The invention provides a process for the preparation of hydrogen peroxide by hydrogenating 3-2–2-quinoxalinone in the presence of a palladium catalyst and contacting the 3-2–1,2,3,4-tetrahydro-2-quinoxalinone with oxidant molecular oxygen or air in ethylacetate-water or chloroform-water biphasic system. A mounting plate has the second end of the base assembly rotatably connected thereto such that the base assembly is movable between first and second positions. When it is determined that quality of service for voice conversations for one or more contact centers is at risk due to a health status parameter of a network segment reaching a threshold, an appropriate system reaction is triggered.
