Tandem Electronic Voice Switching (EVS) System.

摘要

The Tandem Electronic Voice Switching (EVS) System Project Plan identifies responsibilities and describes events and activities which must be completed in order to integrate the Tandem EVS System with NAS En Route Stage A. Initial emphasis is on the installation and evaluation testing of a preproduction EVS System at NAFEC for which the System Research and Development Service has primary responsibility;however,the plan also addresses the implementation of production systems and provides for the transition of primary responsibility to the Airway Facilities Service for this activity. The Tandem EVS System Project Plan does not assign responsibilities,but rather amalgamates and synchronizes,the planning of participating organizations with respect to their inherent responsibilities for the Tandem EVS Project.
