Note

Status Codes are returned in DIMSE response messages (see PS3.7). The code values stated in column "Status Codes" are returned in Status Command Element (0000,0900).

Some Failure Status Codes are implementation specific.

An SCP implementation shall assign specific Failure Status Codes by replacing each 'x' symbol with a hexadecimal digit in the range from 0 to F. An SCP implementation wishing to differentiate between causes of “Failed: Unable to process” Failure Meaning shall assign those causes specific Status Code Values within valid range specified in Table CC.2.8-2.

An SCU implementation shall recognize any Failure Status Code within the value range specified in Table CC.2.8-2 as an indicator of the Failure Meaning stated in the table. There is no requirement for an SCU implementation to differentiate between specific Status Codes within the valid range.
