In article various application fields of switching systems, and switching modes, characteristic for them are considered. The output that packet the switching mode is general-purpose is drawn, allowing to implement methods of parallel switching in some space switches. For implementation of parallel space switching it is expedient to use decentral control means. The circuit of the matrix switching system implementing parallel switching is presented. Functioning of similar system is impossible without synchronization of arriving loading – information packets with the switching moments in system. For synchronization of the arriving data with the moments of establishment of connections the storage devices sometimes named the buffer can be used. In this case, the storage device should accept all data packet, to write down it in storage, and then to transfer it in switching system at the moment of establishment of connections. A lack of such method is necessity of storage of all data packet that causes a delay. For synchronization of the arriving data with the moments of establishment of connections the shift registers accepting sequentially arriving given and delaying them till the moment of establishment of connections can be used also. A lack of such method is the impossibility of tracing of the beginning of a data packet, on various lines on various shift registers data packets can come at various times. In article the description of the device is presented, allowing to carry out a time delay of sequentially transferred data packet with tracing of its beginning till the moment of establishment of connections by switching system, that is synchronization of arriving data packets with the switching moments in space switching systems.
