A communications network test system facilitates autonomous or attendant-free interaction between the administrative interfaces of multiple network devices under test. The traffic information can include movement information including detected stops and durations of detected stops. For example, the IC has a single parallel interface, which is used as a parallel input in the first mode, and as a parallel output in the second mode. A generation program selects from the database the elements that can make a contribution to the conversion of the new route allocation, and automatically parameterizes these elements using the adoptable switching states and their effect. Longitudinal translation structure provides for compensation in the length of the structure when the supports are angled upwardly or downwardly. By including a scope restriction in the search query, the search results identified from the content index are limited to results that match the scope restriction.
