Event Reporting and U-Abort Capabilities

Cut-Through Event Report

The Cut-Through Event Report is sent when an ISDN PROGress message has been received for a call using the ISDN-PRI facilities. The ECS maps the PROGress message to a Cut-Through Event Report.

An ISDN-PRI network may send the ECS a PROGress message for several reasons that are contained in the Progress Indicator (within the PROGress message). The ECS forwards the PROGress indicator to the adjunct in the Cut-Through Event Report.

The ECS may receive multiple PROGress messages for any given call; each maps into a Cut-Through Event Report for the call.

This event applies to all monitored or controlled calls except switch-classified.

This event is only sent to the destination party as follows: When a monitored or controlled call moves to an off-ECS destination and the PROGress message is received from the ISDN-PRI facility network.

ISDN Progress Messages

Starting with R5: Since the German 1TR6 (National ISDN) Network does not support ISDN-PRI PROGRESS messages, no Cut-Through Event Report will be sent to an adjunct on ASAI.

Starting with R5: As the French VN4 network only uses the ISDN-PRI PROGRESS messages for interworking, a PROGRESS Indicator 1 message may be sent to DEFINITY ECS. Progress Indicator 1 describes the call as not being end-to-end ISDN and that further call progress information is available in-band. It is also possible for a PROGRESS message to be sent to DEFINITY ECS without a Progress Indicator present.

Cut-Through Report Items

The following is a list of items provided with this report:

call_id

This ECS-assigned call identifier is used to associate event reports to calls and identify a call the adjunct wants to control. The call identifier is unique within the ECS.
