V.90/V.92
The TOSHIBA internal modem uses V.90 technology. The modem is capable of
downstream speeds of 56Kbps (kilobits per second) when connected to an Inter-
net service provider that supports V.90/V.92. As with any modem, the actual
throughput (speed of data transfer) depends on analog telephone line conditions,
which can vary considerably. Therefore, many users will experience throughput
in the range of 32-44Kbps under normal telephone line conditions. Upstream
data flows at the V.34 rate.
NOTE: V.90 rates can be achieved only when one V.90 capable modem
is connected to another. The TOSHIBA Internal modem will select auto-
matically V.34 if the remote modem lacks V.90 capability or if a combi-
nation of network and/or phone line conditions prevent V.90 connection.
