Appendix C-CDR Fields - Unformatted File
Polycom, Inc. C-3
Event Records
The event records, that is, all records in the unformatted file except the first record, contain
standard fields, such as the event type code and the time stamp, followed by fields that are
event specific.
The event fields are separated by commas. Two consecutive commas with nothing between
them (,,), or a comma followed immediately by a semi-colon (,;), indicates an empty field, as
in the example below:
Standard Event Record Fields
All event records start with the following fields:
• The CDR event type code. For a list of event type codes and descriptions, refer to
Table C-2, “CDR Event Types,” on page C-4.
• The event date.
• The event time.
• The structure length. This field is required for compatibility purposes, and always
contains the value 0.
GMT Offset The time zone difference between Greenwich and the MCU’s physical
location in hours and minutes.
Together with the GMT Offset Sign field the GMT Offset field is used to
define the MCU local time. For example, if the GMT Offset Sign is 0 and
GMT Offset is 3 hours then the time zone of the MCU’s physical location
is -3, which will be subtracted from the GMT time to determine the local
time. However, if the GMT Offset Sign is 1 and GMT Offset is 4 hours
then the time zone of the MCU’s physical location is +4, which will be
added to the GMT time to determine the local time.
File Retrieved Indicates if the file has been retrieved and saved to a formatted file, as
follows:
0 - No
1 - Yes
