SHAPING THE FUTURE OF SATELLITE COMMUNICATIONS
The EL170 offers an auto-switching Gigabit Ethernet interface and integrates
seamlessly with terrestrial IP networks and equipment. The incoming IP packets
can be filtered using e.g. VLAN or MAC addresses, transmitted transparently (data
piping mode) or routed to several receiving points and destination addresses.
The IP data entering the modulator using the Ethernet connector A is
encapsulated.
The signal is framed into baseband frames.
The framed signal is modulated by the L-band modulator.
The modulated (L-band) signal is forwarded to a multiplexer, in this multiplexer the
following options can be added:
• 10MHz reference (we refer to the section Options for ordering information);
• 24V or +48V DC Power (we refer to the section Options for ordering
information).
At the output of the modulator, the signal is available on an L-band interface, MOD
OUT and MON OUT connector.
Test Generator
The modem is equipped with a build in test generator. This generator can be used
to simulate IP data.
Option IF OUT
Optionally the L-band modulator can be replaced by an IF-band modulator. When
this option is available the IF signal is directly available on the output of the modem
as IF OUT. In this case the multiplexer is not used. For ordering information we
refer to the section Options.
This option is not shown in the block diagram.
