Abstract
The engineering of a data system for use on the switched message network is reviewed. First, the conditions imposed by this specific application are shown to influence the selection of signal characteristics, and the choice of raised-cosine pulse shaping is given support by a brief treatment of some pulse transmission fundamentals. Finally, the results of a field trial are summarized to show that, while the system objectives were met, factors such as delay distortion, attenuation distortion, and transmission loss limited the performance obtained.
