Abstract
A method for incorporating a non-redundant component in a redundant system in a communications network, the redundant system having first and second redundant components providing first and second data streams and activity signals, respectively, the activity signals indicating which of the first and second data streams is an active data stream, the first and second data streams being unsynchronized, the method comprising: determining whether an activity switch has occurred from the activity signals; responsive to the determining, selecting an input data stream from among the first and second data streams; filtering the selected input data stream to produce an output data stream by nullifying any incorrect control information inserted into a packet in the input data stream due to the selecting; and, providing the output data stream to the non-redundant component.
