Purpose: For information

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 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 modeling
of 1R, 2R and 3R regenerators in ITU-T Recommendation G.680. We would
appreciate it if you would continue to providing us on the progress of
ITU-T G.680.

We would like to inform you that the CCAMP Working Group ???...

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