Abstract

1500696 Time-division multiplex systems SIEMENS AG 5 Sept 1974 [5 Sept 1973] 14567/74 Heading H4M In a time-division multiplex (T.D.M.) pulse system between subscribers lines 1 to 20 are grouped, each group has a common T.D.M. unit SMUX having information a ... e and synchronizing channels f, an enciphering unit VS and an adder A; a circuit SZ combines the groups and includes a unit SYN for each group which holds the synchronizing information from onward transmission and a unit AB which gates for onward transmission only the bit sequences corresponding to lines a... e, stores SSP, and a scanning switch AT.
