etherSPLIT secrets

[Tomi Holger Engdahl]

The web site at http://www.ethersplit.com/
describes an interresting technology ?

"etherSPLITtm employs a patent-pending system that splits 10BaseT
Ethernet and POTS (plain old telephone service) over four wires
(straight or twisted pair)."
"etherSPLITtm leverages all four wires in existing structures to
deliver 10BaseT (10 Mbps) Ethernet as well as one traditional POTS
line. The splitter system is enclosed in a simple wall-plate unit on
the user end that includes an RJ45 jack for Ethernet, and an RJ11 jack
for telephone. This unit, which replaces an existing telephone jack
plate, is connected through the building's existing copper wire to an
etherSPLITtm hub (or an etherSPLITtm interface unit that connects to
any standard 10BaseT hub.)"

Anyone tried tríed that technology ?

Has anyone seen what their adapter hve inside them.
Foer example their wall plate shown at
http://www.ethersplit.com/Pages/wallplatephoto.html
seem to be very simple.
What are those few components in it ?
And is the hub splitter more complicated ?

Probably just a balun, or something like the splitters used with DSL.

My thoughts are that no one will want to go back to 10 now that most
every PC has a 10/100/1000 NIC and most are running 100.

There already is DSL, and HPN. This technology will probably be as
successful as Token Ring.

Someday there will be fiber to the desktop, and copper won't be needed.

Not a balun, not a frequency splitter.

As for its uses it is used for retrofitting existing properties.
Utilitizing existing copper that cannot support 100+ megabit speeds
with standard ethernet. And using existing two pairs to split to
three pairs using standard ethernet hubs/switches and no extra power
supply needed. Apartment complexes, hotels, and cruise ships have all
been installations for this product.

As for every electrical engineer that has seen the circuit, there
first response is "it can't work".... "well, maybe".... "damn, that's
clever".
