CALL COLLISION

1. 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. Note: When call collision occurs, the DCE proceeds with the call request and cancels the incoming call. 2. The condition that occurs when a trunk or channel is seized at both ends simultaneously, thereby blocking a call. ( 188 ) Deprecated synonym glare.
