Xihua,

The model was more or less agreed during unofficial meeting during last 
IETF in Atlanta. Of course it is open to debate and can be extended or 
changed as we see fit.

The reason why it is there if I am not mistaken is two-fold:

- First, as a component that, bound to a fiber, defines the working 
region / spectrum of the TE link, as discussed in the previous section.

- Second, as the filter component that can be configured to filter a 
frequency slot that is then the input of the matrix channel.

We can change it if the agreement is not correct (for example, if the 
filter component is part of the elements that constitute the matrix 
channel). What would you propose instead? I am not sure I understand 
your suggestion. Maybe it should be made clear that the box with a X is 
just a functional element able to switch a frequency slot from one input 
port to an output port. On the right hand side, there is also the MUX 
function.

Thanks

R.
