ITU-Action on Liaison Statement
ITU management referred the liaison to four ITU-T questions:
SG15Q12* - Transport network architectures
This group has met and made a proposal.
SG15Q11 - Signal structures, interfaces and interworking for transport networks
This group endorsed the SG15Q12 proposal
SG15Q9 - Transport equipment and network protection/restoration
This group endorsed the SG15Q12 proposal
SG13Q5 - OAM and network management for NGN
Not yet met - see label 14 concerns
Note that SG15Q14 is also doing work on TMPLS.

*ITU would write this as SG12/15, however it is pronounced in the pneumonic form used in these slides.
