<p>The call-number/terminal-number converter, for a PBX telephone system, has a second input multiple system and there is a second wiring system which is used for the reverse conversion of a terminal number into a call number. The second wiring system is associated with the terminal number being converted. The input multiple system and the second wiring system control a gate arrangement which causes the coding of the first wiring system together with a second output multiple system. The advantages lies in reducing the number of components needed for conversion.</p> |
