No. I never did get to talk to you in Oslo. Sorry about that, but maybe we can get together in Redbank.

This document mentions H.248 MG requirements for the MIB. Is anywork being started on the MIB? Irina.

The text below lists additions and clarifications made to <draft-ietf-megaco-reqs-05.txt>, and now found in <draft-ietf-megaco-reqs-06.txt>.
Until it is available in the IETF I-D directory, you can get a copy of
it
at: ftp://standards.nortelnetworks.com/megaco/docs/latest
It includes clarifications asked for by ITU-T SG16 at their Berlin meeting.
If there are no more comments on this requirements draft, then I would ask Tom Taylor to send it for WG last call.
Note that there are references to fill in, and a few editor's notes to remove. I will do this in a few days if there are no other comments.

5.4. Signal/Event Processing and Scripting
l. Provide an extension mechanism for implementation defined events and signals with, for example, IANA registration procedures. [ADD FOLLOWING SENTENCE:]It may be useful to have an Organizational Identifier (i.e.
ITU,
ETSI, ANSI. . .) as part of the registration mechanism.
5.6. Test Support
b. Specifically support [DELETE103, 105, and 108 ] test line operation [ADD] (e.g. 103, 105, 108).
5.8. Signalling Control
Establishment and provisioning of signalling backhaul channels (via SIGTRAN for example is out of scope. [QUESTION: WHY was this marked as
out
of scope?] Answer: it has been decided that this capability is not fundamental to the protocol, so can be kept out of scope, and handled some other
way.
6.1. Resource Status Management
c. Provide a method for the MGC to request that the MG release all resources [ADD THE FOLLOWING] under the control of a particular MGC [END OF ADD] currently in use, or reserved, for any or all connections.
6.2. Resource Assignment
c. Allow the use of DNS names and IP addresses to identify MGs and MGCs. [ADD FOLLOWING SENTENCE] This shall not preclude using other identifiers for MGs or MGCs when other non IP transport technologies for the
protocol
are used.
8.1 MG-MGC Association Requirements
b. Allow multiple MGCs to send control messages to an MG. Thus, the protocol must allow control messages from multiple [DELETE] IP [ADD]signalling addresses to a single MG.
7.3 MIB Requirements
[ADD c.] c. H.248 MG MIB must support spirit of H.341 by either the MG, MGC, or both acting together.
8.2. Performance Requirements
d. Support peak calling rates (e.g. in the order of 140 calls/second)
at
the MGC on a moderately loaded [DELETE IP] IP network.

11.1.1. Requirements for TDM PSTN (Circuit)
b. Missing - inconsistent numbering - renumber section
11.1.3.3. Media adaptation
b. Allow [ADD AAL1] AAL1/AAL2 multiple narrow-band calls to be mapped
to
a single VCC. [ADD For AAL2] For AAL2, these calls are differentiated within each VCC by a AAL2 channel identifier. An AAL2 connection may span more than 1 VCC and transit AAL2 switching devices. ATMF standards are working on an end-to-end AAL2 connection identifier as part of the AAL2 signalling set.[REPLACE LAST SENTENCE WITH:] ITU Q.2630.1 defines an end-to-end identifier the Served User Generated Reference (SUGR). It carries information from the originating user of the AAL2 signalling protocol to the terminating user transparently and unmodified.
11.2.10. Multipoint Control Units
[ADD g.] g. The ability for the MG to function as an H.323 MP, and for the MGC to function as an H.323 MC, connected by this protocol (MEGACOP/H.248). It should
be
possible for audio, data, and video MG/MPs to be physically separate while being under the control of a single MGC/H.323 MC.
