OM20 Universal Outdoor Modem
In addition, monitoring features provide verification of BUC and LNB status. The OM20 monitors
both the current and the voltage at the output of the TX and RX Ports, thus allowing the user to
monitor the operating status of BUC and LNB.
Redundancy for the OM20 is supported by the OMS11, Outdoor Modem Switch. OMS11 offers
redundancy for Data and supplies power for switching TX and RX Waveguide switches. For
additional information, refer to TM133 OMS11 Operational Manual.
Radyne's OM20 Ethernet Graphical User Interface (GUI) offers browser based control of the
OM20, BUC, and LNB with numerous user-friendly GUI programmable functions (see Figure 1-2).
The OM20 GUI provides selectable functions for different services: Intelsat IDR and IBS, as well
as closed networks. All of the configuration and Monitor and Control (M&C) functions are
available using the GUI (Ethernet J4) or is also available using the conventional RS-232/485
terminal port (J2). Operating parameters, such as variable data rates, FEC Code Rate,
modulation type, IF Frequencies, IBS/IDR Framing, and interface type can be readily set and
changed by earth station operations personnel, using either the GUI or terminal interfaces.
