Call Collision

Call Collision is the contention that occurs when a terminal and data circuit-terminating equipment (DCE) specify the same channel at the same time to transfer a call request and handle an incoming call. When call collision occurs, the DCE proceeds with the call request and cancels the incoming call. Call collision also refers to the condition that occurs when a trunk or channel is seized at both ends simultaneously, thereby blocking a call.
