Abstract

PURPOSE:To prevent the lowering in the ability of reconstitution of a line path due to a failure in a central station and to assure the performance of extent of a communication network, by using a line control system of scattering control type. CONSTITUTION:A line failure is detected at a failure detecting device 13 at the production of the failure and the identifying code of the line N produced with the failure is reported to a logical operating device 14. Further, the device 14 gives instruction to a storage device 15 to store failed lines and transmission lines not in use connected to the terminal station are judged from the content of storage of the storage device 15, a failure informing signal of the line demand N is transmitted to the nonuse transmission line and a transmission and receiving device 11 is controlled so that the reception of the said signal can be ignored. When the device 11 of the station P receives a failure informing signal on the line N from a transmission line PT, this is stored in the storage device 15 and a failure informing signal is transmitted to all the nonuse transmission line except the said PT. Thus, the nonuse transmission line detouring the mark X(failed point) is decided.
