4.8 ksps to 3.0 Msps 

See Section 13.5 

Transparent, Closed Network, IESS-315 (VSAT Turbo) 
Proprietary EDMAC framed mode: 
  * 5% overhead - EDMAC 
     (all modes except BPSK Turbo, Rate 21/44 OQPSK Turbo, and data rates < 2.048 Mbps) 
  * 1.6% overhead - EDMAC-2 
     (Rate 21/44, 5/16 Turbo, Rate 1/2 OQPSK Turbo, and all other rates >2.048 Mbps) 
R-S Outer Codec (optional) 
  * 220,200 outer code (transparent mode)

LDPC (planned future upgrade – consult Factory for latest information) 
Automatic Uplink Power Control (AUPC) mode 
 

Per INTELSAT IESS-308 (FIR digital filter implementation)  
 

Transparent Closed Network mode, no R-S or Turbo coding - per ITU V.35 (Intelsat variant) 
EDMAC mode, no R-S coding - externally frame synchronized - proprietary 
Turbo Product Code mode - externally frame synchronized - proprietary 
All R-S modes - externally frame synchronized per IESS-308/309/310 
 

None: Uncoded BPSK/QPSK/OQPSK 
Viterbi: k=7, per IESS-308/309 
BPSK: Rate 1/2 
QPSK/OQPSK: Rate 1/2, Rate 3/4 and Rate 7/8 
16-QAM: Rate 3/4 and Rate 7/8 (requires Reed-Solomon)
