ABSTRACT:
A method and a device is described for the regeneration of asynchronous data signals of a given character structure which arrive on a transmission line time distorted and at a signalling rate which deviates from the nominal signalling rate and after detection are fed to a regeneration device at a character rate determined by the arriving data signals, the data signals then being retransmitted at a signalling rate determined by a timing generator included in the regeneration device. In order to reduce variations in character length of the retransmitted data signals, at least part of the characters fed to the regeneration device are stored temporarily while a preceding character is being retransmitted, and the length of a retransmitted character is shortened in dependence upon the separation in time between the beginning of a character fed to the regeneration device and the expected ending of a character in progress of retransmission, the degree of the shortening being determined by the relation of the time separation to a definite time limit.
