V.90

The TOSHIBA internal modem uses V.90 technology. The modem is capable of
downstream speeds of 56Kbps (kilobits per second) when connected to an Internet
service provider that supports V.90. 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
28-50Kbps 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 host
modem is connected to another. The TOSHIBA Internal modem will select
automatically V.34 if the remote modem lacks V.90 capability or if a
combination of network and/or phone line conditions prevent V.90
connection.
