Dear Mr. Harasaki,
Thanks for your confidence in me.
The followings are my comments regarding Section_8.3. If you think using Section_8.3 for both point-to-point and point-to-multipoint configurations is ok, I can modify this specific section to reflect your comments.
Since initial VC is used for a transport of H.245 messages, it must be >bi-directional point-to-point VC connection.
Yes, you are right.
Either MCU or aterminal can initiate the call.
In the root-initiated point-to-multipoint case, it's still MCU who should initiated the call since the addditional VC is setup by the calling party, the party who initiated the first VC (Do I understand H.310 procedure right?)
A point-to-multipoint VC connection can only be used in an additional >VC setup phase. The additional VC is used for AV communication.
You are right. I should only put change in the addtional VC setup.
We may need to put some guidelines for selecting point-to-point and >point-to-multipoint VC. In the case of one SOT and many ROTs case >shown in Figure 3 (b), MCU shall initiate point-to-multipoint VC >connection as an additional
I agree. But I don't want to make it mandatory.
I would like to add something like below in Section 7 or 8.
"MCU shall use point-to-multipoint VC connection for all receive only >terminals. ROT terminals are always receive only.
I understand that it's more efficent to use point-to-multipoint VC connection for ROTs but I am not so sure about making this mandatory. I do not want to exclude the case, where for some reason, MCU does not support Q.2971 but still want to support ROTs. Then in this case, MCU should be able to use point-to-point connection to support ROTS.
If I understand correctly, Information Elements that are used for point-to-multipoint VC setup is exactly same as a uni-directional point-to-point VC setup, except user plane configuration field of B-BC and Endpoint Reference IE.
I will cut from Table B.3/H.310, modify it and paste the revised table into Annex A.
This is good enough for me.
