Exam Test Questions And Answers
Verified 100% Correct
Satellite/Voting Receiver Systems - ANSWER -Satellite receivers are placed
strategically throughout the required coverage area. They receive the signal from a
portable or mobile within close proximity and send the signal, via microwave or
landline, to a central controller.
Digital v. Analog - ANSWER -Analog uses the voice's vibration to send the voice
to the transmitter.
Digital converts voice to a sequence of 1 and 0, transmits it, and then converts it
back to sound.
Data Signaling - ANSWER -Data sent via radio, which includes alerts to indicate
an emergency, fingerprints, images, and maps. Data signalling is an integral part of
trunked P25 radio systems.
Location-Determination Technology - ANSWER -Two categories: handset-based
and network-based. Handset-based location technologies incorporate GPS
technologies and network-based technologies use triangulation.
Global Positioning System (GPS) - ANSWER -Developed by the US Department
of Defense the system uses 24 satellites orbiting 12,600 miles above the earth.
With the measurement from a minimum of four different satellites, the lat, long,
altitude, course, and speed can be calculated.
Differential Global Positioning System (DGPS) - ANSWER -Relies on a
calculation from a second terrestrial receiver at a known fixed location to the
satellite and then compares it to the first calculation.
Assisted Global Positioning System (AGPS) - ANSWER -Is the handset-based
location determination method used in wireless networks to acquire the location of
a 9-1-1 caller.
Uplink Time Difference of Arrival (U-TDOA) - ANSWER -Predominant
network-based location technology used for wireless 9-1-1 calls. Works by
,determining the location based on the time it takes a signal to travel from a mobile
phone to each of the sensitive receivers called location measurement units (LMUs).
Does not require special hardware or software. Does not work well in areas with
sparse cell site spacing.
Telecommunications Service Providers - ANSWER -Carry information through a
network in the most efficient way possible, using no more resources that are
necessary.
InterLATA and Interexchange - ANSWER -A Local Access and Transport Area
(LATA) is a specific geographic area within which a local TSP may offer either
local or long distance service.
Local Exchange - ANSWER -Refers to the service area provided by an end office.
Local Loop - ANSWER -Refers to the wires that run fro the subscriber's PBX,
telephone, or key telephone system back to the serving central office.
Legacy Telephony Switching - ANSWER -Switching is the process of connecting
the calling party to the called party without the use of dedicated transport facilities.
The basic function of a switching network is to provide communications paths
from the calling party to the called party.
Central Office - ANSWER -Refers to a local switching system that connects lines
and trunks and sometimes refers to a TSP building in witch switching system and
telephone equipment are installed.
End Office of Class 5 Office - ANSWER -A switching system within a Local
Access and Transport Area (LATA) where customer lines are terminated for
purposes of interconnection to each other and to trunks.
Access Tandem - ANSWER -The access tandem provides the interexchange
carrier with access to all the end offices within the LATA.
Facility of Facilities - ANSWER -Can apply to any one of the elements of
physical telephone plant that is required to provide service. Facilities can include
switching systems, cables, microwaves, buildings and/or factories.
VoIP Services - ANSWER -Involves sending voice information in a digital form
in discrete packets rather than by using the traditional legacy circuit switched
, protocols of the PSTN. Call serves route the packets containing voice. Users do not
need a traditional telephone number, but may have a unique Uniform Resource
Identifier (URI) that allows one VSP customer to call another.
Commercial Mobile Radio Services (CMRS) - ANSWER -Also known as a
wireless service provided (WSP), is an FCC term for any carrier or licensee whose
wireless network is connected to the PSTN.
Code Division Multiple Access (CDMA) - ANSWER -Spreads data over the
entire available bandwidth, sent in small pieces over a number of discrete
frequencies.
Transport Facilities - ANSWER -Refer to the physical medium over which
transmission takes place. Types of media include copper wire, fiber optics,
microwave, satellite, and coaxial.
Copper Wire - ANSWER -Typically composed of twisted pairs, which is two
insulated copper wires twisted around each other to reduce induction.
Fiber Optics - ANSWER -A technology in which light is transmitted through thin
filaments of glass, the light is turned off billions of times per second to represent
binary signals - analog signals cannot be used on fiber.
Microwave - ANSWER -Provides a way to transmit telephone, fax, video, and
data conversations using electromagnetic waves in the radio frequency spectrum
above 8990 Megahertz and below 20 Gigahertz. Microwaves are very directional,
they travel in straight lines for up to 30 miles.
Coaxial Cable - ANSWER -Developed to provide a more effective way to shield
wires from outside electrical interference.
Stand-Alone Switch - ANSWER -Designed to serve a geographic area where the
subscribers are within the defined loop length.
Host/Remote Switch - ANSWER -Allows a host switching system to be located in
a central location and remote switching units to be distributed throughout the
serving area closer to the customers.
Access Tandems - ANSWER -Used to interconnect end offices when direct
trunking is not economically justified or when alternate routing is justified.
