Learning 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.
