Event Notification Capabilities
6-6 Issue 7 May 1998
Event Notification Cancel
This capability enables the adjunct to cancel any notification request (for all calls)
for a given domain only for the association that received the request.
Information Flow
ECS always accepts the request. If the request is not understood by ECS or is
received over a non-Event Notification association, ECS aborts the association.
See Chapter 3, ‘‘Event Reporting and U-Abort Capabilities’’ for more information
regarding the U-Abort capability.
Event Notification Cancel Parameters
None for this capability.
ACK (Positive Acknowledgement) Parameters
No parameters are contained in the acknowledgement for this capability.
Denial (NAK) Cause
ECS issues the following reason as the cause for not executing the request.
■ Invalid association (CS0/81)
The association does not exist.
Protocol Error (NAK) Cause
ECS issues the following cause for generating a protocol processing error:
■ Protocol error (CS0/111)

calls in progress cease over this particular association.
