HSSI Data Rate Limit of 1 Mbps is violated with QPSK 1/2 at 1Msps, so the minimum symbol rate is
1.011270 Msps (pilot
off
) and 1.035920 Msps (pilot
on
).

* Notes:
1.
DVB-S2 - Short FECFrame = 16,200 Bits.
2.
For G.703 fixed Data Rates, limit maximum Symbol Rate to less than the maximum indicated in
Table 6-2
.
For more information on this interface, see
Chapter 12. SINGLE G.703 (E3/T3/STS-1) INTERFACE
(CDI-10-1)
.
3.
HSSI Data Rate limit of 70 Mbps may be reached before Symbol Rate limit is reached. For more
information on this interface, see
Chapter 13. HSSI INTERFACE (CDI-60)
.
4.
HSSI Data Rate Limit of 1 Mbps is violated with QPSK 1/2 at 1Msps so the minimum symbol rate is
1.178079 Msps (pilot
off
) and 1.203980 Msps (pilot
on
).
