    QubeFlex Satellite Modem Installation and Operating Handbook Chapter 7 Modem Concepts 7.1 System Clocking The following sections are most relevant where serial terrestrial data interfaces are used. When the terrestrial interface is IP, the Tx clock source should be set to ‘Internal’ and the Rx clock source should be ‘Satellite’.

    QubeFlex Satellite Modem Installation and Operating Handbook 7.1.2 Receive Clocking There are three receive clocking modes that are used in the modem. 7.1.2.1 Satellite When Satellite is selected, the modem disables the Rx Doppler buffer and derives a clock from the incoming satellite signal. This means that the signal will be subject to Doppler/plesiochronous offsets.

    QubeFlex Satellite Modem Installation and Operating Handbook Chapter 9 Data Interfaces The modem provides Ethernet IP interfaces as standard plus options for LVDS and EIA-530 (RS422, V.35, and RS232). There are two terrestrial interface positions on the modem other than the standard IP interface.

As an estimate, assume the maximum rate halves as the distance doubles (i.e. 5Mbps to 20m, 2.5Mbps to 40m etc.). Similarly, the maximum data rate increases as the connecting cable length is reduced (i.e. 20Mbps to 5m, 40Mbps to 2.5m).
