The invention relates to a transparent balustrade of an escalator or of a moving walk, comprising a balustrade skirt, at least one glass panel, and a handrail guide with a handrail. The cross-car bow is movable laterally within the cross-car rail bracket to allow for a single cross-car bow in a variety of locations within the tonneau cover frame. A display unit receives the rf transmissions from the traps and identifies and displays the then current state of each trap. Hence, a root node of an aggregation group can filter group-specific routing information from packets destined toward a network clusterhead, resulting in a scalable routing protocol that is not adversely affected by added nodes.
