Glossary

and data applications requiring a carrier frequency of

up to 100 MHz. Now the most common cabling being

installed for LAN connectivity. Defined by FCC Part 68,

EIA/TIA-568, TIA TSB-36 and TIA TSB-40.

Category 5e (Enhanced) CAT5e A Category of

Performance for inside wire and cable. Used in sup-

port of signaling rates of up to 100MHz over distances

of up to 100 meters. Calls for tighter twists, electrical

balancing between pairs and fewer cable anomalies.

CAT5e is intended to support 100Base-T, ATM and

Gigabit Ethernet.

Category 6 CAT6 A developing cable standard for

UTP (Unshielded Twisted Pair) intended to support sig-

naling rates up to 200 MHz. Applications will include

100Base-T, ATM and Gigabit Ethernet and wiring under

development.

CATV Community Antenna Television. A broadband

system that transmits signals from a central antenna

throughout a community via coaxial cable

CCTV Closed circuit television in which the broadcast

is sent to a limited number of locations, such as in a

security system.

Channel The end-to-end transmission path between

two points at which application-specific equipment is

connected in a data system. A tunable frequency car-

rying audio and/or video signals on a modulated carri-

er.

Coaxial Cable A cable composed of an insulated

central conducting wire wrapped in another cylindrical

conductor (the shield). The whole thing is usually

wrapped in another insulating layer and an outer pro-

tective layer. A coaxial cable has great capacity to

carry vast quantities of information. It is typically used

in high-speed data and CATV applications.

Compliance A wiring device that meets all character-

istics of a standard is said to be in compliance with that

standard.

Conductor Any substance, usually a wire or cable,

that can carry an electrical current.

Connecting Block Also called a terminal block,

punch-down block, quick-connect block, or crosscon-

nect block. A plastic block containing metal wiring ter-

minals to establish connections from one group of wires

to another. Usually each wire can be connected to sev-

eral other wires in a bus or common arrangement. There

are several types of connecting blocks: 66 clip, BIX,

Krone, 110, etc. A connecting block has insulation dis-

placement connections (IDCs), which means you don’t

have to remove insulation from around the wire conduc-

tor before you “punch it down” (terminate it).

Connector A device that connects wires or fibers in

cable to equipment or other wires or fibers. Wire and

optical connectors most often join transmission media

to equipment or cross connects. A connector at the

end of a telephone cable or wire is used to join that

cable to another cable with a mating connector or to

some other telecommunications device.

Crossconnect Distribution system equipment used to

terminate and administer communication circuits. In a

wire crossconnect, jumper wires or patch cords are

used to make circuit connections. In an optical cross-

connect, fiber patch cords are used. The crossconnect

is located in an equipment room, riser closet, or satel-

lite closet.

Crosstalk See Near-End Crosstalk.

Daisy Chain In telecommunications, a wiring method

where each telephone jack in a building is wired in

series from the previous jack. Daisy chain is NOT the

preferred wiring method, since a break in the wiring

would disable all jacks “downstream” from the break.
