National Airspace System (NAS) Voice over IP Communication Enterprise (VoICE) 

Jon Shedden is the Article 114 Representative to the VoICE project.   

Background:  The National Airspace System (NAS) Voice over IP Communication Enterprise (VoICE) program will encompass what was the NVS program. This will include acquisitions to replace our aging voice switches, as well as Radio Control Equipment (RCE). The FAA released a second Request for Industry (RFI) with more detailed questions regarding the voice communications system. The FAA has also released a Screening Information Request (SIR) to purchase small Commercial Off The shelf (COTS) voice systems. The FAA intends to use these systems to revise and update requirements for the Voice Communications System Specification to better align with existing industry standards.   

Alaska Flight Service was scheduled to have their aging voice switch replaced with NVS. Now that the NVS contract has ended, work has begun to find a suitable replacement. Work continues on a shortfall analysis, Operational Needs Assessment (ONA), as well as requirements review. 

The FAA is in the early stages of a technical refresh of the Small Tower Voice Switch (STVS). There are approximately 130 STVSs across the NAS. The FAA and NATCA are working collaboratively on the controller’s human machine interface for the refreshed panels.  

The Voice Switch and Control System (VSCS) Training and Backup Switch (VTABS) is scheduled for replacement of the PECO Power Subsystem at all ARTCCs. A national SRM panel was held remotely on April 7th. The replacement will result in VTABS being unavailable for up to 3 days at each ARTCC. A significant amount of prep work will be done at each ARTCC to ensure the availability of VSCS during the installation.
