4-2Learning About Your Modem

56K ITU V.90 Standard

If you are able to connect to an ISP using the V.90 standard, the modem will be able to download files at a maximum speed of 56 kilobits per second (Kbps), over standard telephone lines. Download speeds will vary with telephone line conditions.

When using the V.90 standard, download speeds are faster than upload speeds. The maximum download speed is 56 Kbps and the maximum upload speed is

33.6 Kbps. Transmission rates will vary depending on telephone line conditions.

The V.90 and K56flex protocols are designed only to increase the download transmission rate from V.90 or K56flex compliant digital sources. Maximum achievable download transmission rates are currently unknown, may not reach 56 Kbps, and will vary with telephone line conditions.

Understanding Point-to-Point Connections

You can set up your modem to call another modem directly. This is known as a point-to-point connection. During a direct modem-to-modem call, the download and upload speeds are limited to 33.6 Kbps.
