The subscriber receiving apparatuses 100 to 115 convert the analog signal input through an external subscriber preference matching circuit into a digital signal, filter it, and deliver the filtering to the subscriber receiving matching apparatuses 116 to 119. 256 subscribers are connected to the subscriber receiving apparatuses 100 to 115, respectively, and four subscriber receiving apparatuses 100 to 103 are connected to one subscriber receiving matching apparatus 116. That is, eight sub-highways are connected as a physical connection between the subscriber-receiving matching devices per subscriber-receiving device 100, and one sub-highway can accommodate 32 subscriber telephone channels.

Subscriber acceptance matching devices 116 to 119 input test data provided from the test circuit built-in device 120 and transfer it to the subscriber accommodation device by a control signal input from a time division switch processor, and from the subscriber accommodation device. An interface device for receiving the provided data and delivering the data to the test circuit embedded apparatus 120 by a control signal input from a time division switch processor.
