The details about this are very vendor-specific, and each vendor has
some way in which they implement this. Spectrum would be a very
customized product between the vendor and operator, and also between the
operator and customer. So no BCP for this, as of yet, that I know of.

We are seeing requests from as low as 600km, up to 1,600km, all the way
to 7,000km.
