RPCI/DIU Data Speed (Baud Rate) 
DIUs pass data at a baud rate of up to 19,200 bits per second (bps), if the call was 
established by manually dialing from a data telephone. If the call was established with 
AT commands from a PC or terminal, the DIU passes data at up to 9600 bps. The baud 
rate of a DIU is transparent when originating calls with the data telephone or when 
receiving data calls, manually and automatically. When...
