CSTSWG colleagues,
Finalizing implementation of Monitored Data Service, I think we found an
error in the ASN1 : the TypeAndValue type is defined as follows :
TypeAndValue ::= CHOICE
{ integer [0] INTEGER
, intUnsigned [1] IntUnsigned
, duration [2] Duration
, characterString [3] VisibleString
, boolean [4] BOOLEAN
, octetString [5] OCTET STRING
, float [6] REAL
, time [7] IntUnsigned
, enumerated [8] IntUnsigned
, valueExtension [100] Extended
}
the "time" choice is currently defined as an "IntUnsigned". I think this
field should be defined as "Time" defined just above in the ASN.1 :
Time ::= CHOICE
{ ccsdsFormatMilliseconds [0] TimeCCSDSMilli
, ccsdsFormatPicoseconds [1] TimeCCSDSPico
}
TimeCCSDSMilli ::= OCTET STRING (SIZE(8))
TimeCCSDSPico ::= OCTET STRING (SIZE(10))
regards,
Cyril.
