Re: Comments on ITU's Work Plan for Optical Transport Networks

OK.

Thanks, I will point at the I-Ds, summarise how we are splitting RWA for 
immediate attention and impairments for future work, note that we do not 
intend to define impairments (but will defer to the ITU-T on this), and 
comment that we believe that the modeling of asymmetric switches such as 
ROADMs may be an area that the ITU-T would like to work on.

Cheers,
Adrian
