ABSTRACT:
A communication system and method for transmitting and receiving teletype information in a vehicle (20). The communication system (22) includes an external interface (24) and a communication control unit (26). The external interface (24), embedded in the vehicle (20), is capable of receiving a first set of teletype signals from a portable TTY terminal (50) and capable of sending a second set of teletype signal to the portable TTY terminal (50). The communication control unit (26), also embedded in the vehicle (20), is connected to the external interface (24) and comprises a controller (36) and a transceiver (34). The transceiver (34) is capable of transmitting messages over a wireless communication link (A) that contain information from the first set of teletype signals. The transceiver (34) is also capable of receiving messages over the wireless communication link (A) that contain information for the second set of teletype signals.
