Abstract

1. Circuit for acknowledgement of calling signals arriving via subscriber lines supplying data signals in an incoming transmission direction by emitting confirmation signals, in an exchange in which subscriber lines provided for the transmission of data signals in an incoming and outgoing transmission direction are connected to line termination circuits which, combined to line termination groups (LTEC), are connected to the data transmission facilities (CC, Mem, CPU) controlling the data signal switching between the subscriber lines, each line termination group (LTEC) having for the subscriber lines (Lab') transmitting data signals in an outgoing transmission direction a register arrangement (Reg1, Reg2, Reg3) from which a confirmation signal is emitted immediately after detection of a calling signal and of an indication signal indicating this detection, characterized in that the confirmation signal is contained in a first register (Reg1) from which, upon the appearance of the indication signal , the relevant confirmation signal is loaded into two further registers (Reg2, Reg3), the contents of which are subsequently emitted via a subscriber line (Lab), and in that at least one of the further registers (Reg2, Reg3) serves to receive and forward data signals via said subscriber line (Lab).
