4.1 Application for home networking
The 1Mbps Modem is used to connect any device equipped with a standard 10/100Mbps Ethernet port to a
HomePNA LAN.
The Modem has been designed to operate on the telephone wire installed in homes throughout the world. They utilize
the same modular patch cords and connectors commonly used for telephones.
Once all the RJ11 telephone wire in the premises are Internet ready. Device connected to HomePNA network can
share any high-speed Internet access line-V.90, ISDN, cable, XDSL or wireless modem.
To install the Modem or to access the Internet, you simply plug into your existing telephone jacks just like you would
for a telephone modem or a fax machine. There is no need for special splitters, terminators or filters. In fact, there is
no need to add or modify the home telephone wiring at all.
The 1Mbps Modem uses a frequency division multiplexing approach that enables standard telephone wiring to
simultaneously carry voice, xDSL and home networking signals without any of the services impacting each other.
Signals from the Modem device are centered at 7.5Mhz, with the signal ranging between 5.5Mhz and 9.5Mhz. As
shown in the figure below, this range is well above the frequencies used by voice services (POTS) and digital
subscriber line (xDSL) services. (
