Abstract

PURPOSE:To shorten the delay time of a telegram in a switchboard, by providing a shift register between an incoming line and a channel switch and by reading connection information preceding the telegram to control the channel switch and by transmitting the telegram to an outgoing line. CONSTITUTION:A header reading part 4 having a shift register 41 is provided between an incoming line 1 and a channel switch 3. Connection information (header) precedes each telegram; and when it is discriminated by the header reading part 4 that connection information has come to the shift register 41 completely, this coming is reported to a bus matching part 6, and connection information is transferred. The bus matching part 6 receives the incoming line number, the channel number, and connection information to determine an outgoing line 2 and selects an idle channel to control the channel switch 3. During the connection control, the telegram is held in the shift register 41. Thus, the delay time of the telegram in the switchboard is shortened, and the line efficiency is improved because the service path is formed only in the time of passage of the telegram.
