SITA has made an update to their network to improve coverage for CPDLC. Since the update, coverage and message success is close to 100 percent. The program office is working with Harris and ARINC to update their system with the same enhancement. The National DataComm Workgroup has made the determination to currently suspend the Monitor Transfer of Communications (TOC) message with the Confirm Assigned Altitude (CAA) report. Pilot confusion on Boeing aircraft generated a 70 percent success rate of pilot acknowledgement. A workgroup has been formed with the DataComm Implementation Team (DCIT) to look at options to turn this service back on. ENROUTE AUTOMATION WORKGROUP (ERAW) Julio Henriques (ZNY) leads the ERAW efforts for NATCA. Rex Jackson (ZDC) provides his NATCA ERAM/ERAW Technology update below: FTR's continue to support Limited DFV testing at the CPDLC keysites. The three sites will move into 24/7 CPDLC operations over the next 45 days. Testing was completed on EAE121 and the release is now available nationally. The EAE121 release contains fixes for the Route Typing Buffer in support of CPDLC route uplinks. The National User Team received more briefings on multiple TTL issues. Included are SGET, lab "crashes" and changes to functionality that were not originally briefed. SLE is working to limit these issues moving forward. ERAW received the following briefings: The Program Office presented the R-side Tech Refresh keysite candidates and ERAW approved them. The facilities are ZFW, ZMP, and ZOB. ZFW will keysite EAE200 software and hardware due to volunteering to be the first facility to install the new hardware. A key component of the hardware will be the deployment of 43" r-side monitors. Multi Meter List concept: MITRE will schedule HITLs to gather data using ZDC Sector 16. The intent is to gather data on how many METER Lists a controller can manage in one sector at any given time. The HITL will include GIMS and Path Stretch future functionality. TBFM Ops team and National User Team will create a task team to continue working on the Path Stretch use case to be completed in early 2019. DataComm Speeds: The FAA is evaluating and prioritizing the need to add "Speeds" to the DataComm Full Services release. This functionality will allow controllers to uplink speeds through the 4 th Line functionality on the Data Tag. The following issues are examples of what the National User Team worked:
