Abstract

PURPOSE:To make it possible for a switchboard to attain communication with a terminal at a signal rate by detecting the transmission rate of data from the terminal in the switchboard equipped with a transmission control circuit that provides digital transmission and reception of signals from the terminal. CONSTITUTION:Switchboard 10 is equipped with sending circuits 101...104, which are connected to terminals 1...4 via connectors 111...113. For example, when the electric power source of terminal 3 is put into operation and a data signal of at least one bit is sent to circuit 103, rate detecting circuit 101 detects its data rate and clock generating circuit 102 generates data of the same rate as the transmission rate of the reception. Then, controller 107 uses data buffers 103...106 to perform the transition of clocks between terminal 3 and common buses 121 and 122. Consequently, communication with the terminal can be carried out by the switchboard at the signal rate from a random terminal.
