RE: Access To Megaco Documents

I see a typo in the URL I gave -- not sure how, since it was a
cut-and-paste.  Anyway, the right URL is
ftp://ftp <at> standards.nortelnetworks.com/megaco/docs/

Tom,

The URL does not seem to work. Is this a new server? 

Because the URL used to be:

ftp://standards.nortelnetworks.com/megaco/docs/

You have mentioned below that the URL is

ftp://ftp <at> stadards.nortelnetworks.com/megaco/docs/

Anyways, I have tried both. No luck.

Thanks,
Bala

G'Day Tom,

I don't think 1 information element is such a burden. Irrespective of how its
coded it will support the same functionality and be used in the legacy
environment.

Mode in LocalControl ***

Hello,
In the 3015 RFC there is an example of sending the Mode to both physical
and ephemeral terminations?
What should be done if only one of them receives a "Mode" parameter?
What should be done if there are two different Modes for the physical and
ephemeral terminations?

H.248 Renumbering

I mentioned in the past that the ITU-T is renumbering H.248 and its annexes.
The correspondence between old and new numbering will be made clear on the
ITU-T web page, but I'll show the table here for your general information:

Previous numbering	New numbering	Title

H.248 (Main text 	      H.248.1 (06/2000)	Gateway control protocol
+ Annexes A to E)

Note: This version 1 of H.248.1 is considered to be that of H.248 (Main text
+ Annexes A to E) of 06/2000, updated with an "Amd1 to H.248.1" of 02/2002
which brings changes, clarifications and corrections but no new
functionality. Available for sale but superseded by H.248.1 of 02/2002

	                  H.248.1 (02/2002)	Gateway control protocol
Note: This version 2 of H.248 (Main text + Annexes A to E) has additional
functionality compared to version 1 of 06/2000.

"Error tone" specification

Can anyone say where I can find a specification for "error tone" listed in
draft-boyle-megaco-alerting-03.txt?  I can't seem to find it.

Thanks.

RE: "Error tone" specification

Looking at the document, I would guess this would be defined by local
practice.  I'm not sure I've ever experienced a tone like this -- the only
data input situations I can think of involved announcements.  For something
where you wanted to abort a session, of course, you could use reorder tone.
I expect you'd want to make that signal type OO rather than brief.

Re: Mode in LocalControl ***

RE: Mode in LocalControl ***

I suppose one could rephrase 6.1.1 to say that MODE controls the flow of
media THROUGH an individual termination, while topology controls the flow of
media across the centre of the context.

Hi, 
A while ago there was a discussion about the use of mode in "internal"
terminations, eg a MUX termination. It was then said that mode can be used
even for such terminations, to describe the media flow.

However, chapter 6.1.1 very cleary says that MODE is used for the media flow
of the media at the ingress/egress of the media gateway, and that TOPOLOGY
is used for media between terminations within a context. By reading that
text one DOES get the understanding that mode is not needed for the mux
termination, so my question is if some clarifications are needed?

The default value for Mode is inactive.  That means you MUST set it on all
terminations through which you want media to flow.
