Are you refering to what we call the circuit in the UK?
If I understand you correctly you are asking about the differences between a visual circuit and a circling manouver in a jet.
A visual circuit is an entirely visual exercise usually flown for take-off and landing practice where as circling is a manouver flown from an IFR approach where it is not possible to land directly after becoming visual (i.e. tailwind). Most circling manouvers are usually flown fully configured for landing at a lower speed (to keep turn radius down and airfield in sight)and at lower height than a circuit (normal pattern).
Hope this helps. It is the same for jet and non-jet aircraft btw.
