Abstract
An inband signaling modem receives digital user data for transmission to a remote location, via wireless and land line telecommunication networks. The modem converts the user data into audio tones for transmission, and encodes the audio tones into digital form suitable for transmission through a voice channel call session of a digital wireless network. After establishing a voice channel call session on a digital wireless network, the modem disables any echo cancellation or echo suppression means that may be encountered in the voice channel call session; and then transmits the user data audio tones. Preferably, disabling the echo cancellation or echo suppression means comprises transmitting a predetermined tone in the voice channel call session. Further, the modem preferably repeats the tone, to again disable echo cancellation or echo suppression means, at the beginning of each data burst during the call session.
