Lazarus, what is the interplay or relationship between this out of band channel scheme, to any standards-based approach, that you can think of?
More to the point, the ITU along with the list of usual other suspects has been working on an "overhead" channel, or one that would be used for surveillance and management. This is a lambda which sits over and above the normal L and C bands, the latter two being those which are used today in DWDM spectrum grids.
I suspect that this o-h channel, or wavelength, as it were, could also be used for exchanging configuration and mapping purposes, as well. I don't know this for a fact yet, but I suspect. Any ideas in this respect?
For those lurkers who don't know what "out of band" and "in band" signaling are, in the out-of-band sense we're referring to using one of the channels (wavelengths) exclusively for management purposes (or using a common wavelength which has been assigned to multiple fibers or bundles of fibers) as a traffic cop, overseeing performance and directing traffic in the mix. In other words, and as an example of this, being able to control which incoming channel to the mux is connected to which outgoing channel. There would be many more uses.
