Abstract
The New York City Police Department, as do other large Communications Systems users, requires multiple telephone tie lines to its communication terminals. A public safety agency has to respond immediately to all emergencies involving the public, business, institutions, and other governmental entities. The communication system is the media for information exchange and response. Reliability has to approach 100%. In the case of the New York City Police Department, telephone tie lines were experiencing failures at critical times. The line costs of terminal equipment were escalating. The solution appears to be a multiplex microwave system designed to be fail safe, expandable and automatically shift into a redundant system. The design of this system is discussed in this paper.
