Overview Edit

The NSA/CSS Secure Telephone System (NSTS) is

a stand-alone secure telephone system that allows conversation up to the TS-SCI level. IC entities call these phones by different names, such as grey, white, or green phones, although these colors do not always reflect the actual color of the telephone unit.[1]
