Using the built-in modem features
The built-in modem enables you to send or receive data, faxes, and
voice over the telephone line. This modem uses a digital signal
processor (DSP), and its software can be upgraded, allowing great
flexibility. It supports ITU-T V.90 protocols with data rates of 56
Kbps, and K56flex protocol with data rates of 56 Kbps.
You can use the built-in modem only on a public-switched telephone
network (PSTN). You cannot use a private branch exchange (PBX)
or some other type of digital telephone extension line. If you connect
the built-in modem to a line other than PSTN, an error message
appears, preventing you from using the line. If you are not sure
which kind of phone line you are using, contact your telephone
company.
Attention for use overseas
In many regions, you cannot use the built-in modem function
until IBM has received approval from the proper authorities.
Your built-in modem is a worldwide modem and can be used
in any region where Postal Telegraph and Telephone (PTT)
type approval has been obtained. You can change the
modem setting according to the region where you use the
modem. If the region you want is not on the Region
Selection listing, see http://www.ibm.com/thinkpad on the
Internet, and download the newest Region Selection list.
If you are a non-U.S. user, the parameter for using the
modem is set automatically during the modem installation.
The "Modem Region Selection" window enables you to
change the region name to that of the region in which you
are actually going to use the built-in modem telephony
function. Confirm whether the selection matches the region
name in the Dialing Properties listing.
For more information on the use of the built-in modem in a
specific region, contact the IBM customer support center in that
region.

Using the 56-Kbps modem
To take advantage of your modem's 56-Kbps standard protocol
(ITU-T V.90), you must first make sure that your Internet service
provider (ISP) supports the protocol.
Contact your ISP and determine which 56-Kbps modem protocol it
uses.
If your ISP supports the 56-Kbps standard protocol (ITU-T V.90) or
K56flex technology, your modem uses the same 56-Kbps protocol.
Your modem and your ISP must support the same 56-Kbps protocol,
or your maximum connection speed will be limited to V.34
technology.
Significantly higher Internet modem connection speeds up to 56
Kbps require all-digital transmission connections from your ISP to the
line card in the central office to which your phone line is connected.
The higher speeds at which this modem is capable of operating on a
specific network implementation is only one of many ways to deliver
high-quality voice telephony to customers. Failure of the modem to
operate at high speed should not be reported as a fault, unless
ordinary voice telephone calls are substandard.
In the U.S., current FCC regulations limit the maximum speed for
downstream communication to 56 Kbps. Even though your modem
contains 56-Kbps technology, the connect rate in the receive
direction might be significantly less than 56 Kbps.
Currently, the 56-Kbps capability is in the receive direction only (from
the ISP to your local modem). The transmit or send direction (from
your local modem to the ISP) uses V.34 technology.
Note: 56-Kbps transfer rates are not available in all locations. You
must check with your ISP to determine if your area is capable
of 56-Kbps transfer rates.
