directive. As I noted during last week’s brief discussion, the procedures that comprise the MD service (Association Control, On-Change-Option-Cyclic Report (derived from Cyclic Report), Information Query, and Notification) all have configuration parameters
that are static (not dynamically reconfigurable). The configurable parameters of the MdCstsProvider FR consist of these static configuration parameters PLUS one other configurable parameter –

parameter, SFW B-2, is mute on the point of whether or not the parameter is dynamically reconfigurable. Because this parameter represents a mutually-agreed value between service user and service provider about when an abort situation exists, my belief is that
this should be a static configuration parameter. If that is the consensus of the WG, then there would be no dynamically-configurable parameters of the MD service and thus no need for the

event. Originally, (and this is the way it is written in the B-1 version of the MD-CSTS book), I had envisioned a Monitored Data Collection FR to represent the functionality of making the parameter values and events of all FR instances of a Service Package
available to the MD service instance. As part of this approach, the production status of the MD service was defined to be strictly and solely the resource status of the MD Collection FR. The motivation for this definition was, frankly, to avoid having to define
what an operational production status would be for the MD service when in a sense the true production comprised all of the FRs in the Service Package. The MD Collection FR would have no configuration parameters (hence, no need for an

<p class="MsoNormal"><span style="color:#1F4E79;mso-style-textfill-fill-color:#1F4E79;mso-style-textfill-fill-alpha:100.0%">Subsequently, I had difficulty justifying the existence of the MD Collection FR, in particular as something that an ESLT would have to
“implement” – there was nothing to configure, and its resource status (its only reportable parameter) was itself vaguely and circularly defined. So I deleted the MD Collection FR.

<p class="MsoNormal"><span style="color:#1F4E79;mso-style-textfill-fill-color:#1F4E79;mso-style-textfill-fill-alpha:100.0%">But that deletion re-raises the question that I had tried to abstract away with the MD Collection FR, namely, what is the production
status of the MdCstsProvider FR? We not only have address this for the FR definition in the Tier-1 FR SANA registry but also in the upcoming revision of the MD book itself.

<p class="MsoNormal"><span style="color:#1F4E79;mso-style-textfill-fill-color:#1F4E79;mso-style-textfill-fill-alpha:100.0%">My current thinking is to treat the production status of the MD service instance as essentially the status of the Service Package as

is able to report something for every FR in the Service Package, even if that something is ‘unavailable’, then the Service Package – and therefore

<span style="color:red">WH: Because of the CHOICE, in case of never, no engineering unit applies, while in case of timeLimited the engineering unit is hour. In such case I filled in the Engineering Unit field with "N/A / hour". I'm not sating that one has to
do it that way - I can also live with leaving the Engineering Unit field blank. But a uniform approach would be nice. Also, to make the ASN.1 as informative as possible, I suggest to add a comment to the timeLimited element specifying the applicable engineering
unit. Perhaps I'm overly ambitious by always trying to specify a value range constraint that looks realistic for the specific parameter. LongIntPos is certainly more than ever needed.

Subject: Tier 1 frm file updated as per our "Three-way" discussion<o:p></o:p></p>
<p class="MsoPlainText"> <o:p></o:p></p>
<p class="MsoPlainText">Dear Holger and John,<o:p></o:p></p>
<p class="MsoPlainText"> <o:p></o:p></p>
<p class="MsoPlainText">As agreed in yesterday's telecon I have updated the Tier 1 frm file in accordance with the outcome of our discussion. We concluded that in the context of CCSDS 401 there is no need to explicitly reference the FR instance generating the
forward carrier. However, given that spacecraft may have more than one forward link typically each of them operating in a different frequency band, one should know to which of the forward links the return signal is coherent. This could be indicated by simply
stating the frequency band of the "coherency" forward link. <o:p></o:p></p>
<p class="MsoPlainText">Alternatively one can express this by means of the transponder ratio.
<o:p></o:p></p>
<p class="MsoPlainText">This option has the advantage that this covers also multi-spacecraft arrangements where those spacecraft share the same forward physical channel, but use different SCIDS or VCID sets or APID sets. In order to get separate return physical
channels in the same frequency band, one can use non-standard transponder ratios. Therefore the transponder ratio parameter shall permit the specification of non-CCSDS transponder ratios. At this point we cannot exclude that in the context of CCSDS 415 a different
mechanism will be necessary for identifying the forward link to which the given return link is coherent. We agreed that we will work that out when the CCSDS 415 related FR types will be specified, but we will not worry about it in the context of the Tier 1
and Tier 2 FRM delivery.<o:p></o:p></p>
<p class="MsoPlainText"> <o:p></o:p></p>
<p class="MsoPlainText">Please find attached the Tier 1 frm file modified as outlined above.<o:p></o:p></p>
<p class="MsoPlainText"> <o:p></o:p></p>
<p class="MsoPlainText">Best regards,<o:p></o:p></p>
