Page 150 of 1814 Advice of Charge553-2901-301 Standard 9.00 January 2002• The Advice of Charge information is not transported between aMeridian 1 to Meridian 1 connection. Therefore, if a tandem call is madefrom one Meridian 1 PBX to another Meridian 1 PBX, and then to aCentral Office, the originator’s display is not updated with the chargeinformation. However, the charge is printed in the CDR record at theswitch that made the connection to the Central Office.• Charging information received on incoming calls, as may happen forreverse charging, is not supported. The existing error indication is givenif an incoming call is received. This does not happen in Australia becausethe AOC information must be requested for each call and the Meridian 1does not support requesting AOC information for incoming calls.Feature interactionsThe following feature interactions apply to the Advice of Charge service, forthe AXE-10 Australia, INS1500 (Japan D70), Numeris, SwissNet,EuroISDN, and 1TR6 Central Office interfaces.Attendant CallsIf the attendant originates an external call using an ISDN CO trunk providingAOC, the call charging information received from the network will be savedin the trunk’s temporary meter at the end of the call. The contents of thetemporary meter will be added to the contents of the attendant meter for thecustomer.If the attendant is the last controlling party (i.e., does not release the call), whogets charged depends on who initiated the call. If the attendant made the callwith a party on the source, it is the source who gets charged. If the attendantmade the chargeable call and then dialed an internal party (station or TIEtrunk) on the destination side of the loop without releasing, the attendant getscharged.Attendant operation of metered callsIf an attendant desires billing information immediately upon the completionof a long distance call, this call can be flagged as a metered call. When ametered call is terminated, the attendant is recalled and the calculated chargefor this call is displayed on the console.
