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. 14 IBM ThinkPad 770X Online Book
