    7. Enter Normal operating state waiting for modem to receive transmit grant message from the hub Note during this process the ROSS may send a TEK message enabling carrier before the antenna has completed its tracking. In this state the ROSS relies on the hardwired transmit mute control line from the antenna controller to the modem.
  • Page 21 The file transfer uses the Comtech proprietary Streamload protocol for ROSS to push a new configuration updates. Upon complete reception the modem stores and processes the new changes issuing a firm reset to initialize the new changes. The new updates are accomplished without a reboot minimizing the transitioning time.
