Abstract: A number of factors, including network topology, traffic characteristics, switching technology, and transmission media, affect the choice of control signaling techniques to be used in networks of the future. In this report these factors are considered from a military standpoint. It is projected that, over the next two decades, all of the elements of military networks will undergo a transition from essentially all analog to all-digital systems. It is also possible that a unified integrated network capable of handling digital voice and data could evolve. During the forthcoming period of transition, as well as for the ultimate network configuration, the control signaling system will play a critical role in terms of both performance and cost. This report examines that role by evaluating several advanced signaling systems, particularly those using common control links. Digital systems that have potential application on both the line and trunk sides of the digital switch are examined.
