This device is normally a PC with a V.24 interface on which the data received is analysed.
The CDRC data can be output in two different formats:
Compressed format for PC or call charge computer
All data is output (incl. project code) excluding separating blanks, header line and page feed.
Call charge pulses are also output.
Uncompressed format for printers
All data (apart from project code) is output separated by blanks, with header line (in several
languages) and page feed. The call charge amount is output.
The following rules apply to the line format:
The control characters CR (carriage return) and LF (line feed) are transmitted at the end of each
data record.
Data not supplied and unused fields are replaced by or filled with space characters.
In compressed format, the data is output consecutively. A form feed (FF) is not executed.
With long format, a one-line header followed by a blank line is output on each page. After 62
lines have been printed, a form feed is executed automatically.
The following data is output:
Date (at end of call), 8 characters
Time (at end of call), 8 characters
Number of seized trunk line, 3 characters
Internal extension number (max. 6 digits)
Call duration, 5 characters
External extension number (max. 25 digits if transferred)
