Station Message Detail Recording (SMDR) provides a record of the system’s outside calls. Typically, the record outputs to a customer-provided printer or PC.

  • The default DSX serial port baud rate is 38,400. The data format is fixed at 8 data bits, no parity, with one stop bit (8N1).
  • To connect to the DSX serial port:
    - Use adaptor P/N 1091014 to connect to the 9-pin printer serial port
    - Run a standard 6-conductor line cord from the adaptor DSX serial port.
    - Note that SMDR does not buffer records when the printer is disconnected.
