Hi Saku, I forgot to mention, it also depends how "out" of band your OOB needs to be. We use Ciena 6500s for our DWDM infrastructure and they have a wayside channel (like various DWDM vendors), so it's a separate channel over the same physical fibre. For anything except a fibre cut it seems to work. Cheers, James.
