* Notes:
• DVB-S2 – Short FECFrame = 16,200 Bits.
• For G.703 fixed data rates, limit maximum symbol rate to less than the maximum indicated in
Table 1-6. For more information on this interface, refer to Chapter 12. SINGLE G.703
(E3/T3/STS-1) INTERFACE (CDI-10-1).
• HSSI data rate limit of 70 Mbps may be reached before symbol rate limit is reached. For more
information on this interface, refer to Chapter 13. HSSI INTERFACE (CDI-60).
