Narrative:

First officer (PF) descending to 12000 ft MSL. Captain and first officer both called passing 13000 ft for 12000 ft. ATC gave turn (vector) and runway for landing. First officer commenced turn and began briefing approach. Aircraft was high and close entering downwind. During brief, first officer noticed aircraft nearing 11300 ft MSL and began immediate climb to 12000 ft MSL. Very soon after reaching 12000 ft, ATC gave descent clearance. There was no conflict with any other aircraft from ATC or on TCASII. Conclusions: 1) PF should brief during low workload times and give aircraft to PNF while briefing, 2) ATC should plan for arriving aircraft better and give aircrews more time to plan and set-up for the approach by giving expected runway to aircrews as far from airfield as possible.
