ABSTRACT:
A telephone exchange which includes a register having a number of sections in each of which information about a call may be registered; a signal interface unit corresponding to each register section; a time-shared highway; a logic network connected both to the register and to the highway; and a scanner which scans the register sections simultaneously with the interface units corresponding thereto. The units serve as an interface between the time-shared highway and other apparatus (mainly supervisory sets) in the exchange. Information from a caller reaches a register section by way of the time-shared highway and the logic network. Information is processed in the logic network as and when appropriate.
