Abstract: A rotatable cooling module includes a cooling coil. An input line is coupled to the cooling coil via a coupler that allows the cooling coil to rotate independent of the input line. An output line is coupled to the cooling coil via a second coupler that allows the cooling coil to rotate independent of the output line. A coolant flows through the input line and the first coupler and passes through the cooling coil, which removes heat from an electronic assembly to which the cooling unit is attached. The coolant then flows through the second coupler and through the output line and returns to a heat exchanger, which cools the liquid before recirculating through the cooling unit. The couplers are disposed about a single axis which allows the cooling module to be rotated, and the couplers prevent damage from occurring to any of the elements of the cooling module.

Abstract: A method of monitoring DS-0 alarm signals generated by telecommunication network elements, where the network elements include multiple network processing circuits connected to DS-1 facilities. The method comprises the steps of collecting the DS-0 alarm signals; cross-referencing the network elements and the network processing circuits to the DS-1 facilities; correlating the DS-1 facilities to customer circuit identification information; and routing the DS-0 alarm signals to a user location. The method allows a user to view customer outages in real time and also permits proactive observation and analysis of developing problems.
