Rhode Island Telecommunications System Technician (TST) License Exam — Summarized Coverage
The Rhode Island TST License Exam is administered under the Rhode Island Department of Labor and
Training and evaluates competency in low-voltage telecommunications systems installation, servicing,
testing, and troubleshooting in compliance with Rhode Island statutes, NEC standards, and structured
cabling regulations.
1. Rhode Island telecommunications licensing laws (TST, TSC, TSLI roles and limits)
2. Scope of work for a Telecommunications Systems Technician (installation, servicing, testing
under supervision rules)
3. OSHA safety standards (PPE, ladders, jobsite safety, electrical safety practices)
4. Basic electrical theory (Ohm’s Law, AC/DC principles, series and parallel circuits)
5. National Electrical Code (NEC) applications (especially Articles 90, 100, 250, 725, 800)
6. Grounding and bonding requirements for low-voltage systems
7. Structured cabling standards (TIA/EIA-568, 569, 570)
8. Copper cabling types, categories (Cat5e, Cat6, Cat6a), and termination practices
9. Fiber optic fundamentals (single-mode vs multimode, connectors, testing basics)
10. Coaxial cable systems and RF signal transmission basics
11. Telecommunications system types: voice, data, video, security, and sound systems
12. Network fundamentals (IP addressing basics, Ethernet, switches, PoE concepts)
13. VoIP and telephony systems (PBX, SIP basics, phone system infrastructure)
14. Signal transmission principles and interference/noise reduction
15. Blueprint and schematic reading for low-voltage systems
16. Installation practices (cable pulling, routing, conduit, raceways, labeling)
17. Equipment installation (racks, patch panels, enclosures, termination blocks)
18. Testing and troubleshooting tools (tone generators, cable testers, OTDR basics)
19. System commissioning and certification testing procedures
20. Power over Ethernet (PoE) standards and device powering principles
21. Low-voltage electrical classifications and separation from high-voltage systems
22. Fire stopping and penetration sealing requirements in structured cabling
23. Network infrastructure design basics (topology, switches, distribution systems)
24. Jobsite documentation, permits, inspection readiness, and compliance reporting
25. Communication systems grounding, surge protection, and lightning protection principles
26. Safety protocols for working in ceilings, risers, and confined telecom spaces
27. Troubleshooting common faults (signal loss, attenuation, crosstalk, continuity issues)
28. Professional responsibility under supervision of TST/TSC license holders
29. System maintenance, repair, and upgrade procedures
30. Scenario-based questions involving NEC compliance, cable installation errors, troubleshooting
faults, safety violations, and selecting correct installation or testing methods

1.
Under Rhode Island TST scope of work, which activity is most appropriate for a licensed
Telecommunications Systems Technician?
A. Installing high-voltage electrical service panels independently
B. Installing and testing low-voltage structured cabling systems under applicable supervision rules
C. Designing structural building foundations
D. Performing unrestricted electrical utility work
Answer: B
Rationale: TST technicians are limited to low-voltage telecommunications work under defined
supervision rules.
2.
Which OSHA requirement is most critical when working on elevated ladders during cable installation?
A. Wearing hearing protection only
, Page 3 of 123
B. Using proper ladder safety procedures and fall prevention practices
C. Removing all PPE for better mobility
D. Working alone without supervision
Answer: B
Rationale: Ladder safety and fall protection are essential OSHA compliance requirements.
3.
What is the primary purpose of grounding and bonding in telecommunications systems?
A. Increase data transmission speed
B. Protect equipment and personnel from electrical surges and faults
C. Reduce cable length requirements
D. Improve Wi-Fi signal strength only
Answer: B
Rationale: Grounding and bonding safely dissipate electrical faults and surges.
