BICSI - TDMM - Part 1 - Terminology
Amplitude - correct answer-The maximum absolute value reached by a voltage or
current waveform. TDMM: Page G-9
Amplitude Modulation (AM) - correct answer-The modulation in which the amplitude
of a carrier wave is varied in accordance with some characteristic of the modulating
signal. TDMM: Page G-9
Analog Signal - correct answer-A signal in the form of a wave that uses continuous
variations of a physical characteristic over time (e.g., voltage amplitude, frequency)
to transmit information. TDMM: Page G-9
Attenuation - correct answer-The ratio in decibels of the output power (or voltage) to
the input power (or voltage) when the load and source impedance are matched to
the characteristic impedance of the cable. TDMM: Page 1-53
ATM - correct answer-Asynchronous Transfer Mode a high-speed packet switching
protocol that uses fixed-length (53-byte) packets organized into cells to carry all
types of traffic (e.g., voice, data, still image, audio/video). Fixed-length cells sallow
cell processing to occur in the hardware, thereby reducing transit delays. ATM is
designed to take advantage of high-speed transmission media, such as E3,
synchronous optical network (SONET), and T3.
AWG - correct answer-American Wire Gauge a system used to specify wire size.
The greater the wire diameter, the smaller the AWG value. TDMM: Page G-8
Bandwidth - correct answer-A range of frequencies available for signaling expressed
in hertz(Hz). It is used to denote the potential information handling capacity of the
medium, device, or system. TDMM: Page G-18
Broadband Cable - correct answer-Composite baseband video and audio signals
that are amplitude and frequency modulated, respectively, with an RF carrier in
accordance with the video and audio information that need to be conveyed. (e.g.,
CATV) TDMM: Page 1-47
CO - correct answer-Central Office a common carrier switching center office (also
called public exchange) that is conveniently located in areas to serve subscriber
homes and businesses. It provides telephony services(lines) that are connect on a
local loop. The CO contains switch equipment that can switch calls locally or to
long-distance carrier telephone offices. TDMM: Page G-34
Amplitude - correct answer-The maximum absolute value reached by a voltage or
current waveform. TDMM: Page G-9
Amplitude Modulation (AM) - correct answer-The modulation in which the amplitude
of a carrier wave is varied in accordance with some characteristic of the modulating
signal. TDMM: Page G-9
