Collecting billing information
Collecting information about calls
Call Detail Recording (CDR) collects detailed information about all incoming and 
outgoing calls on specified trunk groups. If you use intraswitch CDR, you can also 
collect information about calls between designated extensions on the switch. 
DEFINITY ECS sends this information to a printer or to some other CDR output 
device that collects call records and that may also provide reports. 
You can have a call accounting system directly connected to your switch. If you 
are recording call details from several switches, the switch may send the records 
to a collection device for storage. A system called a poller may then take these 
records and send them to the call accounting system. The call accounting system 
sorts them, and produces reports that you can use to compute call costs, allocate 
charges, analyze calling patterns, detect unauthorized calls, and keep track of 
unnecessary calls.
Before you start
The call accounting system that you use may be sold by Lucent, or it may come 
from a different vendor. You need to know how your call accounting system is set 
up, what type of call accounting system or call detail recording unit you are using, 
and how it is connected to the switch. You also need to know the record format 
that your call accounting system requires.
