Essentially, a switching sheet is created and implemented simultaneously. Steps are recorded on the Steps tab as the Control Tool actions are being performed, and each step is considered complete as it is being recorded.

Emergency switching operates just like planned switching, except that the Web Switching Management window and Viewer must both be in real-time mode. Whenever switching steps are recorded in a switching sheet using the real-time Control Tool, the operation is considered emergency switching.
