Application of an International Signaling Standard to Government Networks

This paper examines the adaptation of the CCITT No. 7 international common channel signaling (CCS) standard to the Defense Switched Network (DSN). CCITT No. 7 common channel signaling is directly applicable to the future DSN because it can provide a powerful tool for the processing of military calls and features, and appears to be evolving as the standard signaling technique for future commercial networks. First, a brief evolution of common channel signaling is given. Then, an overview of the CCITT No. 7 signaling system is presented. Finally, a description of the methodology used to tailor the No. 7 system to meet the military-oriented signaling requirements of the DSN network is addressed. The considerations discussed in this paper, which relate to the meeting of operational objectives by capabilities above those required for basic telephone service, would also apply to the signaling plans of other government networks with unique user requirements and special features.
