Purpose: For information 
Body: Thank you for your liaison statement "COM 15 - LS 78 - E", "Lambda Switch Capable Equipment", and your review of the CCAMP document "Generalized Labels for G.694 Lambda-Switching Capable Label Switching Routers".

Based on the suggestions provided by ITU-T Q6/15, the following modifications were made in the CCAMP document:
 
   - Reference to G.694 has been removed in title of document.
   - Reference to "G.694.1" or "G.694.2" was adopted to replace references to "G.694" in the draft accordingly.
   - The term "DWDM" was replaced by "DWDM multiplexer & demultiplexer" in Clause 3 and Figure 1.
   - "tables" is replaced by "grids" in Clause 4.1.
   - The current format of the wavelength label is the following, a new field "Identifier" is introduced.
    0                   1                   2                   3
    0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
   +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
   |Grid | C.S   |    Identifier   |              n                |
   +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
  
As you noted, this is slightly different from the information ordering in G.697. For protocol encoding, we have chosen this representation. All the functionality is supported semantically.
   
We also would like to thank ITU-T Q6/15 for the comments on the modelling of 1R, 2R and 3R regenerators in ITU-T Recommendation G.680. We would appreciate it if you would continue to inform us on the progress of ITU-T G.680.

We look forward to continuing our exchange of information with you on these topics.
