  2. Time Synchronization
    • NWS ORPG will automatically time sync with AWIPS's clock

  3. TCP/IP connection between ORPG LAN and AWIPS LAN
    • High speed dedicated connection - Once AWIPS Build 5.2.1 is available, this will support:
      • RPS lists of up to 90 products
      • transmission of high resolution Digital Base Reflectivity and Velocity products

    • Once AWIPS Build 5.2.1 is available, line #25 will connect to each office's co-located RPG.
      • Each office's other dedicated RPG connections will continue to use the X.25 protocol.
    • TCP/IP ORPG LAN to AWIPS LAN connection will eventually support real-time transfer of Archive II data to NCDC.
