VIT
Enables the Viterbi FEC scheme. This is provided
as part of DVB-S.
IRS
Enables the selection of the Intelsat Reed-
Solomon outer FEC. This is provided as part of
DVB-S.
WIF
Enables selection of IF frequencies betw een 100
and 180MHz. This is provided as standard.
8PSK
Enables selection of 8PSK modulation. This is
provided as part of DVB-DSNG and DVB-S2.
16QAM
Enables selection of the 16QAM FEC scheme.
This is provided as part of DVB-DSNG.
CCM
Enables DVB-S2 CCM mode. This is provided as
part of DVB-S2.
CCMM
Extension to DVB-S2 CCM mode that allows two
or more ports of the Quad ASI card to be
multiplexed together on trans mit and
demultiplexed on receive. It also allow s ASI and
IP streams to be multiplexed/demultiplexed. In
DVB-S/DSNG, this feature allow s only the Quad
ASI ports to be multiplexed/demultiplexed.
PRBS
Enables the internal Pseudo Random Bit
Sequence ( PRBS) Bit Error Rate (BER) tester.
FSK
Enables remote control of a BUC via an FSK
modulated signal multiplexed onto the IF cable.
TCP,
Enables a Performance Enhancing Proxy that
TCP16,
provides acceleration of TCP data over satellite.
TCP25,
Requires P3714 IP Traffic card.
TCP55
BRT
Enables Ethernet brouting function (w hich
supports IP traffic point-to-multipoint operation
and the use of an indirect return path). Provided
as standard.
TCM
Enables the TCM FEC scheme. This is provided
as part of DVB-DSNG.
HCP
Enables Ethernet header compression. Requires
P3714 IP Traffic card.
HCP2
Enables IP and UDP packet header compression.
Requires P3714 IP Traffic card.
WEB
Enables accelerated browsing using HTTP.
Provided free w ith the TCP acceleration feature.
