Lucent modem device driver version 5.48 README This update package installs the Microsoft(R) Windows(R) 98 device driver for the Lucent modem that comes preinstalled in your IBM(R) Aptiva(R) computer. This is a V.90 device driver, which enables faster connection speeds over normal phone lines than the 33.6 kilobits-per-second (Kbps) speed that can be achieved with the industry-standard V.34 device drivers. This update package is intended for IBM Aptiva machine types 2137, 2138, 2139, 2153, 2140, 2142, 2161, and 2162. Your Aptiva computer, depending on the model, might have come with a device driver for the 56K modem; this is an upgrade to that device driver.

LIMITATIONS ----------- Although this device driver enables your modem for 56-Kbps connections, you might frequently obtain connections slower than 56 Kbps, for any of the following reasons: o The maximum connection speed that is possible is approximately 53 Kbps, because of United States Federal Communications Commission (FCC) limits on telephone-company power. o The service to which you are connected must support the V.90 or K56flex standard to obtain a high-speed connection. Most of the common online services, such as AOL and CompuServe, support V.90, K56flex, or both. o Excessive electronic interference (noise) on your phone line can reduce your connection speed. o If your telephone company uses more than one analog-to-digital conversion, your connection speed will not exceed 33.6 Kbps. o The V.90 and K56flex standards are available only through service providers with a direct digital link to the telephone company. For example, if you connect your modem to the modem on another computer to play a game, 33.6 Kbps is the maximum connection speed you can obtain. o The high-speed digital data connections enabled by V.90 and K56flex are only for data that your modem is receiving. Data that is transmitted from your modem is limited to a speed of 33.6 Kbps. o Some customers have reported problems using the speaker phone feature of Ring Central after installing this update.
