1. Field Planning, Implementation and Design
15% of the INSTC written exam: copper cable properties and types, interpreting blueprints, inventorying job supplies, verifying the site safety plan and labeling to a scheme.
Key facts
- Category 5e, 6 and 6A are specified to 100, 250 and 500 MHz, and 10GBASE-T needs Category 6A for a full 100 m channel.
- Horizontal cable is usually 23 or 24 AWG solid copper with four twisted pairs.
- T568A and T568B differ only in pairs 2 and 3. Use one scheme for the whole project.
- 25-pair binders use tip colors white, red, black, yellow and violet with ring colors blue, orange, green, brown and slate.
- To estimate cable, divide the box by the average run and round down, then divide the outlets by whole pulls and round up.
- Read the title block, scale, legend and notes on a drawing before measuring anything.
- The site safety plan comes before the schedule: PPE, ladders, lifts and lockout/tagout.
- Labels follow the ANSI/TIA-606 scheme named by the job, at both cable ends and every termination.
Flashcards
Exam tip: Copper planning items reward careful arithmetic. Round pulls down and boxes up, and read the scale before you measure.
2. Pathways and Spaces
28% of the INSTC written exam: telecommunications spaces, bonding infrastructure, cable supports, outlets at walls, floors, furniture and other locations, cut-in rings, sleeves, poke-throughs, trays and raceways, and firestop.
Key facts
- Conduit: no more than 30 m (100 ft) and two 90-degree bends between pull points.
- Conduit bend radius is 6 times internal diameter up to 53 trade size (2 in.) and 10 times above that.
- Use 40% fill for three or more cables in conduit and always round down.
- Space noncontinuous supports no more than 1.5 m (5 ft) apart.
- Don't lay cable on ceiling tiles; keep at least 75 mm (3 in.) above them.
- Bonding connections need clean metal, antioxidant where required and listed two-hole compression lugs.
- A cut-in ring is used on existing drywall where no box is present.
- Firestop must match a listed system for the barrier, opening and penetrant, and must be restored after changes.
Flashcards
Exam tip: Pathways is the largest area on this exam. Ask whether each option protects the cable, keeps the fire rating and follows a listing.
3. Pulling Copper Cable
14% of the INSTC written exam: pull setup, pull strings and ropes, horizontal pulls in conduit and open ceilings, and riser and horizontal backbone pulls.
Key facts
- Maximum pulling tension for one 4-pair cable is 110 N (25 lbf).
- Minimum inside bend radius for 4-pair cable is 4 times the outside diameter.
- Use a breakaway swivel or tension monitor where the tension could approach the limit.
- Inspect conduit ends and fit bushings to protect the cable from sharp edges.
- Lubricant must be compatible with the jacket; check the manufacturer's data.
- Pulling from the top down helps in risers; secure the cable as it descends.
- Leave the slack the job plan requires at the room and the outlet.
Flashcards
Exam tip: If a pull is stuck, stop and find out why. Adding force is almost never the right option.

4. Terminating and Splicing Copper
19% of the INSTC written exam (terminating 14%, splicing 5%): pre-termination, connecting hardware, multi-pair and four-pair IDC, coaxial and modular plug termination, and copper splicing.
Key facts
- Keep pair twist to within 13 mm (0.5 in.) of the contacts on Category 5e and higher.
- Remove only as much jacket as the connector needs, and don't nick the insulation.
Flashcards
Exam tip: Check the sequence: jacket, untwist, pair order, seat and trim. Exam errors are usually one bad step.
5. Testing Copper Cable
6% of the INSTC written exam: copper cable testing, including permanent link and channel certification and the parameters a field tester reports.
Key facts
- A permanent link excludes end cords and may be up to 90 m.
- A channel includes cords and may be up to 100 m.
Flashcards
Exam tip: Match the limit to the setup first. A correct measurement against the wrong limit still fails the job.
6. Troubleshooting Copper Cable
6% of the INSTC written exam: copper cable troubleshooting, including wire map faults, crosstalk and return loss failures.
Key facts
- An open has a broken conductor; a short connects two conductors.
- A reversed pair swaps the two wires within one pair.
Flashcards
Exam tip: Match the symptom to the layer: continuity for pin faults, NEXT for twist faults, return loss for impedance faults.
7. Retrofits and Integration
9% of the INSTC written exam (retrofits 4%, integration and convergence 5%): identifying active circuits, cutovers, removing abandoned cable, topologies, network components, security, wireless and other building systems.
Key facts
- Confirm that a circuit is inactive and get owner release before removal.
- A cutover needs a schedule, pretesting and a rollback plan.
Flashcards
Exam tip: Retrofit answers put service continuity first. If an option could interrupt something live, it's probably wrong.
8. Codes and Standards
3% of the INSTC written exam: adhering to local, state and federal fire and building codes and applicable standards.
Key facts
- The AHJ decides how codes apply on the site.
- Communications cable hierarchy: CMP, then CMR, then CMG or CM, then CMX.
Flashcards
Exam tip: On substitution questions, remember that listings only move up. A better listing can replace a lower one, never the reverse.
How to pass
- Pathways and spaces are 28% of the written exam, the largest single area. Expect supports, outlets, sleeves, bonding and firestop, not just copper work.
- BICSI suggests 50 hours of independent ITSIMM study. Spend them in proportion to the outline: pulling and terminating are 14% each.
- Hard numbers repay memorizing: 25 lbf, 4 times outside diameter, 13 mm untwist, 90 m and 100 m, 40% fill, 1.5 m support spacing.
- Build a whole-box habit for cable estimates: divide the box by the run, round down, then divide the outlets by whole pulls and round up.
