METHOD AND APPARATUS FOR WIDEBAND CONFERENCING
First Claim
1. A method for wideband conferencing over a narrowband Plain Old Telephone System (POTS) connection from a first device, comprising:
- establishing one narrowband analog audio connection to a second device over a POTS connection;
verifying that the second device is wideband capable;
obtaining a first wideband digital audio signal at the first device;
transmitting the first wideband digital audio signal over the narrowband audio connection from the first device to the second device; and
receiving a second wideband digital audio signal from the second device and reproducing audio from the received second wideband digital audio signal at the first device.

Abstract
A method and apparatus for wideband voice and optional data conferencing over a telecommunications network channel between at least two wideband communications devices. 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.

22. A device capable of conducting a wideband conference over a narrowband analog Plain Old Telephone System (POTS) connection, comprising:
-
a microphone;
a codec coupled to the microphone;
a modem coupled to the codec and for coupling to the analog POTS connection;
a controller coupled to the codec and the modem; and
an audio reproducing device coupled to the codec;
wherein the codec is operative to convert analog audio signals to wideband digital signals and wideband digital signals to analog audio signals;
wherein the modem is operative to modulate and demodulate digital signals exchanged through the POTS connection; and
wherein the controller is operative to verify a second communication device connected over the POTS connection is wideband capable. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
