Digital data can also be represented by (71)signals by use ofa modem. The modem converts a series of binary voltage (72) into an analog signal by encoding the digital data ontoa carrier frequency. The resulting signal occupies a certam spectrum of (73) centered about the carTier and may be propagated acrossa medium suitable for that carrier. The most common modems represent digital data in the voice(74)and hence allow those datato be propagated over ordinary voice-grade (75 )lines At the other end of the line, another modem demodulates the signal to recover the original data(71)A.analogB.digitalC.ModemD.electric
Which three statements are true about the data traffic characteristics of voice traffic？ （）A、latency must be kept below 150 msB、latency is not a concern as long as jitter is kept below 30 msC、voice packets do not require a specific type of queuingD、voice packets are rather smallE、voice packets require TCP for rapid retransmission of dropped packetsF、voice packets require a fairly constant bandwidth reserved for voice control traffic as well as forthe voice payload
Which two statements are true about voice packets in a LAN？ （Choose two.） （）A、 Voice traffic data flow involves large volumes of large packets.B、 Because a packet loss involves a small amount of data， voice traffic is less affected by packet losses than traditional data traffic is.C、 Voice carrier stream utilizes Real-Time Transport Protocol （RTP） to carry the audio/media portion of VoIP communication.D、 Voice packets are very sensitive to delay and jitter.E、 Voice packets are encapsulated in TCP segments to allow for proper sequencing during delivery.
Which two statements are correct about the signaling methods that are utilized for transmitting voice？ （）A、 Channel-associated signaling transmits control signals in band and therefore reduces the bandwidth available for the voice data stream.B、 Channel-associated signaling utilizes a separate TDM channel for transmitting control signals.C、 Common channel signaling transmits control signals in band and therefore reduces the bandwidth available for the voice data stream.D、 Common channel signaling uses one of the TDM channels to transmit control information reducing the number of channels available for voice.E、 ISDN BRIs implement channel-associated signaling.
