INVENTION: APPARATUS WORKING WITH PULSE-CODE-MODULATION OR SIMILAR DIGITIZING TECHNIQUES AND ACCORDING TO TIME-DIVISION MULTIPLEXING PRINCIPLES FOR PROCESSING INFORMATION FROM A NUMBER OF TELEPHONE CHANNELS ABSTRACT OF THE DISCLOSURE An apparatus working with pulse-code-modulation or similar digitizing techniques and according to the time-division multiplexing principle for processing the information from a number of telephone channels, comprising a housing at the front plate of which there are arranged operating elements and possessing terminals for the input of the information to be processed and the output of the processed information. Accommodated in the housing, apart from the components commonly associated with all of the telephone channels, is a group of components for each telephone channel which possesses, apart from the components needed for the conversion of the analogue signals into digital pulses and for the digital pulses into analogue signals, also call signal converters and call signal transmitters, respectively. The group of components of each channel is adjus- table by means of an associated operating or actuation element arranged at the housing-front plate independent of the components of the remaining channels to one of a number of operating states, and for at least one of these operating states the arriving digital pulses pass without change through the related channel.
