Which of the following terms defines a value that represents voice quality in a network depending on codec and
region? (Select the best answer.)
A.
Jitter
B.
QoS
C.
MOS
D.
R-Factor
Explanation:
Of the available choices, the term Mean Opinion Score (MOS) defines a value that represents voice quality in a
network depending on codec and region. MOSs are calculated scores that are mitigated by voice quality
hindrances, such as latency and jitter. In addition, MOS scales are not standard across codecs and regions.
Therefore, the MOS scale for one codec might not be applicable to another codec. Devices such as the Cisco
Network Analysis Module (NAM) monitor active Realtime Transport Protocol (RTP) streams in order to gather
the statistical data to compute the MOS.
An R-Factor is also a value that represents voice quality in a network. However, the way R-Factor
measurements are calculated is the same across all codecs and regions. Therefore, R-Factor measurements
might be a simpler means of evaluating an enterprise that spans regions or deploys a number of different
codecs.
Quality of Service (QoS) is a Voice over IP (VoIP) technique that ensures call quality and integrity by mitigating
delay and dropped packets, which can interrupt the flow of a VoIP call. Typical QoS techniques include buffer
management and the use of multiple transmission queues to separate types of multimedia packets. Because
voice traffic is sent in real time, quality is critical.
Jitter is a variation in delay that can cause packets to arrive out of sequence or at a different rate than they were
sent. As a result, the end user might experience choppiness in the audio connection. Thus shorter packet
roundtrip times contribute to better voice quality.https://www.cisco.com/c/en/us/products/collateral/interfaces-modules/branch-routers-series-network-analysismodule-nme-nam/white_paper_c11-520524.html
