frame format (with overhead of less than 0.5%). The absolute minimum amount of
bandwidth is used in all cases, in direct proportion to the required number of timeslots.
5.3.2 Other Option Cards
The following feature-specific option cards are available:
•
P3609 DVB-S2/S2X option card.
•
P3605
FastLink™
option card, required for
FastLink™
low-latency Low-Density
Parity-Check (LDPC) Forward Error Correction (FEC) operation.
•
P3607
Paired Carrier™
option card, required for
Paired Carrier™
operation
(which overlays transmit and receive carriers in the same space segment reducing
the overall required satellite bandwidth).
5.3.3 BUC Power Supply Options
The
Q-Lite™
satellite modem can be connected to a Power Supply Unit (PSU) for
powering a Block Up Converter (BUC). Refer to
Table 5-1
for the available Paradise BUC
power supply options. The BUC PSU is a separate item from the satellite modem circuit
board and therefore space must also be assigned in any custom enclosure design for the
BUC PSU.

5.4 Software Options
Several software options, known as Software Activated Features (SAF), are available as
shown in
Table 5-2
. These can be purchased on a pay-as-you-go basis and
retrospectively activated in deployed units as required. The SAF concept (including time-
limited free access to most features) is explained in
Section 8.5
.
In the table, the
SAF Code
column lists the acronyms by which features are referred to on
the modem’s local user interface.
