Abstract
In order to improve the rapidity with which an automatic equalizer can be pulled in when transmitting data at high baud rates, each of the modems of secondary stations are arranged to detect the divergence of the automatic equalizer included therein and induce the issuance of a tone signal which is supplied to the primary station and induces the latter to reissue a training signal. The automatic equalizers in the secondary stations pull in on the training signal which ceases to be issued when the tone signal is no longer generated.
