Thank you for your replies Chuck and Cedric. I think it will be helpful to
speak to some vendors or tech support with these types of products, and I
will try to give them a call in the next few days. Hopefully I can find
something that won't be too pricey :-)
Regards,
Steven

My experience has been that specific purpose hardware is required --
on my old Redwood system (oog. Anyone miss those? If so, I have
one ... :) there were specialized cards that provided "OPX" (Off-
Premise eXtension) ports for such purposes.
This OPX line box (Model# 46222 & 46224 Long Loop Adapters) are
specified to provide a 30 kft line length. (No Idea on price, No
Personal experience with the product -- found on google :):
http://www.proctorinc.com/46222.htm
These fellows comment specifically on the above (they say the
46222/46224 don't pass caller id, for example), and provide various
technical tidbits, etc. Like BlackBox, they also seem like they
would be the sort of people you could call and talk to:
http://www.sandman.com/longloop.html
A similar box that does it over fibre (less likely to be helpful here):
http://www.arcelect.com/Fiber_Telephone_modem_Line_Extender.htm
Also, a range of Wireless Boxes (using things like CDMA as the link-
level protocol) -- kinda pricey, and not likely to be your best fit:
http://www.oksolar.com/n_cart/search.asp ?
cat=Communications&subcat=Phone%20Extender
Especially with the first two pages, there should be more than enough
key words to ferret more info out of Google, and there's a few people
that would be promising to call, etc.
I hope that helps!
Best Regards,
