01/2017 – 01/2019 Federal Aviation Authority (FAA)/Select Group

System Integration Engineer Ashburn, VA

Proved the Federal Aviation Administration’s (FAA) Flight System for 21st Century (FS21) Automated Flight Service Station (AFSS) could process Voice over IP (VoIP) capabilities using their existing infrastructure. Using a custom radio interface unit built by Harris Communications specifically for this project, used ED-137B VoIP standards to prove that the FAA can replace push to talk (PTT) communications for ground control to small and medium sized aircraft across the existing FAA Telecommunications’ Infrastructure (FTI) using VoIP.

Built a custom lab using the existing FAA Voice Communication Subsystem (VCS) channel bank and DSX/DNX/X-connects, connected a Cisco 3800 router and Cisco Catalyst switches through a FirePower firewall, configured and installed hardware and software from GL Communications including a VQuad dual universal telephony adapter (UTA) to generate Push to Talk (PTT) voice through a custom Harris ED-137B VoiP convertor and ported the traffic into a GL WAN emulator for cleaning the voice traffic while inserting channel impedances for latency, and jitter. After the custom Harris device converted G.711 and G.722 to ED-137B VoIP, the standard VoIP protocol being used in Europe, it generated, measured, and recorded the signaling and voice channels of live air traffic while comparing mean-opinion scores (MOS), latency, jitter, and bandwidth utilization. Also responsible for Python scripting for data adherence during import and presentation activities.

Ancillary projects included upgrading all Wireshark and SolarWind modules to the latest releases in new server platforms including transferring all user and historic data for each module (Network Performance Manager (NPM), Network Configuration Manager (NCM), User Device Tracker (UDT), Network Traffic Analyzer (NTA), and Network Topology Mapper (NTM) to map and monitor FAA network infrastructure in the AFSS lab and the FS21 data centers in Ashburn, VA (DCA) and Fort Worth, TX (FTW).
