This standard specifies the two-level data communication between and within the basic operating units on passenger trains and its selection principles.
This standard is based on two communication networks: Types T and L networks. One of them shall be selected to form the user's train communication network based on train composition mode and the urgency of communication time limit.
This standard is applicable to variable composition trains and fixed composition trains on the railway.
