IN-BAND RATE {150, 300, 600, 1200, 2400, 4800, 9600, 19200}
Allows the user to select the rate of in-band data for the
ES to ES, Async overhead channel. Only displayed
when Effiecient D&I with Esc Enhanced are selected.
SCC CTL RATIO {1/1, 1/2, 1/3, 1/4, 1/5, 1/6, 1/7}
Allows the user to simulate the framing used by the
Satellite Control Channel Option (Pass Thru Mode only).
The SCC CTL RATIO is the ratio of overhead in-band
data to synchronizing words.
Only displayed when SCC Framing is selected.
SCC INBAND RATE {300 to 200000},
Allows the user to request the rate of in-band data for
the overhead channel.
Only displayed when SCC Framing is selected.
TERR FRAMING {NONE, 188, 204}, when using DVB Network Spec
DATA POLARITY {INV. TERR & BASE, INV. BASEBAND, INV.TERR
DATA, NONE}
Allows the user to invert the Rx Data polarity.
SYMBOL PAIR {NONE, SWAPPED}
Allows the user to swap the I & Q Channels, when using
BPSK Modulation.
ESC OVERHEAD {VOICE X2, DATA 64KBPS}
IDR ESC Channel used for Voice or 64 K data channel.
Only available when IDR Network is selected.
REED-SOLOMON (menu) These selections are visible only when the Reed-
Solomon Option is installed.
ENABLE/DISABLE {ENABLED, DISABLED}
Allows the user to Enable/Disable the Reed-Solomon
Encoder.
RS RATE {Refer to Table 3-1 for standard n/k values}
Displays the currently used n, k Reed-Solomon Codes.
In Closed Net Mode and using the appropriate hardware,
the user may select custom R-S Codes.
INTERLVR DEPTH {4, 8, 12}
Allows the user to select the Reed-Solomon interleaver
depth.
