摘要： PURPOSE:To facilitate an easy the wiring work and others as well as to enhance the maintenance performance by trunk-connecting in series the auxiliary unit and the using unit groups and distributing the switching means to each using uint side. CONSTITUTION:Channel unit groups NW0-NWm are controlled by channel driving units SCO-SCn, and the channel driving units contain common auxiliary unit SBY. The signal line led from unit SBY is connected to unit SCO via cable CNO attached with the connector, and each channel unit mounted on frame SCF is all connected in series via cables CN1-CNn. Thus, the auxiliary unit is connected to the using unit. In case some fault takes place in the using unit, the switch relay relating to the faulty unit is actuated to switch the faulty unit to unit SBY. As a result, both the wiring work and the ectension work can be facilitated, thus enhancing the maintenance performance.

摘要： PURPOSE:To reduce the burden of a microcomputer considerably, by transmitting a synchronizing signal to the highway of a time division converter before transmitting a data signal and by not accessing a data processing device until receiving of data of one section is terminated. CONSTITUTION:When having data to be transmitted to a highway 10, a microcomputer 1 controls an interface adapter 2 to set 8-bit data. The adapter 2 generates a bit string where a synchronizing signal and a parity bit are added to this data. This pluse train is transmitted to the highway 10 through a multiplexer 3 for every time slot indicated by a control circuit 5. Meanwhile, a demultiplexer 4 extracts the pulse train on a highway 11 for every time slot designated by the control circuit 5; and after the synchronizing signal is detected by inversion of the normal state in the adapter 2, the parity check and the read of the data signal are performed.
