## ISDN SS Advice Of Charge (AOC)

## Definition

If this service is subscribed to at an outgoing call, currency or charging units are sent to the exchange, depending on the respective network operator. Three different types of how the currency or charging units are sent to the subscriber number are possible (depending on subscription and network operators provision).

#### AOC-D (Advice of Charge during the call)

At call setup to the public network, ASB 150 02 requests for continuous elapsed charging during the call and at the end of the call. This means that the already consumed charging information is always received during the call.

Users of DBC 222, DBC 212, DBC 631 and DBC 223, DBC 213, DBC 662 telephones may read this charging information on their displays during the call.

#### AOC-E (Advice of Charge at the end of the call)

At call setup to the public network ASB 150 02 requests for the charging information to be provided at the end of the call. This means that after termination of the external call the recorded charging information is sent to the respective call meter of the extension.

#### AOC-permanently subscribed

Information on the recorded charges is automatically sent during and at the end of the call, without ASB 150 02 having to request this information from the public network.

## Use

The supplementary service AOC offers the possibility to get an overview of the recorded charges in the public network.
