V.90 speeds when accessing a V.90 or V.92 server (actual speed
depends on server capabilities and line conditions) *Though these
modems are capable of 56K bps download performance, line
impairments, public telephone infrastructure and other external
technological factors currently prevent maximum 56K bps
connections.
Up to 50Kbps when accessing a V.92 server (actual speed depends
on server capabilities and line conditions); otherwise, the same as
client-to-client data lines.
