Networking Infrastructure: Structured Cabling System

Vocabulary practice flashcards covering the key components, standards, and subsystems of TIA/EIA structured cabling systems.

Telecommunications Industry Association (TIA)

A trade association that jointly develops and publishes standards with the EIA covering structured voice and data wiring for local area networks (LANs).

Electronic Industries Alliance (EIA)

A trade association that collaborates with the TIA to develop and publish standardized specifications for structured voice and data cabling in LAN environments.

Structured Cabling System

The standardized installation of cabling infrastructure in a building or campus, organized into distinct subsystems to support voice and data communications.

Entrance Facility (Demarc)

The space containing the demarcation point where outdoor telecommunications provider cabling terminates and interfaces with the customer's on-premises backbone cabling.

Demarcation Point

The physical and operational boundary dividing the telecommunications service provider's network and responsibility from the customer's internal on-premises wiring.

Equipment Room (ER)

A centralized, building- or campus-serving room that houses sophisticated telecommunication and networking equipment such as servers, switches, routers, and main patch panels.

Telecommunication Room (TR)

A floor-serving facility housing patch panels and networking equipment (such as switches) that provides a transition connection between backbone cabling and horizontal cabling.

Backbone Cabling (Vertical Cabling)

Cabling, typically consisting of fiber optic cables, that interconnects equipment rooms and telecommunication rooms across different floors (risers), within the same floor, or between buildings.

Horizontal Cabling

Cabling, typically UTP, that extends from the telecommunication room patch panel to individual work area outlets through conduits, wireways, or ceiling spaces, with a maximum length of $90\,\text{m}$.

Work Area

A space serviced by an individual telecommunication room—usually occupying an entire floor or part of a floor—where end-user equipment connects to horizontal cabling outlets.

Patch Panel

A hardware unit mounted in a rack or cabinet containing ports used to connect and route circuits between backbone cabling, horizontal cabling, and active network switches.

Wiring Closet

A dedicated rack, cabinet, or small room within a facility used to house, mount, and organize patch panels, switches, routers, and cable terminations.

Faceplate

A wall-mounted plate installed at a work area to hold modular RJ-45 jacks, often populated with extra ports to accommodate future network expansion.

Consolidation Point

An intermediate horizontal cabling interconnection point situated between a telecommunication room's horizontal cross-connect and modular work area outlets in an open-office environment.

UTP Patch Cord

A flexible unshielded twisted-pair cable terminated with RJ-45 plugs, commonly limited to $5\,\text{m}$ in length, used to link devices to wall outlets or cross-connect patch panels.

RJ-45 Socket

An 8-position modular jack mounted in wall faceplates or patch panels that accepts an RJ-45 plug to connect work area devices to horizontal cabling.
