Event Reporting and U-Abort Capabilities

U-ABORT

This capability is used by both the adjunct and the ECS to inform the other that an association is abnormally ending. It is shown here but may be used in all capability groups at any time during an association.

Information Flow

The U-Abort ends the association and no response is possible.

U-Abort Parameters

The ECS may issue one of the following reasons as the cause for ending the association:

Error in vector/host not responding (CS0/102)

Either the vector is incorrectly programmed or the host has not responded to the route request in a timely manner.

Protocol error (CS0/111)

The Q.932 protocol has been violated.

Call merge attempt failed (CS0/98)

An attempt was made to merge two calls that were not controlled.

Error in association (CS3/87)

The ECS software audits found something wrong and the ECS is taking steps to correct the association.

NOTE:

For more information regarding protocol errors and a complete list of reason codes (cause values), see the DEFINITY Enterprise Communications Server CallVisor ASAI Protocol Reference, 555-230-221.
