Re: alternative to voip gateways

[Mike Hammett <nanog () ics-il net>]

If you were to outfit them with three chassis of Calix\Occam B6-252s, you'd be under $25k for the whole thing and get 
ADSL2+ speeds. You would need most of a rack to do it. 


Other platforms may or may not be more cost effective or a better solution. Just throwing the idea out there.

The huts or cabins whatever you want to call them, are right behind 
the admin building at entrance, so first is about 300 meters and the 
furtherest is just under 1 mile 

Cost will be an issue, Im sure I will have no problems if I have to 
install a full rack of gateways and another full of dslams if it costs 
150K, over something 1/5th the size in one rack that will cost 200k - 
since the company is not charging them for internet or voice.
