which the FSH_SDU is to be transferred.
NOTE – The GVCID parameter is the SAP address of the VC_FSH Service.
126.96.36.199 FSH_SDU Loss Flag The FSH_SDU Loss Flag is an optional parameter that may be used to notify the user at the
receiving end of the VC_FSH Service that a sequence discontinuity has been detected and
that one or more FSH_SDUs may have been lost. If implemented, the flag shall be derived
by examining the Virtual Channel Frame Count in the Transfer Frames.

b) VC_FSH.indication. CCSDS 132.0-B-1 Page 3-10 September 2003 CCSDS RECOMMENDATION FOR TM SPACE DATA LINK PROTOCOL 184.108.40.206 VC_FSH.request 220.127.116.11.1 Function At the sending end, the VC_FSH Service user shall pass a VC_FSH.request primitive to the
service provider to request that an FSH_SDU be transferred to the user at the receiving end
through the specified Virtual Channel.
NOTE – The VC_FSH.request primitive shall be the service request primitive for the
18.104.22.168.2 Semantics The VC_FSH.request primitive shall provide parameters as follows:
VC_FSH.request 22.214.171.124.3 (FSH_SDU,
GVCID) When Generated The VC_FSH.request primitive shall be passed to the service provider to request it to send

188.8.131.52.5 Additional Comments
The VC_FSH.request primitive shall be used to transfer FSH_SDUs across the space link on
the specified Virtual Channel.
Function At the sending end, the service provider shall pass a VC_FSH.indication to the VC_FSH
Service user at the receiving end to deliver an FSH_SDU.
NOTE – The VC_FSH.indication primitive shall be the service indication primitive for the
VC_FSH Service. CCSDS 132.0-B-1 Page 3-11 September...
