 25L at each level of skill are:

• Skill Levels
  • Skill Level 1 MOSC 25L1O. Installs, operates, and performs unit level maintenance on cable and wire systems, to include Digital Group Multiplexers (DGM), Remote Multiplexing Combiners (RMC), repeaters, restorers, voltage protection devices, telephones, test stations, intermediate distribution frames, and related equipment. Configures DGM and RMC for operations. Installs, operates, performs strapping, restrapping, PMCS and unit level maintenance on COM-SEC devices. Performs tests on cable communications systems to ensure circuit and system quality. Tests circuits/groups to detect and locate line faults. Operates manual and motorized cable construction equipment. Climbs poles, as necessary, and assists in the construction of tactical cable and wire lines. Clears and maintains rights of way. Recognizes electronic countermeasures and applies appropriate electronic counter-countermeasures as necessary. Operates and performs PMCS on telephone line and other vehicles. Installs, operates, and performs PMCS on power generators.
    
    
  • Skill Level 2 MOSC 25L2O. Coordinates and supervises team member activities in the construction, installation, and recovery of cable and wire communications systems and auxiliary equipment. Coordinates remote trunking operations with switching central personnel. Interprets and updates line route maps and overlays. Coordinates team logistic requirements. Checks and performs PMCS and unit level maintenance on wire and cable systems and associated communications equipment. Ensures PMCS and maintenance functions are performed in accordance with published schedules.
    
    
  • Skill Level 3 MOSC 25L3O. Supervises and coordinates all phases of construction, recovery, and maintenance of cable and wire distribution systems and associated multiplexing, reeling, and testing equipment, including telephones. Estimates time, supplies, personnel, and equipment required to construct cable and wire communications systems. Assigns work crews and coordinates activities of personnel to meet workload demands. Inspects pole line construction and cable and wire lines and equipment to ensure approved construction and risk assessment standards are met. Supervises and checks maintenance performed by subordinate personnel. Prepares line route maps and overlays. Interprets circuit diagrams and operations order extracts. Prepares and conducts MOS and unit training programs. Advises the commander on cable and wire system operations. Supervises section and team deployment of individual and crew-served weapons for site defense. Employs and enforces principles of COMSEC, SIG-SEC, OPSEC, and physical security.
