What technology is characterized by high-capacity telecommunications signal transmission?

Asynchronous Transfer Mode (ATM) is characterized by high-capacity telecommunications signal transmission due to its ability to transfer data in fixed-size packets called "cells." This technology is specifically designed for speed and efficiency in transferring various types of data, including voice, video, and internet traffic. Each cell is 53 bytes long, which enables ATM to maintain effective transmission speeds and lower latency.

ATM is particularly beneficial in environments that require a large amount of data to be transmitted quickly and reliably, such as broadband networks and high-performance computing environments. Its ability to handle simultaneous data streams with Quality of Service (QoS) guarantees makes it suitable for applications where timing and bandwidth are critical, such as video conferencing and online gaming.

Other options also involve data transmission but are not primarily designed for high-capacity telecommunications. For example, Digital Subscriber Line is primarily focused on delivering internet access over phone lines but does not achieve the same high capacity and versatility as ATM. Frame Relay, while a packet-switching technology, operates with variable packet sizes and is not as effective for high-capacity needs as ATM. Voice over Internet Protocol, on the other hand, is primarily concerned with transmitting voice data over the internet and may not support the same level of transmission capacity as ATM does for
