HP – 1/2; 2/3; 3/4
RS
Reed-Solomon Decoder: On or Off.
Diff
Differential Decoder: On or Off.
Descram
Descrambling:
•
V.35 – ITU standard;
•
MOD-V.35 (modified V.35) – Comtech EF Data Closed Network with Reed-Solomon
compatible;
•
IBS – Used for IESS-309 operation;
•
Turbo – Synchronous descrambler synchronized to the Turbo block;
•
OM-73 – OM-73 Linkabit modem compatibility mode;
•
Synch – Synchronous descrambler synchronized to the Reed-Solomon frame.
•
Off – Descrambling is disabled.
When changing Modulation type, the data rate must be set to a rate supported by the modulation
type, or the change to the modulation type will not be allowed. Some choices will only be visible if
the modem is set to a compatible mode, or if an option is installed or enabled.
