Managing CDR data
CDR provides three methods to manage data:
• Pull Transfer
• Push Transfer
• real-time data
Pull Transfer
With Pull Transfer, you can download Call Detail Recording data files from the BCM 4.0 to any
PC on your network that has a pull application installed. You configure the data transfer
parameters on the PC to download the CDR data files. The advantage of the Pull Transfer is that
the PC determines the rate at which the data files are transferred, so it cannot easily be overloaded
with transfer information. You can use the Pull Transfer to transfer Call Detail Recording data
files from any number of BCM 4.0s or other BCMs, but it is most beneficial when you are
transferring from a large number of systems.
There is a sample CDR Pull Client provided on the BCM web page. For details on installing and
using CDR Pull, see “Using CDR Pull Transfer” on page 25.
Push Transfer
With Push Transfer, the system sends the CDR data files to a central server. The advantage of the
Push Transfer is that you configure the data transfer parameters on the Element Manager. No
additional applications are required. You can use the Push Transfer to send Call Detail Recording
data files from any number of BCM 4.0 systems, but it is most beneficial when you are transferring
from a smaller number of systems.
Note: The CDR Pull Client is a sample application only. The CDR Pull Client
allows you to test the CDR pull capability of the BCM. A developer’s toolkit is
available to build a CDR client to meet your specific needs. Refer to the Nortel
Developer Partner Program for details on the BCM CDR toolkit or check with
your CDR application vendor for availability of this functionality in their
software.
Note: You can use the CDR Pull Client to pull files from any BCM system.
!
Security note: The Data File Pull Transfer uses a secure SSL interface to transfer the
Call Detail Recording data files. The Data File Push Transfer does not use a secure
interface to transfer the Call Detail Recording data files.
