The application discloses a remote digital signal wire distribution system. The remote digital signal wire distribution system comprises a remote control terminal and wire distribution devices, wherein the wire distribution devices are arranged at node stations in a digital signal wire network; each wire distribution device comprises an acquisition unit, a wire distribution communication unit and a wire distribution unit. Resource data of each node station is acquired through the corresponding wire distribution device and sent to the remote control terminal which is arranged at a central station, the remote control terminal judges whether data transmission between two node stations fails or not according to the acquired resource data and generates a corresponding switching instruction and feeds back the instruction to the corresponding wire distribution device if the data transmission between two node stations fails, and a failed digital signal wire is switched into a failure-free digital signal wire through the wire distribution device, so that the data transmission failure in the digital signal wire network can be remotely and automatically corrected, an operator does not need to perform operation such as failure positioning and manual jumping in each node station, the probability of misoperation is reduced, the failure maintenance time is greatly shortened, and the communication maintenance efficiency is improved.
