Did you try lines 6 , 7 and 8?

Did you press the Amp cable in tight to the CICS?

Did you re-punch the cable pairs on the back if using BIX or inspect connections on those primitive 66 blocks?

Try another Amp cable?

Making a couple test AMP cables using a BIX36B (or equivalent) is very helpfully
Plug into KSU then try toner in each jack/port.
Test done under a minute.

Did you check Maintenance to see if port 205 is Idle?
Might tell if a software/hardware issue.
