During the early 90s I worked at Cylink, a Crypto AG competitor. We too received a NSA visit about weakening products sold to certain clients (e.g., so-called narco-terrorists). I and the other directors were told of this (because we had legal responsibilities and liabilities) at a meeting. I assume we made the changes requested (e.g., weakening the RNG to NSA specifications). The special units were sold through a selected distributor in Louisiana (probably also a NSA contractor).
