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.

The actual rate of reception is limited by the quality of your telephone

Currently, 56-Kbps capability is in the receive direction only (from the

The transmit or send direction (from your

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.
