no i wasn't sure either, as i couldnt see anything concrete in the documentation..
although from memory sinet does appear to define fttp gea, g.fast gea, fttc gea & ethernet gea cablelinks separately.
the first time i became aware that they were separate entities was when it was given as the reason for delay for g.fast installation.
it wont be an issue for WBC & WBMC isps as BTw will purchase the relevant cablelinks.
that snippet of info you found, tends to imply that some L2S's are dedicated to fttp and some may support both fttp and fttc?
