B.1

Overview

This appendix applies to both the SLM-5650C and the SLM-5650C-ODU. It provides the end user
with reference guides for the DSSS and non-DSSS LDPC modes.
The Data Rates and Symbol Rates shown in the following tables all assume that Transmission
Security (TRANSEC) is turned OFF. To calculate the max data rate with TRANSEC ON, the max
data rate shown in the table becomes a max aggregate data rate. The real data rate can be
calculated by dividing the TRANSEC overhead rate from the aggregate data rate. The TRANSEC
overhead rate can be calculated for any TRANSEC Frame Length (N) as follows:
TRANSEC Overhead Rate = (3 + 16 * N) / (16 * N) where N=8
