[comp.dcom.telecom] Public Coin Operated TTD Phone

GREEN@wharton.upenn.edu (Scott D. Green) (03/01/90)

Sacramento, CA's airport provides a public TTD phone, consisting of a standard
armored pay phone and a secured TTD device.  Apparently, one places the call
normally and then couples, acoustically.  I do not know how the various 
"operator" messages are handled.
