CALL DETAILS RECORDER
CDR Memory is used to store call details for each exchange line until the printer is ready for data.
Printer Interface sends serial data to the printer in RS-232C format at 150, 300, 600, 1200, 2400 or
4800 baud.
Switches are used to set the baud rate for the printer and to select various printout options.
Jack Assembly provides connection between the CDR board and a standard RS-232C cable.
