Abstract
A communication apparatus includes a mechanism for reducing loss of text telephone information during normal traffic channel preempting. The communication apparatus includes a transmitter that may generate a signal including a plurality of text telephone symbols for transmission via a voice channel. The transmitter may receive a notification that indicates information transmitted via the voice channel will be replaced by control information. In response to receiving the notification, the transmitter may further selectively prevent at least a portion of the plurality of text telephone symbols from being provided for transmission.
