• ISDN AOC-E, which is based on the AOC supplementary service for ISDN (ETS 300 182, August

1993).

•Display AOC-E, which uses the ISDN Display Information Element, as defined in ITU-T Q.931 to con-

vey textual AOC information.

•CEPT AOC-E, which uses the CEPT Charge Advice Information Element.

2. This feature supports only Advice of Charge at the end of the call (AOC-E). If Advice of Charge during the

3. The 2BRI or the PRI blade is required.

4. Charge information control for each country is speciﬁed by the ISDN protocol type setting in system data

Call charge=UT x Unit rate

UT (charging unit): UT sent from AP

Unit rate: Rate specified by system data programming

6. The unit rate can be set to two places of decimals. When the unit rate has three or more decimal places, it is

required to round up or truncate the number to two decimal places and set that value. The integral part of

unit rate can be set to maximum two digits.

7. If AOC information is not sent due to the cause of network, call charge information is not displayed.
