Body:
ITU-T SG15 Q6/15 and Q12/15 would like to thank IETF’s CCAMP WG for its
Liaison Statement on starting work on enhancing GMPLS's support for
Wavelength Switched Optical Network (WSON) equipment to support
Flexible Grids.
Q6/15 and Q12/15 would like to inform IETF’s CCAMP WG that revised
Recommendation ITU-T G.694.1 was consented at the Plenary SG15 Meeting
in Geneva, 5-16 December 2011, introducing the concept of a flexible
grid. Furthermore a joint meeting was held between Q6, Q7, Q9, Q11, Q12
and Q14 of SG15 to discuss potential follow-up work on the flexible
grid within these questions. In order to provide some input to this
joint meeting, the Q6/15 Rapporteur and Associate Rapporteur drafted
the document, attached as Attachment 1 to this Liaison Statement,
containing some specific considerations relevant to the introduction of
the flexible grid in revised ITU-T G.694.1.
Furthermore Q6/15 would like to inform IETF’s CCAMP WG that also a
revised version of Recommendation ITU-T G.697 was consented at this
SG15 Plenary Meeting, where some of the parameter encoding was modified
to take account of the introduction of a flexible grid in ITU-T
G.694.1.
In order support the work in IETF’s CCAMP WG both consented ITU-T
G.694.1 and ITU-T G.697 are attached.
As SG15 further progresses with the work on this topic, we would be
happy to inform the IETF’s CCAMP WG about the progress made. Q6/15 and
Q12/15 are looking forward to future exchanges of information with
IETF’s CCAMP WG.

Attach:	Consented ITU-T G.694.1 (TD502/PLEN Rev.2).
Consented ITU-T G.697 (TD505/PLEN Rev.1).
