That only works if your customers don't use their Internet access very much. If they do, you're in trouble and have to rebuild. In my market, we're now in the access speeds where 100/10 is on the lower end of access, and it's not uncommon for people to have 250, 500 or 1000 downstream. If they then actually start using their bw then you'd have to rebuild to either go higher speed for some CPE (complicated and expensive), or rebuild to have smaller splitter domains. I guess the answer depends a lot on your cost of labour. -- Mikael Abrahamsson email: swmike@swm.pp.se
