Home PNA network adapter
Some models might have a Home Phoneline Network Alliance network adapter
with an integrated V.90 modem. In addition to its modem function, this adapter
enables you to use the telephone wiring in your home for peer-to-peer networking.
To use the Home PNA Network adapter, you must install the Intel AnyPoint
software from the Software Selections CD. Each computer on the home PNA
network must have a PNA network adapter and the associated software installed.
For information about using the PNA network adapter or the AnyPoint software,
refer to the AnyPoint documentation (provided with models that come with PNA
network adapters only).
