ATT ad in WSJ

ATT has an ad in today's (June 10, 1993) Wall Street Journal for their secure phone for $1200; they do not say how it works (neither cryptography nor Clipper are mentioned). Strangely, they suggest that it could be used in places where one could easily be overheard (like an airport--I don't know how they would connect to a public phone). Paul E. Baclace peb@procase.com
