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.
Chapter 2. Using the features of your computer 11

Setting the modem

To use the built-in modem, connect one end of the telephone cable to the modem connector; then connect the other end to the telephone outlet on the wall.
Note: To use a DOS modem application in the Windows 95 or
Windows 98 DOS box, disable the infrared port. When you start Windows, the modem automatically starts and is
ready for use. To use the built-in modem outside the region where you purchased
the computer, you must change the region name.

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.

Using the Auto Answer feature

If you use a modem communication software program, your modem might need to be set for your computer answer calls from another computer automatically.
Your modem communication software determines how the modem operates with Auto Answer. Some fax programs do not require you to type an AT command to turn Auto Answer on or off. For specific instructions, see the user's guide that came with the communication software.
To start the Auto Answer feature from your communication software, use the command ATS=n. This command tells the modem to answer a call after a certain number of rings. To set the number of rings, replace n with any number from 1 to 255.
Auto Answer
1
. The Auto Answer feature lets
If you do not have a voice modem, turn Auto Answer off when you are not using your modem. Otherwise, callers will be greeted with the modem tone. To turn Auto Answer off, use the command ATS = .
In some communication software programs, you might need to select the “Auto Answer On” or “Auto Answer Off” option to turn off the Auto Answer feature.
Note: If you are using Auto Answer with a fax software program,
setting a high number of rings enables you to answer the telephone before the fax modem answers.

Viewing a DVD movie

Note
You need a DVD-ROM drive and the ThinkPad 570 UltraBase, available as an option, to view a DVD movie.
If you want to view a DVD movie on your computer, you need to set the DVD region code. You can set the region code when you start DVD Express for the first time.
Notes:
1. The DVD movie player program is supported by Windows 98 and Windows 95 OSR2.0 or later version.
2. Some DVD movies might not play in your computer. If it is possible to play another DVD movie in your computer, the problem is not with your computer. Check with the DVD vendor whether there is a problem with the DVD content.
3. You need to disable system timers when viewing a DVD movie to avoid screen blanking.
DVD regional codes
Regional coding is part of the protection strategy for DVD content. The world is divided into six regions. Specific content can be viewed only in a specific region. For example, Region 1 (U.S. and Canada) content should be viewed only in Region 1. The DVD Movie Player Program application is also region-specific.
You must select a region to play DVD content. After you select the region, you can play content only for that region. Be sure to select your correct region.
An incorrect region code setting causes your computer to hang; you can recover your computer only with the Recovery CD.
18 IBM ThinkPad 570 Online Book
Attention
Make sure the first DVD content you play is from the appropriate region. You can verify the region code of the content by looking at the region code symbol on the back of the content packaging. If the first DVD you play is from a region other than the region you selected, your system will no longer play DVD content. Recover your system using the Recovery CD.
To set the region code, do as follows:
1
Click Start, move the cursor to Programs and Mediamatics DVD Express, and then click Mediamatics DVD Player.
The “Select DVD Region” window appears.
