For Windows 98, Windows 95 and Windows NT
When you start Windows, the ThinkPad modem automatically starts
and is ready for use.
Using the 56-Kbps Modem
To take advantage of your modem's 56-Kbps U.S. Robotics 56k
Technology**, you must first make sure that your Internet service
provider (ISP) supports a 56-Kbps modem protocol.
1
Contact your ISP and determine which 56-Kbps modem
protocol it uses.
2
Determine which 56-Kbps modem protocol your modem
supports. To view your modem's supported protocol, do the
following:
a) Click on Start, move the cursor to Programs, and then
click on ThinkPad Modem.
b) Choose Options from the “Modem Status” window; then
choose Settings.
The available transfer speeds are displayed. The 56-Kbps
protocol your modem supports is listed in parentheses
following the 56-Kbps transfer setting. Be sure to select
the 56-Kbps transfer setting to use it.
Your modem and your ISP must support the same 56-Kbps protocol,
or your maximum connection speed is 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.
