Call Charge Information
DEFINITY ECS provides two ways to know the approximate charge for calls
made on outgoing trunks:
■ Advice of Charge — for ISDN trunks
Advice of Charge (AOC) collects charge information from the public
network for each outgoing call. Charge advice is a number representing the
cost of a call; it is 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.
Call-charge information helps you to account for the cost of outgoing calls
without waiting for the next bill from your network provider. This is especially
important in countries where telephone bills are not itemized. You can also use
this information to let employees know the cost of their phone calls, and so
encourage them to help manage the company’s telecommunications expenses.
Note, however, that you cannot necessarily use this information to dispute
telephone bills with the network provider.
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.
Detailed description
The availability of AOC and PPM varies from one country to the next. In some
countries, AOC information is received automatically for each call. In others, the
system must request AOC information for each call.
In some countries, the public network sends call-charge information only at the
end of a call. In others, the public network sends information during a call as well.
PPM is available over the following trunk types:
■ CO
■ DIOD
■ FX
