An address generator holds a cell list of cell data of a central cell containing a central particle and a predetermined number of surrounding cells located around the central cell in a system. The method on the system performs the following: downloading from the telephone network service those telephone identifiers eligible to communicate with said network node, and downloading indications of allowable services associated with each telephone identifier. In preferred devices, the first and second metal microtips and metal oxide comprise a monolithic, unitary structure. In order to enable the surge arrester mounting unit also to be used for terminal blocks with high transmission rates, the invention provides for the contact blades for separating contact fingers ), from insulation piercing contact elements to be made approximately twice as long as the spring arms and to be given more than double the material thickness at the free end by bending over. An anisotropic conductor is disposed between the wafer and the translator plate. Excess thermoplastic material is trimmed off after the thermoforming process to produce a thermoformed piece.
