Abstract
An add-on system as disclosed for use with an existing multilevel antennae switching matrix of the type having a plurality of input ports, each supplied by a respective input signal source with at least one unused input port being available and a plurality of output ports are connected to receivers. The add-on system uses a plurality of switching devices which are each selectively operable to couple each of the input signal sources to a different one of the unused input ports. This provides that when an attempt to effect an interconnection between a desired one of the input ports and a desired output port is blocked then the input signal source which supplies the desired input port associated with an attempt connection is coupled to any one of the unused input ports for facilitating the connection at that port to the desired output port.
