Abstract

PURPOSE:To reduce the trun-around time at calling and to achieve efficient connecting means, by providing a circuit which selects the control information transmitted to the device at the next stage with channel state in the line concentrator group of itself with the line concentrator. CONSTITUTION:When line concentrator group for all the concentrator is busy, the line concentrators of CST1-CSTn-1 transmits the connection request after reception to the concentrator at the next stage as it is, and busy response is produced at a CSTn and returns it to the calling terminal. Further, when a channel in the line concentrator group of at least one line concentrator is not busy, all the line concentrators (all busy) at higher rank than this line concentrator CSTl of the uppermost rank transmits the connecting request received the same as mentioned above as it is to the next stage, the said CSTl produces the connection enable response and returns it to the calling terminal.
