Note differences in wire and cable colors so that work can be performed correctly. Test circuits and components of malfunctioning telecommunications equipment to isolate sources of malfunctions, using test meters, circuit diagrams, polarity probes, and other hand tools. Test repaired, newly installed, or updated equipment to ensure that it functions properly and conforms to specifications, using test equipment and observation. Drive crew trucks to and from work areas. Inspect equipment on a regular basis in order to ensure proper functioning. Repair or replace faulty equipment such as defective and damaged telephones, wires, switching system components, and associated equipment. Remove and remake connections in order to change circuit layouts, following work orders or diagrams. Demonstrate equipment to customers and explain how it is to be used, and respond to any inquiries or complaints. Analyze test readings, computer printouts, and trouble reports to determine equipment repair needs and required repair methods. Adjust or modify equipment to enhance equipment performance or to respond to customer requests. Request support from technical service centers when on-site procedures fail to solve installation or maintenance problems. Remove loose wires and other debris after work is completed. Assemble and install communication equipment such as data and telephone communication lines, wiring, switching equipment, wiring frames, power apparatus, computer systems, and networks. Communicate with bases, using telephones or two-way radios to receive instructions or technical advice, or to report equipment status. Collaborate with other workers in order to locate and correct malfunctions. Review manufacturer's instructions, manuals, technical specifications, building permits, and ordinances in order to determine communication equipment requirements and procedures. Test connections to ensure that power supplies are adequate and that communications links function. Climb poles and ladders, use truck-mounted booms, and enter areas such as manholes and cable vaults, in order to install, maintain, or inspect equipment. Refer to manufacturers' manuals to obtain maintenance instructions pertaining to specific malfunctions. Designate cables available for use. Run wires between components and to outside cable systems, connecting them to wires from telephone poles or underground cable accesses. Remove and replace plug-in circuit equipment. Route and connect cables and lines to switches, switchboard equipment, and distributing frames, using wire-wrap guns or soldering irons to connect wires to terminals. Clean and maintain tools, test equipment, and motor vehicles.
