The 20 mA current interface was the standard current loop interface for Teletypes such as the ASR-33 sometimes used as consoles for DEC minis.

I used them for a number of years on a couple of pdp8/m systems that had ASR-33s as consoles, and also took care of many 20 mA loops used with other Teletype models when I worked as an Associated Press technician in the early 1980s. AP used Lenkurt data sets to receive data from analog telco loops and convert it to current loops for teletypes.
