Using an Internal Modem

Your notebook has an internal modem, an RJ-11 telephone jack,
preinstalled modem drivers, and a modem cable. The internal
modem:

Supports applications running under Microsoft Windows 98,

■

Windows 2000 Professional, Windows XP Home, and
Windows XP Professional operating systems.

Supports V.34 ITU (International Telecommunications

■

Union) analog modem recommendations for speeds up to

33.6 Kbps. Supports V.44 data compression algorithm.

Supports 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 31.2 Kbps, may not
reach 31.2 Kbps, and will vary with line conditions.

Uses a universal Direct Access Arrangement (DAA) that

■

supports multiple countries. An adapter may be required to
connect the modem to the standard telephone jack in some
countries.

Does not support the modem pass-through connection

■

available on some optional port replicators.

Connecting the Modem Cable

Using the RJ-11 Cable

The modem cable may have noise suppression circuity that
prevents interference with TV and radio reception. The modem
cable must be connected to an analog telephone line.

CAUTION: Jacks for digital PBX systems may resemble analog

telephone jacks, but are not compatible with the modem.

1. If the modem cable has noise suppression circuitry 1, orient
the circuitry end of the cable toward the computer.

2. Plug the cable into the RJ-11 telephone jack

Using an Internal Modem

Using a Country-Specific Modem Cable Adapter

Software for the internal modem supports multiple countries, but
telephone jacks vary by country. To use the modem and the RJ-11
cable outside the country in which you purchased the notebook,
you must obtain a country-specific modem adapter and define
your location in Dialing Properties.

To connect the modem to an analog telephone line that does not
have an RJ-11 telephone jack:

1. If the modem cable has noise suppression circuitry
the circuitry end of the cable toward the notebook.

2. Plug the modem cable into the RJ-11 telephone jack

Using an Internal Modem

Adding New Locations When Travelling

The internal modem is configured to meet only the operating
standards in the country where you purchased the notebook.
When travelling internationally, you can add new location
configurations that comply with standards in other countries.

CAUTION: Do not delete your current modem country settings. To

Ä

enable modem use in other countries while preserving your home
country configuration, add a new configuration for each location in
which you will use the modem.

The drop-down lists described below may include countries not
supported by the modem. Unless you select a supported country,
the country selection will default to USA or UK.

CAUTION: Selecting a country other than the one in which it is

Ä

located may cause your modem to be configured in a way that
violates the telecommunications regulations/laws of that country.
In addition, your modem may not function properly if the correct
country selection is not made.

To add a new country location, follow these steps:

Windows 98:

1. Select Start > Settings > Control Panel.

2. Double-click the Modems icon > General tab > Select your
modem > Dialing Properties.

Solving Travel Connection Problems

If you experience connection problems while using the modem
outside your home country, the following suggestions may help:

Check the telephone line type

■

The modem requires an analog, not a digital, telephone line.
A line described as a PBX line is usually a digital line. A
telephone line described as a data line, fax machine line,
modem line, or standard telephone line, is probably an
analog line.
