[cssm] Use of SICF in service managemnt

[Martin.Unal at esa.int]

Hello

Recent  ESA missions use multiple instances per file, and individual files 
per functional group.
Individual instance covers for various combination of service 
(Timely/Complete) for each VC. Complemented by cltu and offline as needed.
The functional group is used to differentiate different band (e.g. X/KA) 
or mode (e.g. Safe vs nominal)
e.g. JUICE
FG1     13 SIs
FG2     6 Sis
FG3     12 Sis
FG4     6 Sis

This means 4 files for each SLE providers.
Just for ESTRACK, 3 stations with prime+backup = 24 files for a total of 
222 SIs.

CFDP makes the picture a bit more complex as we have CFDP provider at the 
station which also connect to the SLE providers with their own SIs.
We have no fsp usage so far. But on paper it allows more complex scenario.

However, the usage is quite simple in term of support request. (at least 
for ESTRACK)
Our tailoring defines a high level support type which refer to an agreed 
configuration.
Most mission have only one, the most complex has 5.
e.g.
TTC_1,          X/X
TTC_2           S/X (MEX)
DDOR_1  X
DDOR_2  Ka (Bepi)

SICF are loaded as required by the support type.
On top of the support type, some parameters can be used to specify TM/TC 
rate or the DDOR sequence. But this as no influence on the SICF usage.

In summary, internally to ESTRACK, the "service type" string is sufficient 
to refers to all SICF needed for the support.

Dear all, 
                  just working thro' what using the SICF means for the 
SMURF and SPDF, if my memory serves me correctly there should be one and 
only one SICF used during a pass. This being the case it would imply that 
per service package there would be at most one SICF referenced. Also I 
think that the SICF would be needed for Offline Services. 

Are these valid assumptions ? 

Cheers for now, 

Colin
