When a subscriber is on a non-emergency traffic channel, it will receive an Error-481 if an Emergency Dispatch Call contends for and is assigned to that same traffic channel resource. For the non-emergency user, there are no details at the subscriber level to indicate what has actually happened. As designed, the channel is ruthlessly preempted from the non-emergency user and given to the emergency requestor by the Access Controller Gateway (ACG).
