Server-to-Client Data Rates
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.
