FIELD: means of communication. ^ SUBSTANCE: invention refers to electric communication and can be used for railway transport. It is achieved by the fact that digital communication system of railway transport of each railway station includes primary multiplexers connected with the primary synchronous digital hierarchy channel; at that, they include digital adders and distributors; at that, in the primary multiplexer of one of the stations of the section, controlled keys are switched on in series with adders. Primary multiplexers at terminal stations are connected through the first in-series connected adapter units, the first commutators and the first routers to the primary circuit which is connected in the common control centre to the second router, the second commutator and the third router; at that, one of the outputs of the second commutator is connected to communication channel of the common monitoring and managing system, and the output of the third router is connected to IP LAN server and to dispatching communication control panels. At each station primary multiplexes are connected through the second in-series connected adapter units, the third commutators, the fourth routers to IP station networks to which there connected are communication and remote control devices; at that, each IP station network is equipped with the proxy server connected to the third commutator output. ^ EFFECT: enlarging functional capabilities of communication system. ^ 1 dwg |
