More information
You can also establish a class of restriction with Forced Entry of Account Codes 
set to 
y
, and assign this COR to trunks or other facilities that you want to restrict. 
With this method, all users with this COR must enter account codes before 
making any outgoing trunk calls. See 
‘‘Class of Restriction’’ on page 520
 for 
more information. 
Receiving call-charge information
DEFINITY ECS provides two ways to receive information from the public 
network about the cost of calls. Note that this service is not offered by the public 
network in some countries, including the US.
Advice of Charge (for ISDN trunks) collects charge information from the 
public network for each outgoing call. Charge advice is a number 
representing the cost of a call; it may be recorded as either a charging or 
currency unit.
Periodic Pulse Metering (for non-ISDN trunks) Periodic Pulse Metering 
(PPM) accumulates pulses transmitted from the public network at periodic 
intervals during an outgoing trunk call. At the end of the call, the number of 
pulses collected is the basis for determining charges.
Before you start
You need to request either AOC or PPM service from your network provider. In 
some areas, your choice may be limited. Your Lucent Technologies representative 
can help you determine the type of service you need.
NOTE:
This service is not offered by the public network in some countries, 
including the US.
Collecting call charge information over ISDN
In this example, we administer the system to provide Advice of Charge over an 
existing ISDN trunk group, at the end of a call. This information will appear on 
CDR reports.
