BSO CAD and Radio Troubles

Late Saturday morning Broward Sheriff's Office consoles and/or computer-aided dispatch (or both) failed. As of 12:50 there was a county-wide announcement that 8TAC91 (851.5125MHz) would be reserved for emergency traffic only in case the radio system failed again.

Apparently as the technicians are working on the radio system they are dispatching for a 20 minute window via hotline telephone and reserving that conventional frequency above for emergencies only.
