{1/2, 2/3, 3/4, 7/8, 19/20, None}
IFEC INTERLEAVER {DISABLE, ENABLE}
Disable or enable the IFEC Interleaver.
DIFF CODING
{ENABLED, DISABLE}
Enable or disable the Differential Encoder. Having
the encoder enabled ensures proper phase lock.
May not be adjustable in some modes.
SCRAMBLER SEL
{NONE, V.35-IESS, V.35 CITT, V.35
EF, IBS w/Optional Framing and
optional Reed-Solomon, Reed-
Solomon Scrambler w/Optional
Framing, CCITT, V.35FC, OM-73,
V.35EF_RS, TPC SCRAMBLER
(Turbo Codec), DVB, EDMAC, EBEM}
Select the scrambler type.
SCRAMBLER CTRL
{ENABLED, DISABLE}
Enable or disable scrambler operation.
SAT FRAMING
{1/15 (IBS), 1/15 (Async), 96 Kbps
(IDR), DVB, EDMAC, EFAUPC, SCC,
NONE, EFFICIENT D&I, EBEM,
None}
Select the framing type.
IN-BAND RATE
{150, 300, 600, 1200, 2400, 4800,
9600 19200}
ED&I Only
Available when enhanced async is enabled, sets
the Earth Station to Earth station in-band rate. In
most cases, this should be set to the same rate or
higher than the ES port baud rate. When this rate is
set lower than the ES port baud rate, make sure
that the actual transmission rate does not exceed
the in-band rate, otherwise, characters will be
dropped.
