Abstract
A method for transmitting data signals on analog subscriber lines wherein bilateral data transmission between subscriber terminal equipment and exchange is intended to occur, with relative ease and with low outlay, even during speech signal transmission. A signal, preferably the charge pulse signal, that is already generated at least in the exchange for some other use is employed as a carrier signal wherein, accordingly, it is possible to exploit an already existing infrastructure.
