Communications
Modem
All notebook models include an RJ-11 telephone jack, and some
models ship with a preinstalled modem. A modem cable with
RJ-11 connectors at each end is included with select models.
You need a modem cable to connect a modem. If your model did
not include a modem cable, a modem cable can be purchased
from most computer or electronics retailers.
If you purchased a notebook with an internal modem in a country
where RJ-11 telephone jacks are not standard, a country-specific
modem adapter is included with the notebook.
An internal modem supports:
■ All applications supported by the operating system.
■ V.34 ITU (International Telecommunications Union) analog
modem recommendations for speeds up to 33.6 Kbps.
■ V.44 data compression algorithm.
■ V.90/V.92 ITU digital/analog modem pair recommendations
for speeds up to 56 Kbps.
The digital/analog modem pair rates allow faster downloads
only from compliant digital sources. Maximum achievable
download rates are currently unknown, may not reach
56 Kbps, and will vary with line conditions. Maximum
achievable upload rates are limited to 48 Kbps, may not reach
48 Kbps, and will vary with line conditions.
