Pictured is the Communications room in the RAC building, Research Analysis Center. This is the hub for the CATV and Lynk system and also the telephone system as seen from the twisted pair wires. The test gear LAN 450 is on the floor and is a spectrum analyzer made specifically for CATV. The Large boxes on the wall are Trunk amps and the smaller boxes are Splitters or combiners.
