Digital Terminations and Digital Signal Processing

  • David G. Messerschmitt
Part of the Applications of Communications Theory book series (ACTH)


An important aspect of digital switching is that the distinction between where the digital switch ends and digital transmission begins is very blurred (hence the term “integrated transmission and switching”). Many functions which were once thought to reside in the transmission world are now included in the switching system. The purpose of this Chapter is to describe many of these transmission functions, including the interface to digital transmission facilities in both the trunk and customer loop plant. These interfaces are the digital counterparts to the analog terminations described in Chapter 7 of this volume. Other transmission functions such as tone generation and detection, echo suppression, echo cancellation, and digital filtering, which are advantageously implemented in the context of a digital switch, are also discussed in this chapter.
