The TO-CSI identifies services offered on a MSC basis by the serving PLMN operator for all incoming calls on a specific MSC trunk. This CSI shall be stored in the MSC. The contents of the TO-CSI is outside the scope of this specification.
When processing trunk originating calls requiring CAMEL support, the TO-CSI informs the MSC to request instructions from the gsmSSF. The MSC monitors on request the call states (events) and informs the gsmSSF of these states during processing, enabling the gsmSSF to control the execution of the call in the MSC.
Certain basic call events may be visible to the GSM Service Control Function (gsmSCF). The DPs are the points in call at which these events are detected. The DPs for Trunk Originated Calls are described in subclauses 4.4.2.
Dynamic arming/ disarming rules for TO calls are specified in subclause 4.2.1.1. Static arming/ disarming of DP Collected_Info for TO calls shall use the following rules:
  • A DP for trunk originating call is statically armed in the MSC as a result of TO-CSI for the specific MSC trunk.
  • A statically armed DP is disarmed when the TO-CSI that caused the DP to be statically armed is withdrawn from the MSC.
TDP Criteria may be defined for the case when collection of dialled digits has been performed. Criteria may be based on the contents and/ or length of the dialled number, basic service, call type or other information at the discretion of the network operator, however this is outside the scope of this specification.
DP processing rules for TO calls are defined in subclause 4.2.2.
