PURPOSE:To store an arbitrary line corresponding part in the corresponding common part of the same line by storing data for a type in the corresponding part to the line in a digital exchanger, and extracting and storing the data for the type in the common part corresponding to the line at the time of the initialization. CONSTITUTION:A signal commonly control circuit 18' in the common part 12' corresponding to the line extracts the data CD for the type stored in a register 36 or the like in the corresponding part 7' to respective subscriber line mounted on the same circuit shelf 9' and stores in a writing and reading memory 39. Thereafter, after the data CD for the type and service information SV are referred, the form of a signal is transformed and transformed into an unified form suitable for a highway 24. Therefore, on the same circuit shelf 9', the corresponding part 7' to the subscriber line, an analog repeating line corresponding part 8' to or a digital terminal 6' can be mounted. Accordingly, according to the type of the respective stored lines, it is not necessary to provide an exclusive common part corresponding to the line, the flexibility is present in the increase of the corresponding parts to the lines together with the increase in the lines or the like and a compact and economical characteristic is promoted.
