• Abstract:
  In support of the Airway Facilities Service's program to provide Remote Monitoring Systems (RMS) at Remote Communications Air-Ground (RCAG) sites, the Technical Center was tasked to determine the necessary characteristics of external filters, modems, etc., which would enable RMS digital data transmission over existing site-to-center telephone lines in accordance with the Federal Aviation Administration (FAA) Specification FAA-E-2699a. Part of the task was an analysis of the spectrums of simultaneous speech and data transmission under several system conditions. The graphs obtained in the spectrum analysis are contained in this report.
