11.3 End-to-End Processing Delay (Latency)

For DVB-S2 operation with the Gigabit Ethernet and HSSI Data Interfaces, the effects of delay
through the modulator and demodulator are more problematic at low data rates and generally
negligible at higher data rates.

Delay for the Gigabit Ethernet and HSSI interfaces is shown in

Figure 11-5

and

Figure 11-6

with

the Rx Buffer (HSSI) at minimum. In packet networks, minimum Rx Buffer is the normal setting.
Expected performance for the G.703 interface is similar to HSSI.
