The digital recording system is an important device for accident checking, recall and analysis. At present, the common situation of digital recording system in rail transportation has some problems such as incomplete recording information or high cost. Based on the analysis of the dedicated telephone system composition and the status quo of centralized recording solution, this paper proposes the centralized recording solution for dedicated telephone system, introduces the system principle and features of centralized recording system and proves that the centralized recording can satisfy the requirements of the key terminal recording in dedicated telephone system.
