The problem with this is that the end-to-end packet delay can vary greatly, and data becomes increasingly stale as the backlog of packets to be transmitted builds up. Active Queue Management continually measures the packet delay through the modem and rather than let the backlog of packets build up, it ensures that the delay through the modem is kept constant by dropping packets early if required.

QFlex-400 and Q-Lite Satellite Modem Installation and Operating Handbook 7.8.10.3 Priority What happens when excess bandwidth does become available (i.e. all guaranteed bandwidths are being met and there is spare capacity) in the situation where several streams have BIRs set (meaning that they are all potentially competing for the same excess bandwidth)? This is determined by the stream Priority setting.
Page 149 QFlex-400 and Q-Lite Satellite Modem Installation and Operating Handbook Each address has an associated subnet mask that delimits the particular host subnet from the overall network. If matching on a port is also selected, then the packet will only be classified as part of the data stream if both the address and the port number match.

In another example, assume Class 2 is being received at 45% and Class 1 at 70%. In this situation the Class 1 data stream will be allocated 60%, its maximum, while Class 2 will be allocated only 40%.

Paired Carrier+ has a minimal impact on Eb/No for a desired BER but typically between 0.15dB and 0.5dB extra carrier power is required to be transmitted on satellite to overcome the imperfections in the signal cancellation process.
Page 162: Antenna Control
QFlex-400 and 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 set to represent the demodulator AGC level, the Rx composite power level, the Rx wanted signal level or the receive Eb/No level (the last two of which are only available when the demodulator is locked).

Page 164: Beacon Receiver
QFlex-400 and Q-Lite Satellite Modem Installation and Operating Handbook 7.12 Beacon Receiver The QFlex-400 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.
Page 165: Point-To-Multipoint Interoperation With Qmultiflex-400 Hub
QFlex-400 and Q-Lite Satellite Modem Installation and Operating Handbook This feature is useful when deploying a satellite terminal, allowing the user to correctly identify the satellite that antenna is pointed towards. While active, the beacon detection interferes with the normal demodulation process of the modem but since beacon detection is normally a deployment activity prior to establishing a working service, this restriction should not be an issue.
