7. PROTECTION SWITCH In-Band Slot Enable/Disable Protocol See Table 4 for in-band slot enable/disable protocol. Remote provisioning for a protection switch can be accomplished by sending a specific sequence of in-band or out-of-band messages. These remote provisioning commands are transmitted to the controller card from a remote test facility or a T1 test set at a DSX panel. Arming Arming the controller card prevents an inadvertent protection switch operation. The controller card can be armed
