The command tools>perform>aps>force>working forces an activity switch away from the working line to the protection line unless a request of equal or higher priority is already in effect. When the forced switch of working to protection command is in effect, it may be overridden either by a lockout command or by a signal fault on the protection line. If the active line is already on the protection line, no action takes place. Refer to the 7705 SAR OAM and Diagnostics Guide, ‟Tools”, for information on the APS force command.
