Abstract
Digital code words are transmitted via a digital communication network, e.g. from a digital modem ( ) to an analog modem ( ). Whenever an RBS technique is used for an RBS channel, a given bit, as a rule the LSB, of a corresponding code word is changed. In order to recognize and correct such RBS channels, training code words transmitted during a training phase are evaluated. If an RBS channel is detected, the given bit of the corresponding code word is set to a fixed value.
