Christian,
I agree that the servicechange forced indicates that something is wrong it's just that the actual connections are not necessarily lost. This would occur when the problem is caused by a local equipment failure as opposed to a network failure.
Instead of deleting the text may I suggest changing the text to read: "and any established connections associated with them may be lost".
Regards, Paul

G'Day Paul,
I think that the servicechange forced really does indicate that something is wrong so the connections may well be lost. So I'm a little hesitant removing this text. It is correct that out-of-service indicates the termination cannot be used for traffic and they may well be because the termination has failed and lost any connection.
I've forwarded this to the Megaco list for comment also.
Regards, Christian

Christian,
Proposed change to section 7.2.8 ServiceChange, 2) Forced: delete the text "and any established connections associated with them were lost" so that the paragraph now reads:
- Forced - indicates that the specified Terminations were taken out of
service. The MGC is responsible for cleaning up the context (if any) with which the failed termination is associated. At a minimum the termination shall be subtracted from the context. The termination serviceState should be "out of service".
Explanation: it is possible for the connection to still exist even if a termination is out of service. It does not matter if the connection associated with the termination is lost or not it only matters whether the termination is in service or out of service. From section 7.1.5 Termination State Descriptor: "The state "out of service" indiates that the termination cannot be used for traffic."
Regards, Paul

G'Day all,
I have come up with an interim version of the H.248 Implementors' Guide Additions v5. It contains additional correction to ones reviewed at the SG16 Launceston meeting.
It can be found at: ftp://standard.pictel.com/avc-site/Incoming/ filenames: TD-xxx_H248_Implementors_Additions_v5.doc TD-xxx_H248_Implementors_Additions_v5.pdf
Please check it for correctness and that it contains the points discussed on the list. There were also some corrections added that were not discussed on the list. If you have an issue please propose a solution giving the wording that you would like to see. As mentioned in the introduction this document is liable to change until final approval.
v4 was my own edition and was not published to any external network/list so please don't look for it.
Let the editor bashing begin.
Cheers, Christian
