Abstract
In the exchange system where line terminator is connceted individually at the input-output line, this system provides the multi-address determining and conference communication connection, and has a device which is scanning the line terminator and determining the address of connection memory, thus the valve in the storage cell of the determined address of the conncetion memory is known and each time line terminators are connected together only for the purpose of transferring the message. Another purpose of this system is that terminations already employed in exchange systems will be used in common.
