The unit can work as a modulator, demodulator or modem depending on the network configuration and integrates seamlessly with terrestrial IP networks and equipment. The modem is in full compliance with the DVB-S2 and DVB-S2X standards to achieve barrier-breaking efficiency at maximum service availability.
