Abstract
PURPOSE:To miniaturize and economize a concentrator and to simplify an exchange software with the standardization of a control system by arranging the signal processing device of an ISDN basic subscriber line behind a main switch and controlling the remote and office concentrators from a concentration signal processing device. CONSTITUTION:A concentration signal processing device 23 and a D channel signal processing device 24 are arranged behind a main switch 22 of an exchange, a D channel is set between a user terminal side and the D channel signal processing device 24 through a concentrator 23 and the main switch 22, and the remote concentrator and office concentrator 21 are controlled from the concentration signal processing device 23 by an instruction from the D channel signal processing device 24. Thus, a dropper-inserter and layer processing device are not required and the device can be miniaturized and economized. Since both of the remote concentrator and the office concentrator set concentration switches 20-1 and 21-1 by a control from the concentration signal processing device 23, the same standardized control can be executed as a remote and office concentrating system and the software in the exchanger can be simplified.
