That pin was commonly used with a DEC current loop converter module, the
number of which I forget (DLV11-K ???). That box plugged into the DLV11-J
at one side and had an 8 pin Mate-n-lock on the other to connect to a
standard DEC current loop cable. It also included a 110 baud (1760Hz)
generator, since the DLV11 couldn't do 110 baud as standard and the most
common reason for wanting a current loop interface was to connect to an
ASR33.
