Abstract
PURPOSE:To make the titled terminator applicable also to the ISDN conversion system by connecting a line reaching an analog telephone adaptor section to a signal multiplex/demultiplex circuit in mounting the analog telephone adaptor section and connecting a line reaching directly the ISDN line adaptor section to the signal multiplex/demultiplex circuit in mounting the ISDN line adaptor section. CONSTITUTION:In mounting analog telephone adaptor sections 211, 221, the line reaching the analog telephone adaptor sections 211, 221 via call processing signal conversion circuits 91, 92 and the line reaching directly the ISDN line adaptor section 2m1 not through the call processing signal conversion circuits 91, 92 is connected to the signal multiplex/demultiplex circuits 121, 122 in mounting the ISDN line adaptor section 2m1 by means of changeover switches 1311, 1321. Thus, the analog telephone set is accommodated to the exchange system controlled by the signal system specified by the ISDN via a 2-wire subscriber line and also the subscriber terminator accommodating both the analog subscriber terminal equipment and the ISDN subscriber's equipment is realized.
