E76 - Spritzwasserdichte Telefonstation LB, 1991

Visit http://fieldphones.org/episode76/ for additional information. This railway linemen telephone was made by "Ascom" (Fusion of former Swiss Telecom equipment manufacturers Autophon, Hasler and Zellweger) in the early nineties and used for a short time (before being soon replaced by GSM phones) on SBB and probably also other Swiss railway systems. It is very heavy duty, weather protected and I assume has been mainly used in combination with construction work along lines. The same devices seems to have been used also for fix installed telephones along some railway lines. Unique features Can use an external ring signal generator (90v~). (On my particular model call button to activate is present but external connectors not, most probably this option was used only on fixed installed telephones). 6V local battery to support active dynamic microphone capsules.
