Call Detail Records (CDRs)

You can configure the Summit WM Controller to generate Call Detail Records (CDRs), which contain
usage information about each wireless session per WM-AD. For more information on how to configure
the Summit WM Controller to generate CDRs, refer to
page 179.
CDRs are located in a CDR directory on the Summit WM Controller. To access the CDR file, you must
first back up the file on the local drive, and then upload it to a remote server. After the CDR file is
uploaded to a remote server, you can work with the file to view CDRs or import the records to a
reporting tool.
You can back up and upload the file on the remote server either via the Summit WM GUI or CLI.

CDR files

CDRs are written to a file on the Summit WM Controller. The filename is based on the creation time of
the CDR file with the following format: YYYYMMDDhhmmss.<ext>
YYYY - Four digit year
MM - Two digit month, padded with a leading zero if the month number is less than 10
DD - Two digit day of the month, padded with a leading zero if the day number is less than 10
hh - Two digit hour, padded with a leading zero if the hour number is less than 10
mm - Two digit minute, padded with a leading zero if the minute number is less than 10
ss - Two digit second, padded with a leading zero if the second number is less than 10
<ext> - File extension, either .work or .dat

CDR file types

The following two types of CDR files exist in the CDR directory on the Summit WM200/2000
Controller:
.work - This file is the active file that is being updated by the accounting system. The file is closed
and renamed with the .dat extension when it attains its maximum size - 16 MB - or it has been open
for the maximum allowed duration - 12 hours. You can back up and copy .work file from the
Summit WM Controller to a remote server.
.dat - This file is the inactive file that contains the archived account records. You can back up and
copy the .dat file from the Summit WM Controller to a remote server.
NOTE
The CDR directory on the Summit WM Controller only has two files - a .work file and a .dat file. When the .work file
attains its maximum size of 16 MB, or it has been open for 12 hours, it is saved as a .dat file. This new .dat file
overwrites the existing .dat file. If you want to copy the existing .dat file, you must do so before it is overwritten by
the new .dat file.
