BROADBAND DIGITAL
INSTALLER TEST
A modular plug contains four-, six-, or eight-pin positions. Each
position is numbered and is used to terminate a specific tip or ring
wire from a quad or twisted-pair cable. How are the pins on a modular
jack numbered? - ANSWERS-From left to right, with the locking tab
down.
If a residence contains many modular jacks, a distribution device may
be used in addition to the network interface device (NID). What
components are contained in a distribution device? - ANSWERS-Tip
and ring screw or punch-down terminals, which are used to connect
the inside wiring.
Topology refers to the arrangement used in routing and connecting
inside wiring to the network interface device (NID) or distribution
device. How is the star topology arranged? - ANSWERS-A separate
twisted-pair cable is routed to each modular jack from the NID.
How does the insulation displacement connector modular telephone
jack differ from the screw-down post modular telephone jack? -
ANSWERS-The wires are connected using IDC termination slots,
which hold the twisted-pair wires.
In accordance with requirements set by the National Electrical Code
(NEC), several different cable types can be used for residential inside
,wiring. What is a CMR cable? - ANSWERS-A riser-rate unshielded
twisted-pair cable.
Which catergory of cable is best suited for datacenter and server-to-
switch links? - ANSWERS-CAT-8
Which wiring configuration is only used for voice systems and should
never be used when wiring modular data plugs or jacks? -
ANSWERS-Universal Service Order Codes (USOC)
Which of the following topologies starts at the network interface
device (NID) and routes through the customer premises from one
modular jack to the next? - ANSWERS-Bus topology.
In a home that has an addition, what type of wiring topology is it most
likely going to require? - ANSWERS-Hybrid topology.
What is the first step in prequalifying (i.e., inspecting and evaluating)
a new customer's existing telephony service? - ANSWERS-Locate all
active telephones and jacks.
What is the first step in prequalifying (i.e., inspecting and evaluating)
a new customer's existing broadband cable service? - ANSWERS-
Determine whether the customer has cable video service.
Which type of twisted-pair inside-wiring installation tool helps bend
and wrap the tip and ring conductors of the twisted-pair, inside-
, telephone wiring around the tip and ring binding posts on a network
interface device (NID)? - ANSWERS-Long-nose pliers.
Which wiring topology starts at the telephone distribution device,
uses one twisted-pair cable to route through a customer premises from
one modular jack to the next, uses a separate twisted-pair cable to
route a modular jack from another modular jack, and terminates at the
last modular jack location? - ANSWERS-Hybrid
When routing and attaching interior unshielded twisted-pair (UTP)
cable, what is the minimum separation distance you should maintain
between any telecommunications or data cable and electrical power
conductors? - ANSWERS-2 in.
When installing a modular telephone jack by mounting and wiring the
jack using a screw-down post at the customer premises, how much
insulation should be stripped from each individual copper conductor
with a wire stripper? - ANSWERS-1/2-inch to 3/4-inch.
After mounting and wiring a new modular telephone jack in a star
installation, where should the unshielded twisted-pair (UTP) cable
from the new modular jack be connected? - ANSWERS-To the tip and
ring screw terminals or insulation displacement connection (IDC) on
the telephone distribution device.
What is one operation to check after adding a new modular telephone
jack? - ANSWERS-Inbound call capability.
