<html><head></head><body>For a period of time, the University of Maryland had a MILNET connection via the IMP/PSN at the NSA. As I recall, it used ECU devices at each end to connect the LH/DH-11 1822 Interface in the VAX 11/780 to the 56k DDS line. <br>
<br>
I'm not sure what MILNET related research contract the CS department had which precipitated the MILNET connection, though I don't recall any PLI discussion. <br>
<br>
Later, UMD also had an APRANET PSN on site related to the NSFNET project to interconnect the those two networks. <br>
