FeTAp (Fernsprechtischapparat) 751
The FeTAp 7-series was announced on the 15th of november 1976 by the Deutsche Bundespost and was available to subribers from 1977.
It was the first telephone for the Deutsche Post that was specifically designed for a key pad.
The telephone itself was designed by Siemens, the key pad was designed by Hagenuk.
There was a pulse version, the 71x, a Dioden-Erd-Verfahren version, the 73x, and a DTMF version like mine, the 75x.
As the demand for common rotary dials remained with German subscribers, a rotary dial version was introduced in the late 1970’s: the FeTAp 791.
