Remove the remark stated in parenthesis "(it is not applicable...)"

[Reason for Edit]
2 problems here:
(1) Due to the dynamics a temporary situation where a single modulation
scheme is being used could occur (i.e., heavy rain)
(2) FSDD is not defined in the document (see next comment)

[Detailed Description of Proposed Insertion, Deletion, Change]
Add the following after the last sentence of 3.1.2:
"Furthermore, the burst mode of operation in the FDD case can handle
subscribers restricted of transmitting and receiving at the same instant due
to their specific transceiver implementation."

[Reason for Edit]
Through the document this feature is never discussed yet it is one of the
main issues of PHY Mode B and some MAC related support.

Change "The coding rate is 2/3" to "The inner coding rate is 2/3"

[Reason for Edit]
The overall coding rate depends on the Reed Solomon parameters. The inner
coding rate is fixed to 2/3.

E

[Detailed Description of Proposed Insertion, Deletion, Change]
Change section starting with "The outer block..." and ending with "...byte
errors." To the following:

"The outer block code in code types 1-3 shall be a shortened, systematic
Reed-Solomon code generated from GF(256) with variable information block
lengths (K) and error correction capability able to correct up to 16 byte
errors."

[Reason for Edit]
Technical accuracy and ordering. There are some limitations on K which are
understood by reading the next few sentences.

[Detailed Description of Proposed Insertion, Deletion, Change]
Change "inserted as the MSB" to "inserted as the LSB"
Remove "the result is a 9(K+R) block of bits, LSB first."

[Reason for Edit]
To be consistent with p.59 l.1 which calls for a MSB oriented transport. In
most cases it would be easier to add the parity at the end (LSB) of a byte
after all bits are collected.
