Q-Lite Satellite Modem Installation and Operating Handbook 6.2.3.13 MPE MAC Address Format 00:11:29:00:F0:23 example: Description: For DVB-S2 IP services, this is used for filtering of Multi-Protocol Encapsulation (MPE) packets on the receive side. The receiver will filter against whatever MAC address has been provided, which can therefore be a virtual MAC address rather than the receiver’s address.

Q-Lite Satellite Modem Installation and Operating Handbook 6.2.4.1 Terrestrial Buffer Size The terrestrial buffer is used to buffer IP packets coming into the IP terrestrial ports for transmission over satellite. Satellite delay and the quality of the service in general can be controlled by the size of this buffer in conjunction with setting the size of the satellite buffer.
Page 98 Q-Lite Satellite Modem Installation and Operating Handbook performance at the application level suffers due to excessive buffering of packets during periods of congestion, leading to extremely high latency levels with old data being kept almost indefinitely in the hope that extra bandwidth will become available and any overload will ease.

Q-Lite Satellite Modem Installation and Operating Handbook Chapter 7 Modem Concepts 7.1 System Clocking There are two terms commonly used when referring to the receive buffering, namely Doppler and Plesiochronous. Doppler: Receive Doppler buffering is required because the incoming data from the satellite is subject to Doppler shift, which occurs in an approximately 24-hour cycle.
Page 153: Transmit Clocking
Q-Lite Satellite Modem Installation and Operating Handbook 7.1.1 Transmit Clocking There are three transmit clocking modes that are used in the modem. 7.1.1.1 Internal Clock When Internal is selected, the modem, which is always configured to be a Data Communications Equipment (DCE), supplies the clock. This is provided by the modem to the Data Terminal Equipment (DTE) via the External Transmit Clock (ETC) signal line for using in clocking the data through to the modem.

Q-Lite Satellite Modem Installation and Operating Handbook 7.1.2 Receive Clocking There are four 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.

Page 158: No Clock Loop
Q-Lite Satellite Modem Installation and Operating Handbook rule of thumb, 2ms end-to-end buffering should be sufficient for one satellite hop and 4ms for a round trip where twice the Doppler shift is required. Set the Tx and Rx clocks as follows: When the clock is provided via the terrestrial interface Set Tx clock to Tx clk in and Rx clock to Tx clk in.

Q-Lite Satellite Modem Installation and Operating Handbook For end-to-end buffering, with a Doppler allowance of 2ms: Bs = 0.002 + 172800 x Ms x (Lc + Rc) seconds. Using the bracketed example figures above gives a result of 0.00898 seconds, requiring a buffer size of 9ms to absorb the plesiochronous effects.

Q-Lite Satellite Modem Installation and Operating Handbook 7.6 LinkGuard™ Interference Detection LinkGuard™ is a Paradise patent-pending technology for detecting in-band interference underneath satellite carriers while remaining on traffic. A visual indication of any unwanted interference is provided through a signal-under-carrier spectrum web graph showing the wanted carrier along with any unwanted interference.
Page 166: Fastlink Low-Latency Ldpc
Q-Lite Satellite Modem Installation and Operating Handbook LinkGuard™ detects various forms of interference including tonal interferers (such as CW), radars, Wi-MAX, jammers and other modulated carriers including adjacent interfering carriers. If there is more than one source of interference then it will detect and display all of them.
Page 167 Q-Lite Satellite Modem Installation and Operating Handbook If one FEC is to be used in place of all others then Paradise believes you should choose one with flexible configuration as opposed to a fixed set of modulation and code rates that are inevitably a compromise.

Q-Lite Satellite Modem Installation and Operating Handbook 7.8.2 IP Addressing The Ethernet ports on the 4-port Gigabit Ethernet switch are always bridged together.

Q-Lite Satellite Modem Installation and Operating Handbook 7.10 Paired Carrier™ Paired Carrier™ can be used to reduce satellite bandwidth requirements by up to 50% by overlapping transmit and receive carriers in the same space segment. It uses ViaSat’s patented PCMA technology. Adaptive self-interference cancellation is used to subtract the unit’s transmitted signal from the composiste received signal, leaving just the desired...
Page 187 Q-Lite Satellite Modem Installation and Operating Handbook Figure 7-16 Q-Lite™ Modem Paired Carrier Processing Paired Carrier™ can be added to existing systems as well as being incorporated into the design of new systems. The signal cancellation techniques used guarantees at least 25dB (typically 30dB) cancellation of the unwanted signal meaning that the uplink and downlink signals can share the same space segment.
Page 188 It is used in addition to, not instead of, other bandwidth saving techniques. Paired Carrier™ and DVB-S2/S2X represent two of the most bandwidth-efficient technologies available today and can be used together in the Q-Lite™ modem. Some frequently asked questions about Paired Carrier™ operation along with answers are provided below.
Page 189 Paired Carrier™ need to be set up. Set up takes less than five minutes in total. Q. Is Paired Carrier™ available as a field upgrade? A. Yes. All Q-Lite™ modems can be field upgraded to support Paired Carrier™ operation to the desired cancellation bandwidth.

Q-Lite Satellite Modem Installation and Operating Handbook 7.11 Antenna Control Two methods of antenna control are provided by the modem: A scalable (0 to 10V) AGC output is available via the Alarms & AGC serial • connector (the pinout for which is defined in Chapter 10). The AGC output can be...
Page 191 Q-Lite Satellite Modem Installation and Operating Handbook Pin 3 provides an indication for Rx traffic faults, the highest priority fault of which is • a demodulator unlock (so the alarm output approximately amounts to a demodulator lock/unlock status). Since this is a relay output, the relay common on pin 2 needs to connected to GND (pin 15).
Page 192: Beacon Receiver
Q-Lite Satellite Modem Installation and Operating Handbook 7.12 Beacon Receiver The Q-Lite modem supports a beacon receiver mode of operation as standard. The beacon receiver support in the modem can help with automatic antenna pointing when attempting to lock onto a satellite. This modem feature negates the need for a separate beacon receiver.

Once the signal has been peaked it is possible to determine the beacon carrier-to-noise measurement by analysing the spectrum graph data and looking for maximum and minimum signal levels.
