Rpci/Diu Data Speed (Baud Rate); Rpci/Diu Default Communication Parameters - Toshiba Strata DK User Manual

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
