correct frequency is made. This requires the receive buffer to be
set as per the Tx Clock In option.

FastLink This enables Paradise’s FastLink low-latency Low-Density Parity-
Check (LDPC) FEC. FastLink gives BER performance
approaching that of conventional LDPC but with latency nearer to
that of TPC. In addition, FastLink supports modes (available on the
Edit->Tx-Rx->Service->Advanced menu) that optimize either BER
performance or latency even further, giving the flexibility to match
performance more closely to the constraints of the satellite
application.
SmartLink This selects SmartLink, which extends DVB-S2 from working with
only packetized data such as IP to working with any terrestrial
interface. Using SmartLink in Closed network provides a normal
DVB-S2 service (with no additional overhead). However,
SmartLink can also support the use of traditional service features
not normally available with DVB-S2, such as Drop and Insert, ESC
channel, remote M&C control, AUPC, IDR audio channels, etc.
SmartLink is described in Section 7.9.
TPC This selects the Turbo Product Code (TPC) FEC.
Viterbi This selects the Viterbi FEC.
TCM This selects the Trellis Coded Modulation (TCM) FEC.
Sequential This selects the Sequential FEC.

6.2.4.10 Tx/Rx Modulation
The modulations that are available depend on the FEC type selected. The supported
combinations are listed in Table 6-9.
6.2.4.11 Tx/Rx FEC Code Rate
The FEC rates that are available depend on the FEC type and modulation that are
selected. The supported combinations are listed in Table 6-9.
