Quiz: DSL

DSL (Digital Subscriber Line) is a technology for bringing high-bandwidth information to homes and small businesses over ordinary copper telephone lines. Test your knowledge and find out if your brain cells are "always on".

1. This is the protocol used to "gather" DSL traffic from usersand forward it to a Digital Subscriber Line Access Multiplexer, which consolidates traffic across the backbone network.
a. forward DNS lookup
b. Transmission Control Protocol
c. Asynchronous Transfer Mode
d. Accelerated Hub Architecture

2. This form of DSL uses most of the channel to transmit downstream to the userand only a small part to receive information from the user.
a. VoIP
b. Asymmetric Digital Subscriber Line
c. ISDN
d. cable modem

3. This trademarked version of DSL that is somewhat slower than ADSL but has the advantage that a "splitter" does not need to be installed at the user's end.
a. Unified Messaging
b. Consumer DSL
c. G.Lite
d. Netcaster

4. This device divides the incoming signal into low frequencies to send to voice devices, and high frequencies for data to the computer.
a. multicast router
b. interface device
c. sequencer
d. splitter

5. This is a network device, usually at a telephone company centraloffice, that receives signals from multiple customer DSL connections and puts the signals on a high-speed backbone line.
a. MBone
b. repeater
c. hub
d. DSLAM

6. This is the leading method of signal modulation for DSL servicein which the usable frequency range is separated into 256 frequency bands(or channels) of 4.3125KHz each.
a. pulse code modulation
b. Discrete Multitone
c. frequency-division multiplexing
d. Signaling System 7

7. This is a technology from US Robotics (now 3Com) for the downstream transmission of data over ordinary phone lines at 56 Kbps.
a. Y-modem
b. xDSL
c. Z-modem
d. x2

8. This term is used to describe multiple signals or streams of information sent at the same time in the form of a single, complex signal and then recovered as separate signals at the receiving end.
a. multicast
b. multilink bundle
c. multiplexing
d. multithreading

9. This type of DSL is used for wideband digital transmission within a corporate site and between the telephone company and a customer.It is symmetrical, meaning that an equal amount of bandwidth is available in both directions.
a. BAL
b. high bit-rate DSL
c. vBNS
d. wideband code-division multiple access

10. This was the original approach for modulation of a Digital Subscriber Line (DSL) signal.
a. carrierless amplitude/phase
b. pulse code modulation
c. quadrature amplitude modulation
d. phase-shift keying
