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.
V.90 mode
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.
