The invention relates to a method for transmitting data between an analog modem (3) and a remote data terminal (4). The data can be transmitted at a variable sampling rate >=8 kHz by means of a PCM modulation method from the analog modem (3) to a subscriber line module (5) that is provided with a coder/decoder device (50) with a corresponding sampling rate via an analog data transmission line (1). From the subscriber line module (5) at least two data transmission links K1, K2, . . . , Kn to the remote data terminal (4) can be established in parallel. The data transmission capacity properties of the data transmission line (1) during establishment of the link are determined. The maximally possible number mmax of data symbols Sxy that can be transmitted per data transmission link K1, K2, . . . , Kn is determined. A certain number n of switched data transmission links K1, K2, . . . , Kn required for a predetermined data transmission rate is established on the basis of the data transmission capacity properties and the determined maximally possible number of transmittable data symbols Sxy per data transmission link K1, K2, . . . , Kn for producing a data transmission rate between the analog modem (3) and the remote data terminal (4) that is higher than 64 kbit/s.
