An internal modem provides capability for data
and fax communication. It supports V.90 (V.92).
The speed of data transfer and fax depends on
analog telephone line conditions. It has a modem
jack for connecting to a telephone line. Both of
V.90 and V.92 are supported only in USA,
Canada, UK, France, Germany and Australia.
Only V.90 is available in other regions.
The computer has built-in support for Ethernet
LAN (10 megabits per second, 10BASE-T) and
Fast Ethernet LAN (100 megabits per second,
100BASE-TX).
Some computers in this series are equipped with
a Wireless LAN mini-PCI card that is compatible
with other LAN systems based on Direct
Sequence Spread Spectrum/Orthogonal
