Abstract
In a digital signal transmission system for effecting time-division multiplexing/circuit switching transmission of data in the form of packets by means of telecommunication cable, a packet configuration and line connection control data inserted in the packets are improved. In phases of the establishment/termination of a call, line connection control data of the overhead field are inserted as repeated at least one time into the data field. At least one set of line connection control data of the overhead field contains a parity bit. A receiving station reads the line connection control data in the overhead field and the data field of a received packet, and determines the overhead data by the principle of decision by majority. After completion of establishment of a call, the receiving station takes in the transferred data out of a block on the basis of a positional information, for example, a number of the block. In the phase of transmission of data, transmitting station inserts additional data bits into at least part of the overhead field in the packet being transmitted.
