Standards work comes with a language of its own. This glossary collects the abbreviations you’ll come across throughout the DTS Toolkit, the bodies that write the standards, and the telecoms, security, web and EU regulatory terms that sit alongside them, so you can look up anything unfamiliar without breaking your stride.
