which the OCF_SDU is to be transferred.
NOTE – The GVCID parameter is the SAP address of the VC_OCF Service.
126.96.36.199 OCF_SDU Loss Flag The OCF_SDU Loss Flag is an optional parameter that may be used to notify the user at the
receiving end of the VC_OCF Service that a sequence discontinuity has been detected and
that one or more OCF_SDUs may have been lost. If implemented, the flag shall be derived
by examining the Virtual Channel Frame Count in the Transfer Frames.
3.6.3 VC_OCF SERVICE PRIMITIVES
188.8.131.52 General The service primitives associated with the VC_OCF Service are:
Function At the sending end, the VC_OCF Service user shall pass a VC_OCF.request primitive to the
service provider to request that an OCF_SDU be transferred to the user at the receiving end
through the specified Virtual Channel. CCSDS 132.0-B-1 Page 3-13 September 2003 CCSDS RECOMMENDATION FOR TM SPACE DATA LINK PROTOCOL NOTE – The VC_OCF.request primitive is the service request primitive for the VC_OCF

The VC_OCF.request primitive shall be used to transfer OCF_SDUs across the space link on
the specified Virtual Channel.
126.96.36.199 VC_OCF.indication 188.8.131.52.1 Function At the sending end, the service provider shall pass a VC_OCF.indication to the VC_OCF
Service user at the receiving end to deliver an OCF_SDU.
