- gpvos 9y agoIn 1965 there wasn't much international direct dialling yet; mainly to neighbouring countries. The rest was done via an operator. International exchanges tended to buffer the entire called phone number anyway, even back in electromechanical times, which meant they could also translate the pulses if that would have been necessary.
