Title: C79DMMST CreationDate: 07/16/97 13:09:22 2-42 2 Determine which 56 Kbps modem protocol your modem supports. To view your modem's supported protocol, do the following: a) Click on the Start button, and select Programs and Modem (or Modem & Audio). b) Click on Modem. c) 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. If no 56 Kbps transfer setting is listed, your modem's 56 Kbps technology is not currently enabled. Refer to the user's guide supplement for details. 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 actual rate of reception is limited by the quality of your telephone line, which may vary from location to location. In the U.S., current FCC regulations limit the maximum speed for downstream communication to 53 Kbps. Even though your modem contains 56 Kbps technology, connect rate in the receive direction might be significantly less than 56 Kbps. Currently, 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 or countries. You must check with your ISP to determine if your area is capable of 56 Kbps transfer rates.

Programs
and
Modem
(or
Modem & Audio
).
b) Click on

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.
If no 56 Kbps transfer setting is listed, your modem's 56
Kbps technology is not currently enabled.
Refer to the
user's guide supplement for details.
Your modem and your ISP must support the same 56 Kbps protocol,
or your maximum connection speed will be limited to V.34
technology.

Kbps require all-digital transmission connections from your ISP to the
