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 originating data calls with AT 
commands from a PC or terminal, the DIU speed is the same as the rate of the first AT 
command. When answering data calls with the ATA command string, the DIU baud 
rate is the same as the command string; the AT command baud rate is determined by 
software running the terminal or PC.
RPCI/DIU Default Communication Parameters
Default parameters for the DIUs are shown below; however, they are transparent or 
changed by the first AT commands issued, as described above. A DIU assumes these 
default parameters when power is initially applied to it, or after the modular cord is 
disconnected and then reconnected.
©Baud rate: 1200 bps
©Data bits: 8 bits
©Parity: none
©Stop bits: 1 stop bit
