E.1.2 T2-Lite
Tables
and
shows which Pilot Patterns that are allowed for a given combination of FFT
and Guard Interval. For table cells without any Pilot Patterns, the combination of FFT size and
Guard interval is not allowed.
For T2-Lite FFT sizes 32k and 1k is not allowed, and thus have no allowed Pilot Patterns. Also,
Pilot Pattern 8 is not allowed for any mode.

E.2 Physical Layer Pipe
The following validations applies to each Physical Layer Pipe (PLP).
The availability of FEC Code Rates for each PLP depends of the selection of the T2-Base or
T2-Lite profile as follows. An
x
marks a valid mode.
