Fec-len
The Fec-len parameter is the number of data bytes (k) in the forward error
correction codeword. Acceptable values are 1 to 255. Note that this
parameter is not used if FEC-tbytes is zero.
You set the codeword length by performing the following tasks:
.
Task
1. Enter cable interface
mode.
2. Configure the
codeword length.
Seed
The Seed parameter is the 15 bit seed value for the scrambler polynomial. By
default, Seed is set to 338.
You set the scrambler seed by performing the following tasks:
.
Task
1. Enter cable interface
mode.
2. Configure the
scrambler seed value.
