A method and system of the present inventions reduces both near-end crosstalk and far-end crosstalk interferences due to handshake tones into upstream and downstream neighboring services, both at the customer premises equipment and at the central office, when handshake is experienced. Each pixel unit includes a pixel electrode, a common electrode, and a coupling member. A film cooperates with the support, to define a wicking channel. Then, at the character string extraction step, elements of the character string are designated that correspond to elements included in the range of the suffix array, and character string segments are extracted consisting of the same number of elements as the elements of the pattern and having the elements of the character string as their first characters. Alternatively, by modifying an upper end portion of the production platform using associated conversion apparatus, the same platform may be converted to a power vented water heater subassembly, a natural draft direct vent water heater subassembly, or a powered direct vent water heater subassembly to thereby lower the overall production costs for these different types of fuel-fired water heaters.
