DSx refers to which of the following?

DSx describes a family of standard digital transmission rates in telecommunications, built from the base channel DS0. DS0 is the 64 kbps voice channel, and higher DS levels stack multiple DS0 channels to form faster data rates—DS1 combines 24 DS0 channels to reach 1.544 Mbps, DS3 stacks multiple DS1s to much higher speeds, and so on. This framing of discreet, predefined levels is exactly what the term DSx refers to. The other options don’t fit because they pertain to unrelated concepts: digital signature frameworks involve cryptography, a medical imaging color space standard concerns how colors are represented in images, and telemedicine reimbursement codes deal with billing and coding for services. DSx is specifically about the predefined ladder of digital transmission rates in the telecom hierarchy.
