A) synchronous
B) statistical
C) empirical
D) random

Question

Quizplus · Accepted Answer

SONET and SDH are both synchronous multiplexing techniques, meaning that they use time-division multiplexing to transmit multiple signals simultaneously over a single physical link with synchronized timing. This allows for efficient use of bandwidth and reliable transmission of data. Statistical multiplexing, on the other hand, is a technique used in packet-switched networks where bandwidth is dynamically allocated based on traffic patterns. Empirical and random multiplexing techniques are not commonly used in telecommunications.
