The book “ISDN D-Channel in Dialogue” is intended to provide an insight into the functioning of ISDN. Whosoever is informed about the D-Channel and knows the “vocabulary” involved is likely to be well versed in the domain of ISDN. The colloquial presentation and the learning software supplied along with the book ensure and facilitate acquisition of fundamentals without whose knowledge a meaningful involvement in ISDN work is not possible. The author, Studiendirektor Dr.-Ing. Joachim Göller, has been engaged in several educational endeavors centering round ISDN. His didactic approach to present even complicated technical contents in a rather commonly accessible language has rendered his work quite effective.
