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 applicants suppoorted by the operating system.
V.34 ITU (Intrtnational 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.
