A brief update:<br>
<br>
OID - the action on NASA/GSFC is closed. V. Sank confirmed the feasibility
and the agreement (making the random pattern OID mandatory) is confirmed<br>
<br>
USLP - the second action refers specifically to the concerns raised by
Wolfgang Hell about "systematic retransmission" in section 4.2.10.8
of USLP with respect to 231.0<br>
I'm sorry that my formulation in yesterday's notes was not clear.<br>

<br>
Dear all,<br>
<br>
a very brief summary of our discussion:<br>
<br>
- OID<br>
Most of the participants agreed to make the proposal (OID random pattern)
mandatory.<br>
Participants from NASA/GSFC asked for more time to confirm (or not) the
decision<br>
The proposal, once agreed, will be anyway subject to Agency Review<br>
AI (V. Sank): report NASA/GSFC position by end of December 12<br>
<br>
- TERMINOLOGY<br>
G. Kazz/NASA presented a proposal to align the terminology (regarding re-transmission)
of the protocol books (232.1-B-2 and 232.0-B-3) to that used in the coding<br>
book (231.0-B)<br>
G. P. Calzolari/AD stated that the change of terminology was not actually
required, and proper referencing inside the protocol books would achieve
the target.<br>
This will translate in actions internal to the SLP WG and the issue, from
the joint C&S/SLP point of view, is closed<br>
<br>
- USLP<br>
G. Kazz/NASA presented the (limited) changes required in 231.0-B (TC coding
book) in order to reference 732.1 (USLP), stating how USLP already foresees
this service<br>
It was agreed background underlying the actual need for this change (possibly
linked to Lunar missions) will be provide.<br>
Besides, it was agreed to provide material (presentation/paper...) to show
how the use of USLP would not be detrimental<br>
to the TC service<br>
AI (G. Kazz): provide rationale for the change<br>
AI (G. Kazz): provide material about use of USLP with TC, showing compatibility<br>

Dear all,<br>
<br>
based on the results of the poll, we are going to have a first joint C&S/SLP
discussion on the following topics on Thursday 5 December, starting at
4pm (CET).<br>
<br>
- introduction of OID random pattern<br>
- possible alignment of terminology in the TC books regarding retransmission<br>
- additionally, SLP would like to discuss adding USLP to the TC coding
book and assessing its impact (other books are mentioned in the presentation,
but agreement on these ones has already been reached)<br>
