Abstract:
A control apparatus capable of being implemented within a switching card coupled to at least two signal transmission means, the control apparatus being input with an input line condition (ILC) with respect to one of the two signal transmission means and outputting a corresponding output line condition (OLC) with use of line condition control (LCC) logic operating within the control apparatus; andwherein the LCC logic is capable of activating a protection oscillation control (POC) mechanism for a hold time if the ILC is detected to be oscillating between a maximum failure priority condition and a non-maximum failure priority condition, setting the OLC equal to a first failure priority condition that is less than the maximum failure priority condition if the POC mechanism is activated, and setting the OLC equal to the corresponding ILC if the POC mechanism is not activated.
