A distributed control exchange according to the present invention is provided with a plurality of sections for executing, in the form of a distributed process, a call process for a call occurred at an individual line. The approach includes a step of detecting whether a computer system is coupled to a packet switched network via the first communications line and if the computer system is coupled to the packet switched network, a step of concurrently enabling voice communications over the first communications line using a first voice telephony device coupled to the computer system. It also includes a first PDU configured to supply electrical power to the plurality of electronic components. at a pressure ranging from about vacuum conditions to about 20,700 kPa for a time sufficient to crack the biomass oil. Information related to the identified communication chains can be presented to a user via an interactive network graph that supports iterative analysis of the communication-chain data. The resulting probabilities are coded in a pseudocolor scale and they are superimposed on a Anatomical Atlas for their interactive three-dimensional visualization.
