Tx Scrambler = IESS (Normal,IESS,Off)
Use the ▲▼ arrow keys to select Normal, IESS, or Off. Press ENTER.
The modem automatically selects the actual scrambler used for Normal, depending on the exact
operating mode:
•
If framing = D&I, the IESS-309 scrambler is used.
•
If framing = EDMAC/2/3, its frame synchronous scrambler is used.
•
ITU V.35 scrambler (Intelsat variant) is the default scrambler when all of the above
settings are OFF.
When you select IESS, the default ITU V.35 scrambler specified in IESS-315 takes priority over
all "normal" scramblers and is used instead. Therefore, for many operating modes, the two
scrambler selections are redundant.
