NET-09More than 2 concurrent associations

What this test proves

A server must accept more than two modalities at once (Pro).

How it is tested

  1. Start a DicomServer with AE title DICOMKIT_SCP on 127.0.0.1 (free port)
  2. Open three a DicomClient with AE title DICOMKIT_SCU associations and keep them open
  3. If the third is rejected with A-ASSOCIATE-RJ (local limit exceeded), report refused
  4. Otherwise pass if C-ECHO returns 0x0000 on all three

Expected result for each license type

  • No key: Asks for key: stops and asks for a license key
  • Developer: Works
  • Pro: Works
  • Enterprise: Works
  • Expired: Refused: refused, naming the required tier (basics keep working)
  • Revoked: Refused: refused, naming the required tier (basics keep working)
