ASAI and Domain Control
Issue 7 May 1998
5-29
Third Party Relinquish Control
The adjunct uses this terminating capability to end a Domain Control association.
The ECS continues to process all calls at the domain-controlled station or split or
EAS skill normally. Calls present at the domain-controlled station or split or EAS
skill are not affected by this capability.
Information Flow
The adjunct expects a response to its request.
The ECS always ends a domain control association and acknowledges the
request.
Issuing this capability terminates the Domain Control association. Thus, all event
reporting on the association ends.
This capability may be issued any time.
Third Party Relinquish Control Parameters
None for this capability.
ACK (Positive Acknowledgement) Parameters
No parameters are contained in the acknowledgement for this capability.
Denial (NAK) Cause
None for this capability.
Protocol Error (NAK) Cause
The ECS issues the following cause for generating a protocol processing error:
■ Protocol error (CS0/111)
The Q.932 protocol has been violated or the capability invoked is not
consistent with this association. For example, invoking a Third Party
Domain Control Request over a Call Control association is inconsistent.
