Abstract

PURPOSE:To increase the processing ability of line concentrator for telephone exchanger, by directly enabling to access for the processor without registers, through the exclusive use of a part of memory area possible for access for the processor to the scanner (SCN) data storage memory. CONSTITUTION:One of data write-in and data readout to an SCN data storage memory 11 is made with a hardware logic, and one of others is made with software control in a control device, then an address bus 20 is directly connected to a selector 17 and the memory 11 is connected to a data bus 19. Further, the exclusive part of area of the memory 11 is accessed with the processor, and the data from the memory 11 is output to the data bus 19. Thus, the processing ability of interface among the signal distributor, scanner and processor, in a line concentrator for telephone exchanger is increased and the amount of hardware can be reduced.
