Abstract

A method and apparatus (Fig. 3A) for wideband voice and optional data conferencing over a telecommunications network channel between at least two wideband communications devices (PC 302, 322 and Video Display 330, 304). An exemplary method comprises establishing an audio link, verifying wideband capability between the at least two wideband communications devices, training modems of the at least two wideband communications device to line conditions, and adjusting the telecommunications connection line conditions between the communications devices. Once a wideband connection has been established, audio and data may be simultaneously exchanged.
