18.1. AOCC - Request charges per line for remote station 
Feature:
Call Data Recording Enhancements CDRe (enhancement of existing call data recording
for call
data recording)
Function:
The AOCC parameter is used to set the sending or suppression of the "call charge
details per line" request to the remote station because, for example, no charges are
recorded in the user's own system.
AOCC set: When a connection is being set up or when a consultation connection is
being transferred, the operation call "charge details per line" is sent to the remote
station if the requesting partner device has entered CDRSTN class of service.
AOCC not set: The "call charge details per line" operation is not sent to the remote
station either when a connection is set up or during transfer. The partner node does
not
send ongoing charge data.
IMPORTANT:
It must be set on CORNET-NQ trunks. It may not be set on Cornet V3.3
trunks.
IMPORTANT:
In the case of external systems with ECMA/QSIG it is necessary to check
whether the parameter is correctly interpreted in the remote station. Display information
is
lost if the interpretation is incorrect. The AOCC parameter may not be set with other
protocols, such as DSS1, DPNSS1 (Digital Private Network Signaling System No. 1),
DASS2
(Digital Access Signaling System No 2, protocol for use as trunk interface in Great
Britain)
because the remote station cannot interpret the protocol signals generated by it,
so that
the display information is incorrectly deactivated in the OpenScape 4000.
AMO Interrelationships:
COSSU: CDRSTN ... Immediate charge data display on the station if a display is
available
IMPORTANT:
The AMOs TACSU, TSCSU and TDCSU can also be used to assign a COS with
CDRSTN authorizations to a trunk whose protocol cannot transfer the classmarks.
