    Within each service both manual and hot-line access modes are supported for channel activation. In addition to the standard Saturn B installation, the Enhanced Bitrate Module (EBM) consists of an Interface Converter Unit (ICU), and an external modem unit (Comtech CDM-550T).

  • Page 36: Interface Converter Unit - Icu

    The ICU is either in normal mode (regular Inmarsat-B or Inmarsat CN17), or in EBM mode. In normal mode the Saturn B MCU is directly connected to the antenna RX and TX paths, and the Comtech CDM-550T Modem is disconnected.

    • When Saturn B acknowledges the command, the ICU switches the Comtech Modem into the RF path. The indicator lights steadily. • At the same time Saturn B turns the antenna high power amplifier ON establishing the satellite circuit. • The pre-programmed Comtech Modem is now connected to a similar modem at the LES end.

  • Page 59 • During a manual call from ICU, an event such as rewind forces the Saturn B terminal to clear the channel causes the MCU to issue a ‘NO CARRIER’ result code to the ICU. The ICU then immediately disconnects the Comtech Modem from the antenna and reverts back to normal mode.

  • Page 60: Demand Assignment Services

    The modem will then accept subsequent configuration command strings on its RS232 Remote Control port. This is achieved by connecting an RS232 cable between this port and the Saturn B PC port. The Saturn B reprograms the modem with channel numbers and data rates every time a satellite connection is being established.
