Free BICSI Installer 1 Exam Flashcards

TIA-568. It's the standard installers reach for pinouts and category ratings, separate from TIA-569 (pathways/spaces), TIA-606 (labeling), and TIA-607 (grounding/bonding).

TIA-606 (Administration). It standardizes labels, cable IDs, and records so any technician can trace a circuit later — a different concern from TIA-568's performance specs.

The site safety plan. Field Planning/Implementation/Design folds safety verification and supply-inventory checks into the same domain — there is no separate 'Safety' domain on the exam.

STP (shielded twisted pair) adds a foil or braid shield with a drain wire; that drain wire must be grounded at termination or the shield does nothing to reject EMI. UTP has no shield at all.

Cat 6A (500 MHz bandwidth). Cat 6 (250 MHz) only supports 10G reliably to about 37-55 m because of alien crosstalk, so it can't guarantee 10G over a full 100 m channel.

Blueprints show designed pathway routes, telecom space locations, and outlet placement — following them prevents pulling cable to the wrong location or missing a designed pathway.

A TR serves horizontal cabling cross-connects for a floor or work area; an ER centralizes more complex equipment (servers, PBX) and typically serves the whole building or multiple floors.

The Entrance Facility (EF). It's the demarcation point where external cabling enters the building, distinct from a TR or ER, which only handle internal distribution.

3 m x 3.4 m (about 10 ft x 11 ft). TIA-569 sets this minimum so the room can hold racks, cross-connects, and required clearance for the area it serves.

18-27°C (64-80°F). Because TRs often aren't prioritized like data centers for HVAC, installers should verify the building's cooling actually reaches this range before equipment is installed.

No. The minimum separation from fluorescent lighting is 5 in (127 mm); at 4 in the run is too close and risks induced noise from the ballast.

24 in (610 mm) — double the 12 in (305 mm) required for 2-5 kVA lines, and less than the 48 in (1.2 m) required near motors rated 5 kVA or higher.

53%. Fill percentage isn't linear with cable count — it drops to 31% for exactly 2 cables, then rises back to 40% for 3 or more cables.

A short nipple has minimal bend and pulling-friction risk, so code allows a higher fill percentage than the 31-53% limits that apply to longer conduit runs.

Four times the cable's outer diameter. Bending tighter deforms the internal twist geometry, degrading NEXT and return-loss performance even when the jacket shows no visible damage.

1.2-1.5 m (4-5 ft) apart. Proper spacing prevents sag, which creates sharp bend points and can pull cable outside its designed pathway.

A firestop system. It seals the opening around the cable; leaving the penetration unsealed after a pull is a code violation and creates a path for fire and smoke to spread.

The TGB (Telecommunications Grounding Busbar) is the local ground point inside each TR; the TBB (Telecommunications Bonding Backbone) is the conductor that connects every floor's TGB back to the building's main ground point (TIA-607).

It's a fire-rated fitting that lets cable pass through a floor slab from one level to the next while preserving the floor's fire rating — used for vertical runs outside a dedicated shaft.

Innerduct isolates and protects fiber optic cable from other cables sharing the same conduit or tray, and makes future adds/moves possible without disturbing the existing fiber.

CMP (plenum-rated) cable, supported on dedicated J-hooks or cable tray — never resting on or supported by the ceiling tiles themselves, which aren't rated to bear cable weight.

It must be re-sealed with firestop material. An open penetration left after pulling cable is a code violation until the fire/smoke rating is restored.

25 lbf (110 N). Exceeding this can stretch conductors and disturb the twist ratio inside the jacket, degrading transmission performance even though the cable looks undamaged.

It gives the installer a way to attach and pull the actual cable through later without having to fish an empty conduit — pulling the string is far easier than pulling cable blind.

On a reel stand so the spool rotates freely as cable feeds off — pulling from a reel that can't rotate twists and kinks the cable instead of paying it out cleanly.

From the center hand-hole of the box, which lets the cable pay out without added twist. Pulling from the outside of a coil instead introduces twist that can cause kinks.

About 3 m (10 ft) of slack lets the cable be re-terminated or relocated later without having to pull a whole new run — it's built-in margin for future changes.

Snug, never overtightened. Overtightening can deform the cable jacket and disturb the internal twist of the pairs at that point, creating a localized performance defect.

Top-down uses gravity to assist the pull and is preferred when access allows; bottom-up requires a winch or capstan to haul cable upward when top access isn't available.

No. Code allows a maximum of four 90° bends (360° total) between pull points — a fifth bend requires breaking the run with a pull box to keep pulling tension manageable.

Backbone cabling connects TRs, ERs, and the EF to each other (between floors or across a campus); horizontal cabling runs from a TR out to the individual work-area outlet.

Lubricant reduces friction against the conduit wall, lowering the tension needed to complete the pull — but it must be compatible with the cable jacket material or it can damage it.

It transfers pulling tension to the cable's strength member or outer jacket instead of directly to the conductors, protecting the conductors and connectors from pull-force damage.

The green pair (white-green/green). T568A is the US federal/USOC-aligned standard and the default for government installations.

The orange pair (white-orange/orange). T568B is the common commercial default, tracing back to the legacy AT&T wiring standard.

A crossover cable — historically used to connect two like devices (e.g., switch-to-switch) directly. A straight-through cable uses the same standard on both ends, which is the default for connecting a device to a switch or patch panel today.

A 66 block is a legacy voice-only design rated only to Category 3; a 110 block is a higher-frequency IDC design that supports both data and voice circuits at Cat 5e/6 performance.

An IDC cuts through the wire's insulation when seated, making the connection without stripping the conductor first — that's exactly what a punch-down tool is designed to do.

A punch-down tool seats IDC connections (110/66 blocks, jacks); a crimping tool attaches RJ-45 plugs onto the end of a patch cord. They terminate different types of connectors.

0.5 in (13 mm) maximum. Untwisting further than this to make the termination easier increases crosstalk and can cause the pair to fail NEXT testing.

F-type connectors are standard for residential/CATV coax; BNC connectors are used for professional video and some legacy data coax applications.

The wiremap test. It verifies pin-to-pin connectivity and correct pair mapping — but a basic wiremap tester can still show a 'pass' on a cable that has a split pair.

The channel includes the patch cords at both ends of the link, while the permanent link measurement covers only the fixed infrastructure with no patch cords.

NEXT (near-end crosstalk) measures signal coupling between pairs at the near end; return loss measures signal reflected back due to impedance mismatches, often caused by poor terminations.

A split pair. Continuity checks each pin individually and doesn't catch it, but pairing wires from two different pairs instead of a true twisted pair destroys the twist's crosstalk cancellation, so NEXT fails.

An open is a broken conductor path with no continuity; a short is two conductors touching each other that shouldn't be connected. Both are basic wiremap-detectable faults, unlike a split pair.

A reversed pair swaps the transmit and receive conductors within the same pair position; a crossed pair puts an entire pair in the wrong pin position relative to the standard. Both are wiremap-detectable, unlike a split pair.

NEC 800.25 requires abandoned cable to be removed, not just disconnected, because unused, unrated jacket material left in a plenum space adds fire load and smoke-generation risk.

Paging, sound masking, and nurse call are typical examples, along with building automation (BAS), life-safety/fire-alarm integration, and elevator controls — all riding on the same converged ICT cabling infrastructure instead of separate proprietary wiring.

Article 770 (optical fiber), Article 725 (Class 1/2/3 circuits), and Article 820 (CATV and coax systems) — each governs a different cabling type separately from Article 800's general communications scope.
